4.2 POWER SWITCHING, CONDITIONING, DISTRIBUTION
Refer to schematic 8-7 in Section 8.
4.2.1 Input Power
The VersaPulse PowerSuite operates off of 200, 208 or 230 VAC ±10% @ 30A (32A for 100W Holmium) 50/60
Hz line voltage. The main circuit breaker is rated at 32 amps for 200, 208 or 230 VAC operation. The mains are
wired into the circuit breaker. From the circuit breaker, the two mains run through the line filter and to TB1 on
the AC Control PCB. A surge protection device SRG1 is connected across the mains at J42. With the mains
connected to the AC Control PCB, power is directed in paralled to the following areas of the AC Control PCB:
• 24 VAC Interlock Transformer (T2).
• Start/Run/Stop Circuit.
• Through either softstart resistors, R1 & R2 or main contactor K4.
4.2.2 Power Distribution
All power from the main isolation transformer secondary is directed in parallel through the fuses (except to
the high voltage power supply), then to the individual loads. The loads consist of the following:
• F3 - High voltage power supply (HVPS) auxilliary transformer.
• F5 - The water pump motor.
• F6 - A DC low voltage power supply (LVPS) for the operation of the microprocessor, LCD
color display and all other electromechanical devices.
• F7 - Fan Speed Controller PCB and fan motor.
