EHS Standard

(Please scroll down for EHS High Precision versions)

 

EHS modules are multichannel high voltage power supplies in MMS system (Eurocard format). With up to 32 channels each single cahnnel has an independent voltage and current control. The module is made of high-precision components such as 24 bit ADC and up to 20 bit DAC an provides comprehensive safety features.

 

 By offering different configurations, this module perfectly covers various types of applications. The EHS standard module is available in two floating versions, Common Floating Groud (CFG) and Floating Ground (FG).

EHS High Precision

 

EHS High Precision modules are multichannel high voltage power supplies in MMS system (Eurocard format) with best stability, temperature coefficients and very low ripple and noise characteristics. With up to 16 channels each single channel has an independent voltage and current control. Compared to a standard module the High Precision EHS is equipped with a second current measurement range to precisely meter low currents. Switching of measurements ranges is done automatically. 

 

 By offering different configurations, this module perfectly covers various types of applications. The EHS High Precision module is available in two floating versions, Common Floating Groud (CFG) and Floating Ground (FG).
