A1526 - 6 Ch 15 kV Common Floating Return HV Board

Send this page

The Mod. A1526 is a double width board that houses 6 HV channels, available with either positive or negative polarity. The channels share a common floating return, which allows on-detector grounding reducing the noise level. The output voltage can be programmed and monitored in the 0 ÷ 15 kV range with 1 V resolution. The current full scale can be fixed via internal jumpers either at 100 µA or at 1 mA.
The board is provided with both current and voltage protections. If overcurrent occurs, the relevant channel can be programmed either to turn off after a programmable trip time or to keep on providing the maximum allowed current: this particular feature allows the module to work as current generator.
The maximum output voltage can be fixed, through a potentiometer located on the front panel, at the same common value for all the board channels and this value can be read out via software.
A global enable/disable connector allows to disable the channels when it is not terminated on 50 Ohm.
The HV Ramp-Up and Ramp-Down rates may be selected independently for each channel in the 1 ÷ 500 V/s range (1 V/s step).
The board features the CPE HV output connectors and the relevant coaxial cable connectors (Mod. A997) are also available.
