Product Description

  • DC 12V power supply
  • Electronic limit switch
  • Built-in receiver

The WSERD30B 3/20 motor has internal lithium rechargeable batteries with approximately 10-12 months of average use between charges. It can be used on blinds up to 15ft x 10ft.

This new version of our popular battery motor has a new ground-breaking coreless DC drive inside, that is much more efficient and much quieter than other battery motors.

The fittings for this motor will allow it to be used with a range of tube sizes from 30-50mm in diameter. All of the charging intelligence is taken care of inside the motor, not by a 3rd party charger. This eliminates many of the issues experienced by other brands of DC motors. The motor will indicate both when charging is required, and completed. It cannot be overcharged and it will not start to discharge when the batteries are full as other brands may do. The charger plugs directly into the motor head so there is no need for an unsightly charging cable.

  • ALDC charger required
  • (Charger comes with 13ft cable, 10ft cable also available)
