Project power and control planning
Motorized Blinds Voltage & Power Guide
Confirm destination power, the selected shading system and the required control path before a motor is quoted. This procurement guide helps dealers, contractors, electricians and integrators prepare a reviewable brief for 24V DC, 110/120V and 220/230V projects.
- Country power and frequency
- Wired, rechargeable or low-voltage direction
- Control and responsibility handoff
Why this comes first
Power and Control Affect the Product Configuration
A voltage label alone does not select a motor. Shade or track type, size and load, motor model, available power, cable route, controller and project platform must be reviewed together. The final quotation should identify the selected path rather than assume that one motor works with every market or control system.
- Destination
- Country, available supply and 50Hz or 60Hz project condition.
- System
- Blind, shade or curtain-track type, dimensions, fabric and operating load.
- Control
- Local control, dry contact, RS485, app/gateway or project-specific integration.
- Responsibility
- Power, wiring, interface, installation, programming, testing and commissioning owners.
Power architecture
Separate 24V DC and Mains-Powered Concepts
These are planning categories, not universal compatibility statements. Exact motor and power-supply selection remains product- and project-specific.
24V DC direction
Record the proposed power-supply location, cable route, voltage-drop considerations, access and the equipment that converts local mains power where required.
110/120V projects
Confirm the selected motor model, frequency, local electrical provisions and control interface. Do not substitute a market voltage assumption for the model documentation.
220/230V projects
Confirm the same model-level information, including frequency, wiring, local isolation and access. A motor offered for one mains condition is not automatically approved for another.
Model-level confirmation
What 50Hz and 60Hz Mean for Procurement
The project team should provide the destination supply and frequency before the motor is frozen. Saiwenna then maps that information to the documented selected motor, controller and power-supply path. No catalog-wide frequency compatibility is implied.
| Input | Why it matters | Required confirmation |
|---|---|---|
| Country and site supply | Defines the project electrical context | Voltage, frequency and responsible electrical discipline |
| Selected shading system | Load and operating method affect motor selection | System type, opening dimensions, fabric and quantity |
| Power location | Affects cable route, enclosure and service access | Point location, access and installation responsibility |
| Control platform | Determines whether an interface, gateway or controller is needed | Exact platform, commands, feedback and commissioning owner |
Project type
Wired, Rechargeable and Retrofit Planning
New construction
Coordinate recesses, pockets, drive side, cable routes, power points and access before finishes close. Keep the shading, electrical and control drawings aligned.
Retrofit
Record the existing opening, accessible power, finished surfaces, routing limits and acceptable visible components before choosing a direction.
Rechargeable or battery direction
Confirm that the selected product and motor support the proposed option, then review charging access, user expectations and service responsibility.
Control boundaries
Name the Exact Command Path
A control request must identify how the command reaches the selected motor and who owns the interface. Terms such as smart home, KNX, BMS or Lutron do not prove compatibility by themselves.
Remote or wall control
Confirm the exact selected receiver/controller, grouping needs and local operating method.
Dry contact
Confirm the selected model, electrical input and available commands. Dry contact does not imply position feedback.
RS485
Provide protocol, addressing, topology, commands and feedback requirements for the exact device path.
Wi-Fi or app
Confirm the selected motor/controller or gateway, account, region, network and supported functions.
Lutron projects
Identify the project system, selected shading path, interface, bill of materials and integrator responsibility. No partnership or universal compatibility is implied.
KNX or BMS
Provide the project platform and a documented actuator, gateway or controller path. Final mapping is project-specific.
Quotation input
What Your Electrician or Integrator Should Confirm
- Local supply voltage and frequency
- Proposed power point or low-voltage supply location
- Cable route, conductor responsibility and site isolation
- Drive side and service-access requirement
- Local and central command requirements
- Exact platform, controller, gateway or actuator if selected
- Open, close, stop, group, preset and feedback needs
- Wiring, programming, testing and commissioning responsibilities
- Drawing revision used for coordination
- Applicable local electrical review and approval
Buyer handoff
What to Send Saiwenna Before Quotation
- 1. Opening schedule
System type, IDs, dimensions, quantity and mounting condition. - 2. Power information
Country, voltage, frequency, power-point plan and new-build or retrofit status. - 3. Control brief
Required operation, platform, interface, commands, feedback and responsible parties.
Local Mains Input Is Not the Motor-Side Output
In a low-voltage arrangement, the power supply accepts a documented mains input and delivers the output specified for the motor. Those are separate ratings. A mains-powered motor follows a different connection path. The controller may be built in or separate; command wiring is not interchangeable with motor power wiring.
