PD21/22 – Okin

Gardhen Bilance - Dewert Okin

Return to: | Accessories |



The external PD 21 and PD22 power supplies combine space-saving design with strong performance. They can be used around the world because they automatically adapt to different national voltages. Only the corresponding pluggable mains cable with an input voltage from 100 to 240 V AC is required.

The PD21 and PD22 can be combined with all OKIN drives; this makes them ideal for a wide range of bedding and seating applications. Thanks to their electronic switched-mode power supply technology (SMPS), the external power supplies are more efficient, more compact and lighter. They deliver a constant output voltage that is independent of the input voltage. They also have very low standby current consumption (according to EU energy efficiency class VI) and comply with the Ecodesign Directive 2009/125/EC.


The PD21 and PD22 help to effectively protect persons against electric shock – because the power supply is not in the control unit, the mains voltage is not inside the furniture. This also ensures a very low electromagnetic field. Last but not least, the electronic over-current switch-off mechanism ensures that the circuit is interrupted whenever the specified current is continually exceeded.

The external power supplies also feature an NTC temperature sensor, primary fuse, overload protection and a short-circuit proof output. Optionally, the PD21 can be retrofitted with two 9-volt batteries (6LR61) to enable emergency lowering during a mains power outage.
