HV DC power supply

S1M up to 150kV Power up to 2kW

Rack mounted power supply, voltage up to 150kV and power up to 2kW, for single phase mains.

Main specification

Charging Power:

300 W, 600 W, 1200 W and 2000 W

Voltage:

up to 150kV

Polarity:

Positive, Negative, Reversible

Rise time (10-90%):

< 300 ms - better on demand

Ripple + Noise :

0.1% RMS of full voltage - better on demand

Remote interface:

0-10V analogue – see other interfaces

Based on the ZCS resonant topology, the SR1M series is a multipurpose range designed to offer the best performance in a compact design.

Dry isolated, it offers high reliability and high operational availability. No special maintenance is required.
