The new EHR series represents a system capable multichannel high voltage module - equipped with advanced iseg HV generation technology - for MMS system. The EHR provides 4 HV-channels, each with an independent voltage and current control and reversible polarity. A flexible 6kV channel provides 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.

Overview of the EHR series:

• 4 channels

• Electronically switchable polarity for each channel independently

• 2 kV / 6 kV versions

• 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
