PSU320-24
Input:100~240VAC 1.2A 50/60Hz
Output:27.6VDC 2A (MAX.48W)
Charge:27.6VDC 0.25A (MAX.6W)
Battery Charger (Not included):
- Battery charger output is protected by polyswitch PPTC fuse to prevent
reverse polarity, short circuit, and low voltage.
Operation Instructions:
Please refer to the wiring diagram on the left. When the emergency signal input
(JW1, JW2) is triggered, the relay contacts will switch from NC to NO, cutting
power to the electrified lock, and simultaneously the buzzer will sound.
It is suggested to connect with fail-safe electromagnetic lock.
