EHR
Polarity switchable High Precision HV Module
The new EHR series represents a system capable multichannel high voltage module - equipped with the finest iseg HV generation technology in MMS system (Eurocard format). The module is made of high-precision components such as 24 bit ADC and up to 20 bit DAC and provides comprehensive safety features.
The EHR provides 4 HV-channels, each with an independent voltage and current control and reversible polarity.
A flexible 6kV channel provides a maximum versatility: With three electronically switchable HV-generation modes it can supply 4 mA up to voltages of 2 kV, 3 mA up to 4 kV or 2 mA up to 6 kV. Alternatively the EHR can be equipped with cost efficient 2kV/6mA fixed channels.
By offering different configurations and options this module perfectly covers various types of applications such as detector supply, experimental setup or lab use.
- 4 channels
- Electronically switchable polarity for each channel independently
- 2 kV / 6 kV versions
- 6 kV channel with electronical switchable modes: up to 2 kV/4 mA, 4 kV/3 mA or 6 kV/2 mA
- High precision / very low ripple and noise
- Second current measurement range 20 µA for high precision version
- Voltage and current control per channel
- Hardware voltage and current limits
