Spellman’s Bertan brand of PMT modular high voltage

500V TO 7.5KV @ 1.9 TO 4 WATTS

• LOW COST MODULAR DESIGN

• EXCELLENT STABILITY & REGULATION

• LOW NOISE & RIPPLE

• ARC & SHORT CIRCUIT PROTECTED

• CE LISTED, UL RECOGNIZED

power supplies offer well regulated, fixed polarity outputs

up to 7.5kV, which operate off a low voltage DC input

voltage. These fully enclosed modules are specifically

designed with proprietary linear power conversion techniques

to provide exceptionally low ripple and noise.

The PMT is ideal for precision applications including:

photomultiplier tubes, solid state detectors and

ultrasonic transducers.

The output voltage can be controlled by either a local

internal potentiometer or by a customer provided ground

referenced signal for remote operation. Additionally a

ground referenced output voltage monitor signal is

provided. The PMT can be powered from either a single

positive voltage source or a split ± voltage source,

providing application flexibility.

TYPICAL APPLICATIONS

Photomultiplier tubes

Ultrasonic transducers

Solid state detectors
