The uninterruptible, stabilized power supply type PWS-12-50 has been developed for safety systems requiring a nominal voltage of 12 VDC. It has a linear, built-in, safe toroidal isolating transformer.

Its maximum output load capacity is 5.5A, which is divided between the consumers connected to the output and the battery depending on the setting. Thus, it can also be used to operate consumers with lower power consumption and batteries with a larger capacity.

In the event of a power failure, the power supply immediately switches to battery mode, ensuring uninterrupted system operation. The battery can accommodate 1 12V / 18Ah battery, which must be used, because the perfect operation of the power supply is only guaranteed when used with a battery.

The power supply is designed for continuous operation, so there is no built-in mains switch, the user must provide a suitable single-phase isolating device. The electrical network must be designed in accordance with the relevant standards, so installation may only be carried out by an authorized specialist. The power supply has 3 open-collector fault signal outputs, from which a signal can be sent to the connected security system. The device may only be installed in a place corresponding to its protection, where the relative humidity is max. 90% (non-condensing) and the ambient temperature is between -10 ° C and + 40 ° C. The power supply belongs to the protection class IP00, it can only be used built-in, where adequate contact protection and natural air cooling must be ensured.

The power supply comes in a tamper-proof, closed metal plate box. The tamper protection with microswitches also triggers an alarm when the box lid is opened and removed from the wall. There is no way to install safety devices, controllers or modules in the box other than the battery.
