Alpha WSER50 10/27 Universal 240V Radio Motor

The Alpha WSER50 10/27 Universal is a powerful 240V wired radio motor designed particularly for external straight-drop awning systems, as well as compatible roller blinds and roller shutters.

Alpha describes its WSER50 Universal range as its most popular external straight-drop motor series in Australia.

The WSER50 10/27 combines 10Nm of rated torque with a fast 27 rpm output speed, making it particularly useful for applications where responsive operation is desirable.

Unlike a basic mechanical-limit motor, the Alpha WSER50 incorporates an electronic limit switch, built-in radio receiver, wireless limit setting and torque-stop functionality.

Torque-Stop Function

One of the most important features of the Alpha WSER50 10/27 is its torque-stop functionality.

For compatible external straight-drop systems, the motor can detect increased resistance and stop based on torque rather than relying exclusively on a programmed electronic stopping position.

This provides several useful installation possibilities.

In compatible side-channel systems, torque stop can be used to stop the awning against physical stoppers at the upper position.

At the lower position, the same functionality can be used to tension the awning fabric.

Importantly, the torque-stop function can work alongside a conventionally programmed top limit. The electronic limit can therefore be established normally while torque stop provides additional functionality where required by the awning system.

Designed for External Straight-Drop Awnings

The WSER50 series has been developed with external straight-drop applications firmly in mind.

Its combination of electronic limits, torque detection, radio control and weather-sensor compatibility makes it particularly well suited to compatible external awning systems.

Alpha also lists roller blinds and roller shutters among the key applications for this motor.

Built-In Radio Receiver

The Alpha WSER50 10/27 has its radio receiver built directly into the motor.

This allows the motor to communicate with compatible Alpha radio controls without requiring a separate external radio receiver.

An external antenna supports the motor’s radio-control system.

This gives the WSER50 the convenience of wireless user control while the motor itself remains permanently powered from a 240V electrical supply.

Electronic Limits and Wireless Limit Setting

The Alpha WSER50 10/27 uses an electronic limit switch rather than conventional mechanical limit adjustment.

Upper and lower stopping positions can therefore be electronically programmed into the motor.

Alpha also specifies wireless limit setting, allowing compatible Alpha controls to be used during programming and adjustment.

Combined with the torque-stop functionality, this gives installers considerable flexibility when configuring compatible external awning systems.

Alpha Sun/Wind Sensor Compatibility

The WSER50 10/27 is suitable for use with the Alpha RS001 Sun/Wind Sensor and Alpha RS002 Sun/Wind Sensor.

These sensors can provide automatic protective operation based on environmental conditions.

This is particularly valuable for external awnings, where changing wind conditions can potentially place significant loads on an extended awning.

Sensor Failure Protection

The WSER50 has an additional protective feature when operating with compatible Alpha Sun/Wind Sensors.

Alpha specifies that the motor detects a pulse transmitted by the sensor approximately every 20 minutes.

If the awning is down and the motor does not receive the expected sensor signal for approximately 30 minutes, the awning will automatically rise.

The system effectively assumes that the sensor has failed or communication has been lost and retracts the awning as a protective measure.

This provides another layer of protection beyond normal wind-triggered operation.

Fast 27 RPM Operation

The Alpha WSER50 10/27 combines 10Nm of rated torque with an output speed of 27 rpm.

This relatively high operating speed allows compatible awnings, blinds and shutters to move efficiently between their programmed positions.

The motor uses a larger 45mm diameter motor body compared with the 35mm WSER40.

240V Wired Operation

The WSER50 10/27 is a 240V wired motor.

It should not be confused with Alpha’s WSERD rechargeable battery motors.

The WSER50 receives permanent mains power while incorporating its own radio receiver for wireless operation.

This combination makes it suitable for permanent motorised installations where wired power and remote control are required.

Compatible Accessories

These are worth making internal links on Frontline:

Alpha RS001 Sun/Wind Sensor

Alpha RS002 Sun/Wind Sensor

Alpha specifically identifies both sensors as suitable for the WSER50 Universal motor range, so these are strong legitimate internal links rather than inferred compatibility.

Electrical Installation

The Alpha WSER50 10/27 operates at 240V mains voltage.

Electrical installation must comply with applicable Australian electrical requirements and be completed by appropriately licensed personnel where required.

FAQs

What is the Alpha WSER50 10/27 designed for?

It is particularly suited to external straight-drop awning systems. Alpha also lists roller blinds and roller shutters as key applications.

What is the torque rating of the Alpha WSER50 10/27?

It provides 10Nm of rated torque with a relatively fast output speed of 27 rpm.

What does the torque-stop function do?

Torque stop allows the motor to stop when it detects the required resistance. In compatible straight-drop systems this can be used against upper stoppers and can also assist with tensioning the fabric when the awning is down.

Does the Alpha WSER50 have a built-in receiver?

Yes. The radio receiver is incorporated into the motor, along with an external antenna.

Does it have electronic limits?

Yes. The WSER50 10/27 uses an electronic limit switch and supports wireless limit setting.

Which Sun/Wind Sensors are compatible?

Alpha specifically states that the WSER50 Universal range is suitable for use with the Alpha RS001 and RS002 Sun/Wind Sensors.

What happens if the Sun/Wind Sensor stops communicating?

Alpha states that the motor expects a sensor pulse approximately every 20 minutes. If the awning is down and no signal is received for around 30 minutes, the motor automatically raises the awning as a protective measure.
