A1535

The power supplies of the A1535 family house 24 or 12 independent high voltage channels. The A1535 is available in different versions equipped with SHV or with Radiall Multipin connector:

Radiall Multipin connector:

– Single width (5 TE wide), 24 channel (Mod. A1535)

SHV connector:

– Single width (5 TE wide),12 channels (Mod. A1535D) NEW
– Double width (10 TE wide), 24 channels (Mod. A1535S)

The channels share a common floating return, which allows on-detector grounding, reducing the noise level. The output voltage range is 0 ÷ 3.5 kV, with 500 mV set and monitor resolution. The maximum output current is 3 mA, with 500 nA current set and monitor resolution.

The board is available with either positive or negative output polarity. Mixed version with 6/12 positive and 6/12 negative channels are also available (only with SHV connectors).

The boards are 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 modules to work as current generator. The maximum output voltage can be set through a potentiometer to a value which is common to all channels and can be read out via software. Channel can be enabled or disabled through the Interlock logic. 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).
For boards with Radiall 52 pin connector are available the following accessories:

• Mate cable connector (Mod. A996) and relevant insertion/extraction tool (Mod. A995)

• 24 Channel Multipin Radiall to SHV Adapter (Mod. A647 – R647)
