APS-30 S

Backup power supply

The APS-30 S switch mode power supply is designed for devices that require 12 VDC nominal voltage. The set includes: power supply, transformer, enclosure OPU-4P (with space for a 7 Ah battery) and additional accessories (tamper switches, spacers, connecting cables for transformer, wall plugs (anchors) and screws).

  • nominal output voltage (according to IEC 38): 12 V DC
  • output voltage stabilization
  • battery status control and low battery disconnect system
  • ability to work without a battery connected
  • output current:
    • operation with battery: 2,5 A / 2 A
    • operation without battery: 3 A
  • battery charging current: 0,5 A / 1 A (selectable)
  • pins enabling configuration of the power supply settings
  • 3 LEDs to indicate:
    • AC mains power supply status
    • battery status
    • battery charging
  • 2 OC outputs to indicate the following troubles:
    • AC mains power loss
    • low battery
  • acoustic signaling of troubles
  • electronic short-circuit protection of AC mains power supply circuit
  • short-circuit protection fuse for battery charging circuit (T 3,15 A)
  • electronic short-circuit and overload protection of the power output
  • tamper protection against enclosure opening and removal from mounting surface
