Load (Amp DC) = 0.3 Amp = 20 hours = Continuous load Load (Amp DC) = 1 Amp = 6 hours = Continuous load Load (Amp DC) = 2 Amp = 3 hours = Continuous load Load (Amp DC) = 4 Amp = 50 minutes = Continuous load Load (Amp DC) = 16 Amp inrush = 16.5 hours = 200 cycles at 5 minute interval for EL devices
Verify 120VAC green light is present on top left side of PS914 mother board. Ensure mother board DC voltage jumper is securely set for 24VDC. At DC output terminals on lower right of mother board, check for red light and meter 24VDC output. With device and access control wires attached to option board per the instructions, provide input signal (e.g., card swipe) to power supply, then verify 24VDC at power supply option board output terminal. If 24VDC is not present, jumper the input terminals on option board (as a test) to bypass possible defective input product. If power supply DC light goes out and fuse resets, there may be an overload due to a short in the wiring, inadequate wire gauge, defective pulse width module (PWM) as seen here:
