DESCRIPTION
Input Current:
400mA max.
The Series PMM4 is a range of versatile high voltage power supply
modules which have extremely low output ripple and are directly
compatible with industry standard PMT supplies.
Output Polarity:
Positive or negative to order.
Available with +24V DC input (full input range +23V DC to +30V DC)
or ±15V DC input (full input range ±12V DC to ±18V DC), these units
allow control of the output voltage by voltage or potentiometer. Output
voltage monitoring is also provided.
The modules are designed for incorporation as component power
supplies for applications such as photomultipliers, solid state
detectors, piezo crystal devices, ultrasonic transducers, microchannel
plates, spectroscopy, scintillation counters and channel electron
multipliers.
SPECIFICATION
Voltage Load Regulation:
Less than 0.001% change in output voltage for 0 to 100% load change.
Ripple:
2mV to 5mV depending on model (see table).
Voltage Control:
Voltage Demand:t 0 to 9V for 0V to max output voltage.
Input Impedance:t Greater than 100kΩ.
Using voltage control:
C
onnect demand voltage to pin 8 with 0V on pin 7 (pin 12 on units with
Option 1).
Output Power:
4W max at full rated output voltage and current.
Output Voltage:
10V-500V to 10V-2kV max depending on model (see table).
Output Current:
2mA to 8mA max depending on model (see table).
Input Voltage Range:
+23V to +30V DC as standard.
Choose order Option 1 for ±12V to ±18V DC.
Line Regulation:
Less than 0.001% for a 0.3V change in input voltage.
Using external potentiometer (5kΩ):
Connect clockwise terminal to pin 10, counter-clockwise terminal to
pin 7 (pin 12 on units with Option 1). Connect wiper to pin 8.
Using internal potentiometer:
Link pins 8 and 9.
Monitors:
Voltage:tt
PMM4/501: 0 to 5V ±2% for 0 to 500V output (50kΩ
output impedance).
