Electro Cam PL-1746 Series - Manual (Page 135)

9-2 Specifications & Factory Defaults
Electrical (The PL-1746 controller is UL and UL-C listed)
Input Power: 20-30 VDC. Keypad/display is powered from controller.
Backplane Power: 5 VDC @ 500 mA max.
I/O Power: 20-30 VDC @ 90 mA max. plus 150 mA per PS-6400 keypad.
Certain types of power supplies employ a self protection feature called current fold back
limiting. The inrush currents of the high efficiency switching regulators may cause power
supplies to enter current limit mode. Power supplies with current fold back limiting should be
sufficient to supply three times the steady state current of the system.
Permanent Memory: EEPROM (no battery required).
