Alpha WSER50 30/17 No Molex

The Alpha WSER50 30/17 No Molex is a powerful 240V wired radio motor designed particularly for external straight-drop awning systems, as well as compatible roller blinds and roller shutters.

This specific No Molex version carries Alpha product code WSER50NM 30/17 and provides 30Nm of rated torque at 17 rpm.

It combines an electronic limit switch, built-in radio receiver, wireless limit setting, external antenna and Alpha’s torque-stop functionality within a 45mm diameter tubular motor.

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

Designed for External Straight-Drop Systems

The Alpha WSER50 30/17 No Molex is particularly suited to compatible external straight-drop awning systems.

External straight-drop systems can require more than simply establishing fixed upper and lower stopping positions. Side-channel systems may incorporate physical upper stoppers, while the fabric may require tension at the bottom of its travel.

Alpha’s torque-stop functionality allows the WSER50 to accommodate these requirements.

Torque-Stop Functionality

A major feature of the Alpha WSER50 30/17 No Molex is its torque-stop function.

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

At the lower position, torque stop can also be used to help tension the awning fabric.

A conventional electronic top limit can still be programmed normally, with torque-stop functionality operating in conjunction with that limit.

This gives installers flexibility when configuring compatible external straight-drop systems.

30Nm Torque and 17 RPM

The Alpha WSER50 30/17 No Molex delivers:

30Nm rated torque
17 rpm output speed

This provides substantial torque for compatible external awnings, roller blinds and roller shutters while maintaining controlled operation.

Correct motor selection should always take into account the complete installation, including dimensions, weight, tube configuration and application.

Built-In Radio Receiver

The motor incorporates a built-in radio receiver, allowing wireless operation with compatible Alpha radio controls without requiring a separate external receiver.

An external antenna forms part of the motor’s integrated radio-control system.

The Alpha WSER50 30/17 No Molex remains permanently powered from a 240V electrical supply while providing the convenience of remote-control operation.

Electronic Limit Switch

The motor uses an electronic limit switch rather than conventional mechanical limit adjustment.

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

Once configured, these provide repeatable stopping positions during normal operation.

Wireless Limit Setting

Alpha specifies wireless limit setting for the Alpha WSER50 30/17 No Molex.

This allows its electronic stopping positions to be configured wirelessly using compatible Alpha control equipment.

Wireless limit setting can make setup and adjustment considerably more convenient once the tubular motor has been installed inside the awning, blind or shutter system.

Sun/Wind Sensor Compatibility

Alpha specifically states that its WSER50 Universal motors are suitable for use with:

Alpha RS001 Sun/Wind Sensor

Alpha RS002 Sun/Wind Sensor

These should be internally linked to their corresponding Frontline Supply product pages.

Weather-sensor integration is particularly useful for external awnings, where changing wind conditions can potentially place substantial loads on an extended system.

Sensor Heartbeat Protection

The WSER50 range incorporates an additional protective function when used with compatible Alpha Sun/Wind Sensors.

Alpha states 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 a signal from the sensor for approximately 30 minutes, it automatically raises the awning.

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

This provides protection against both detected weather conditions and potential loss of communication with the weather sensor.

No Molex Version

This product is specifically the No Molex version of the WSER50 30/17.

Alpha identifies it separately with product code:

WSER50NM 30/17

Because Alpha also offers another WSER50 30/17 variant, customers replacing an existing motor should confirm that the No Molex version is appropriate for their installation before ordering.

Keeping this distinction clear is particularly important when purchasing a replacement motor.

45mm Tubular Motor

The Alpha WSER50 30/17 No Molex uses a 45mm diameter tubular motor body.

Its overall length is 570mm, with a net weight of approximately 2.45kg.

The motor carries an IP44 protection rating and has an unlimited electronic turn specification.

240V Wired Operation

The Alpha WSER50 series is a wired 240V motor range.

It should not be confused with the rechargeable Alpha WSERD motors.

WSER motors receive mains power while incorporating a built-in radio receiver for wireless control.

This provides the convenience of remote operation without relying on a rechargeable motor battery.
