1.2. Introduction
TDK-Lambda PHV series are state of the art precision switch mode high voltage power
supplies, designed to provide a highly stable, low ripple HV DC output for a broad range of
applications including photomultipliers, Ion sources, Insulation testing, Electron Microscopy,
and a multitude of other applications requiring precise and stable DC power.
The PHV series utilize a high frequency IGBT based inverter topology which precisely
regulates using pulse width modulation. The
unit’s high switching frequency results in low
output voltage ripple, high stability, high regulation speed, and low stored energy.
The PHV series features a fully instrumented front panel with meters displaying output
voltage and current, status LEDs, a push-button switch to turn the HV Output ON and OFF,
and precision 10-turn output current and voltage controls. The rear panel features optional
remote control, HV output, and AC input connections.