- Site mains input
Record voltage and frequency at the installation.
- Selected power supply, where required
Check its input rating, output rating and accessible location.
- Documented motor-side supply
Match the motor rating and approved connection instructions.
Central Panel or Individual Local Power Supply?
| Planning factor | Central low-voltage panel | Individual/local supply |
|---|---|---|
| Selected motor and load | Document allocation and output limits for each motor group | Document a suitable supply for each assigned motor or group |
| Cable distance | Review each remote route and voltage drop against equipment documentation | Review both local mains access and motor-side cable route |
| Shade count and grouping | Keep output/channel IDs traceable to openings; do not equate control groups with power capacity | Keep supply identity and service location traceable at each opening |
| Service and panel space | Provide accessible panel position, labels and agreed maintenance responsibility | Provide accessible local supplies; do not conceal them behind permanent finishes |
| Electrical responsibility | Appointed electrical designer/installer checks protection, cable selection and local requirements | The same responsibility applies even when the layout uses fewer centralized components |
Neither arrangement is a default winner. Record the proposal in the Selected-System Power Output Allocation Schedule before accepting the route. No cable sizing or panel capacity is calculated here.
Documented Model Examples
These are documented examples, not universal recommendations or catalog-wide compatibility claims. Each row identifies the motor and its named system; actual selection still depends on the system load and equipment instructions.
| System / motor | Documented supply | Power / current | Torque | Documented speed |
|---|---|---|---|---|
| RC-MB10 / CM-50-E-R | 24 V DC | 38 W / 1.6 A | Maximum 6 Nm | 16 / 20 / 24 rpm; 20 rpm factory default |
| RC-MB10 / CM-10-QC | 230 V AC, 50 Hz | 133 W / 0.57 A | 8 Nm | 15 rpm |
| CC-B112 / CM-51-E | 24 V DC | 22 W / 0.9 A | 1.2 Nm | 13 cm/s curtain travel; 100 rpm shaft speed |
RC-MB10 technical sheet v1.0, page 2 (PDF); CC-B112 technical sheet v1.0, page 2 (PDF). Frequency is not assigned to the DC motor supply rows. The AC example documents 50 Hz only; it is not evidence of 60 Hz suitability. Curtain travel speed and shaft rotational speed are different quantities.
What You Receive From a Power & Control Review
| Buyer provides | Saiwenna reviews | Review output |
|---|---|---|
| Country, site voltage and frequency | Documented motor and power-supply paths | Suitable selection direction and unresolved ratings |
| Opening schedule, system and load inputs | System/motor requirements and available evidence | Shortlist direction or the missing engineering evidence |
| Existing wiring and service access | Mains, low-voltage or rechargeable planning constraints | Route for further electrical review and access questions |
| Control platform and responsible integrator | Native, interface or gateway path | Required interface evidence and responsibility boundary |
| Required functions and feedback | Controller capability and acceptance needs | Functions supported by the evidence plus a list of open test items |
This is a review output, not final engineering approval. The appointed electrical professional and integrator remain responsible for their approved installation and commissioning scope.
Power Questions Buyers Often Need to Resolve
Can one project contain different voltage groups?
Yes, as separately selected and labeled configurations. Keep each motor, supply and opening group identifiable; never treat a mixed schedule as permission to interchange equipment.
Does 50 Hz versus 60 Hz affect selection?
It is part of a mains-input rating check. Match the selected motor or power supply to its documentation. The 230 V AC example above states 50 Hz and must not be assumed suitable for 60 Hz.
Where should a low-voltage power supply be located?
Where the selected equipment can be installed, connected and serviced within its documented limits. Compare panel space, accessible local space and actual cable routes before fixing a position.
What should the electrician prepare before quotation?
Site voltage/frequency, power-point locations, cable routes, isolation/access proposals and the drawing revision. Record which selections remain open rather than installing from a generic diagram.
When should wired versus rechargeable shading be reviewed?
Before finishes or electrical provisions are committed. For retrofit, include routing limitations and charging access; a rechargeable option still needs a supported motor/product configuration.
Can wall control and central automation coexist?
Only when the selected control path documents the required inputs and behavior. Record command priority, feedback and fallback needs, then use the bench-test acceptance record to check the agreed functions.
Ready to Confirm the Power and Control Direction?
Send the opening schedule, destination, available power, preferred control outcome and project responsibilities. Final equipment follows the documented selected configuration.
