This range of precision high voltage modules has outputs that provide a low ripple, high stability source of high voltage for photomultiplier tubes, electron gun, nuclear and other applications. Control of the output voltage is by internal potentiometer, external potentiometer or by external 10 volt analogue control voltage. The units are pin compatible with the medium stability KS and 100 watt HW ranges.

All units are short circuit proof and use proven linear regulator techniques to drive a high frequency FET oscillator and ferrite high voltage step-up transformer. The power supplies are constructed from conservatively rated components with the reliability further enhanced by information gained from many years of field operation.

Positive, negative and electrically reversible outputs are available at voltages from 1kV to 60kV. The reversible HPR version has a latched output which can only be changed when the output is set to zero.

Electrical Specification
Input voltage: 24 volt d.c. ±10% at less than 1A (reversible units 1.3A). Negative input terminal common to HV earth return.
Output Voltage: See separate tables for fixed and reversible polarity units.
Line Regulation: Less than 10ppm of maximum voltage for input changes of 1 volt.
Load regulation: Less than 10ppm for load changes from 100uA to maximum. (Measured at maximum voltage).
Overload Protection: Flashover and short circuit proof. Re-entrant current limit.
Temperature co-efficient: 25ppm/°C or better (except HP60P & HP60N 150ppm/ °C).
Drift (except HP60): Typically 0.01% per hour Measured at constant input voltage, 0.02% per 8 hours load current & ambient temperature after 1 hour warm up.
Control: INTERNAL potentiometer. EXTERNAL potentiometer or 10V analogue signal. (0 to +10V gives zero to maximum output, tolerance +/-2%). Input impedance > 100Kohm.
Readout: Voltage monitor 0 to +10V represents zero to maximum output, tolerance ±2% (Source resistance 10 kohm). Current Monitor (optional on all units).
Note- simple current monitor includes the internally used feedback current. Precision current monitor removes this current to give a true reading (only available on HP10P & N, HP20P & N & HP30P & N).
Operating Temperature: 0 °C to +50°C
Storage Temperature: -35°C to +85°C.
R.F.I.: Steel case for low radiated magnetic field.
Synchronisation: Oscillator frequency can be locked to a suitable external frequency.
Mechanical Specification
Size: See tables
Fixings: HP1P & N, HP2.5P & N, HP5P & N, HP10P & N have M4 studs. All other units have mounting holes.
Output: By 0.5 meter screened cable (HP20, HP30 & HP60 1 meter).
N.B. Reducing the cable length may increase the ripple voltage.
Input Connector: Molex 10 pin (reversible units 12 pin), mating connector supplied.
