PL-1746-C01 Module Specifications
Electrical (The PL-1746 controller and PS-4108 rack are both UL and UL-C listed)
Input Power: 20-30 VDC. Keypad/display is powered from controller.
Backplane Power: 5VDC @ 500 mA max.
I/O Power: 20-30 VDC, 80 mA +150 mA per keyboard + 230 mA per rack.
Example: Total = 840 mA with 2 keyboards and 2 racks.
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.
Inrush current @ 30v, 40 amps max. for 600
µ
s (2 keyboards, 2 racks).
Permanent Memory: EEPROM (no battery required).
