RPC-40L8A4 Series; Quick Start Guide
2. Back Panel Components
As shown in Figure 1 above, the RPC-40L8A4 Back Panel includes the following:
Power Input:
Two 40 Amp DC input Buses. The power input terminal block also
includes two mounting brackets, which are used to hold the protective cover
(not shown).
Switched Output Circuits - Bus A:
Four 10 amp DC circuits in an output terminal
fed by power input bus A. DC output voltages are as follows:
• RPC-40L8A4-48 = ± 48 V DC, 10 Amps
• RPC-40L8A4-24 = + 24 V DC, 10 Amps
• RPC-40L8A4-12 = + 12 V DC, 10 Amps
Output Circuit Fuses - Bus A:
Four 10 amp DC GMT fuses that protect circuits on
Output Bus A. Ships with 10 Amp fuses; for custom fuses, please contact WTI
Switched Output Circuits - Bus B:
Four 10 amp DC circuits in an output terminal
fed by power input bus B. Voltages for each RPC-40L8A4 model are described
under item 2 above.
Output Circuit Fuses - Bus B:
Four 10 amp DC GMT fuses that protect circuits on
Output Bus B. Ships with 10 Amp fuses; for custom fuses, please contact WTI
Optional Grounding Lug Location:
Mounting holes for optional grounding lug
for 6 gauge ground wire. For more information, please contact WTI.
Alarm Inputs:
Four alarm inputs, designed for connection to door open alarms or
other dry contacts. Each alarm input supplies 0.4 Amps of positive DC current at the
same voltage used to power the unit (± 48 V DC units p48 V DC, +24 V DC
units p24 V DC and +12 V DC units p12 V DC.)
