4.6 POWER SUPPLY MODULE
The Power Supply consists of 3 invertors with the AC inputs and DC outputs connected in parallel. Each
invertor is rated for 5 kW (50 VDC at 100 A). Total output power of the Power Supply is 15 kW (50 VDC at
300 A).
The 3-phase AC input is applied to the invertors through a 3-pole circuit breaker mounted on the front panel.
This circuit breaker also serves as the AC power switch.
The DC output of the invertors is routed through 8 circuit breakers on the front panel. There are 2 circuit
breakers for each 1.25 kW Power Amplifier module.
The DC output is also applied to the Accessory connector (J4) through a 3A circuit breaker.
Two of the AC input lines are routed to an auxiliary AC output connector (J2) on the rear panel. This output
is protected by a 5A 2-pole circuit breaker mounted on the rear panel. The auxiliary AC output is not
controlled by the front panel AC power switch. It is always present even if the front panel power switch is off.
This output is used to provide 208 VAC power to the Exciter module and the System Controller module.
