The ELK-P212S is a Supervised Remote Power Supply / Battery Charger, providing 12V DC output with up to 2 Amps of total current. It supervises the AC Power Input as well as the rechargeable Battery, and can report abnormal conditions back to an ELKM1 Control over the RS485 four (4) wire data bus.
It also features relay outputs for AC and Low Battery to allow "stand-alone" operation with other Controls (Security, Access, CCTV products, etc.). Power from the P212S can be used to increase the capacity of a control, or to remotely power devices such as motion detectors, keypads, zone expanders, sirens, annunciators, etc.
The P212S monitors the AC Power Input and periodically loads tests the Battery. There are two (2) sets of 12 VDC power outputs with a combined rating of 2 Amps. The outputs are protected against overcurrent by PTC self-restoring circuit protectors. A convenient On/Off switch provides the ability to quickly and easily disconnect both the AC and DC for maintenance. The P212S also includes automatic low battery disconnect circuitry to protect against battery deep discharge during an extended power outage.
