INTRODUCTION
A 50-Watt Power Supply Module (Figure 18-1a) is used to supply regulated dc power to the RFL 9785
System. The power supply provides four regulated dc outputs: +5, +15, -15 and +12 volts. All outputs
have overvoltage protection and short circuit protection. A Power Supply I/O Module (Figure 18-1b) is
used to provide input power connections to the RFL 9785 chassis, and contains the power supply
ON/OFF switch and an input fuse. Refer to paragraph 18.2 for more information on the RFL 9785
power supply module. Refer to paragraph 18.3 for more information on the RFL 9785 power supply
I/O module.
