User's Manual Part 1

The power supply module contains a 530 watt switching power supply and an eight position
terminal block. It is configured for three output voltages +12V, -12V, and a main output
power of 10.8V. The supply is power factor corrected to .98 for optimum efficiency and
decrease in energy consumption. For safety purposes all outputs are over voltage and over
current protected. This supply will also accept input voltages from 85 to 264 volts AC, but
the power entry module must be switched to the proper input voltage setting. The terminal
block within the power supply module is protected by metal oxide varistors which protect
and prolong the life of the power supply by providing surge protection. Below is a list of
the connections on J1 which interface with other devices.
