Power/Cooling Unit (PCU)

The PCU unit generates the following:
• control of the system with the necessary power-up time delays, clock rep rate signals,
charge/fire commands and Q-switch delays.
• monitoring of the 9 security loops on the front panel.
• power for state-of-the-art MOSFET switching power boards that run at a drive
frequency of 40 kHz. Current from the board charges up the storage capacitor.
• capacitance of 30 µF at 2.0 kV. In addition to energy storage for the flashlamp, the
system also provides an initial trigger pulse to ionize the gas in the flashlamps.
Structure & organization
The PCU unit is packaged very compactly. The unit is 11.25" (28.6 cm) wide 20.75" (52.7 cm) tall
and 24.5" (62.2 cm) deep. The weight of the PCU unit is 85 pounds (38.6 kg). The system is
designed to operate on ac voltages ranging from 200 to 240 V 50-60 Hz at less than 10 amps.
