HAR2 / HAR12

High Voltage Amplifier Mainframe 1/2/12 Channels

HAR2 / HAR2-W / high-voltage-amplifier-mainframes

The HAR2 and HAR12 are 3U mainframes to be equipped with high precision high voltage amplifier modules HA05B2 (3U high, 6HP wide plug-in modules). The channels provide output voltages in the range of –500V to +500V at load current of ±2mA each.

The HAR2 / HAR2-W mainframes accommodate up to 2 amplifier modules. HAR2 is a table top unit, HAR2-W is a wall-mount type.

The 19"/3U HAR12S mainframe accommodates up to 12 modules. It features internal power supplies, cooling fans and a common Interlock input for all channels. This subrack may be used in rack mounted or bench top applications.

HAR12 / high-voltage-amplifier-mainframe

The HAR2 mainframe is fed by an external 24VDC ±10% power supply.
The HAR12S is supplied by mains voltage.
The mainframes contain high voltage converters to feed the HA05B2 amplifier channel modules.

Both the output voltage and the load current of each channel can be displayed on 4½ digit DVMs. A switch is provided for selection of the channel to be measured.

All output connectors are SHV type, mounted on the front panel (HAR2) or on the rear panel (HAR12S).
