The PWS-12-20 uninterruptible, stabilized power supplies are the mount box versions of the LINTAP2-12V / 2A power supply cards. The power supply family has been developed for safety systems requiring a nominal DC voltage of 12VDC.

They are linear in operation, have a built-in, safe toroidal isolating transformer, and have a rated output load of 2A, which is the total current available to the connected electrical consumers and the battery. In the event of a power failure, the power supply immediately switches to battery mode, ensuring uninterrupted system operation.

The box can accommodate 1pc 12V / 7Ah battery. The use of this is mandatory, 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 the appropriate single-phase isolating device.

The power supply has 2 optocoupler fault outputs, from which a signal can be sent to the connected access control system in the event of a 230V mains failure or loss of output DC voltage. The device may only be installed in a location that meets its protection, where the relative humidity is max. 90% (non-condensing) and the ambient temperature is between -10 ° C and + 35 ° 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 is supplied 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.
