Lab Power Supply Assembly
Lab Power Supply Assembly
The system power supply shall be pre-installed into the back box assembly. It shall convert the AC voltage supply to the alarm into two voltages: 5 VDC (regulated) required by the microprocessor hardware and 12 VDC (unregulated) required by the buzzer and LEDs.
  • Efficiency: 70% Min. Full Load 120 VAC
  • Overvoltage Protection: +5 V exceeds 115%-135% causes shutdown, automatic recovery
  • Overload Protection: All outputs protected against short circuit conditions, automatic recovery
  • Temperature Coefficient: 0.02%/oC, all outputs
  • Temperature Range (Operational): 0 to 50°C at rated power. Derates linearly to 50% power at 70°C
  • Temperature Range (Storage): -20°C to 85°C
