High Voltage Power Supplies
All outputs are current limited and short-circuit protected.
HV INHIBIT INPUT – has two modes.
•
POSITIVE POLARITY – For CANBERRA preamplifiers. Enable
condition (cold detector) is an open circuit or active high = +1.2 V to +24
V; Inhibit condition (warm detector) is –24 V to <+1.2 V or ground.
• NEGATIVE POLARITY – For preamplifiers and LN monitors, where
Enable condition (cold detector) is –24 V to <+1.2 V; Inhibit condition
(warm detector) is open circuit or active high = +1.2 V to +24 V.
With Negative polarity selected, an open input will disable the high voltage.
Individual connectors for positive (HV+) and negative (HV–) high range (1500 V)
outputs. A separate connector is provided for the ±200 V output.
