Overview
The CAEN Mod. A1550 houses 12 or 24 independent high voltage channels and is available in different versions equipped with SHV or with Radiall Multipin connector.

Radiall multipin connector
Single width (5 TE wide), 24 channel for Mod. A1550 |
|
SHV connector
Single width (5 TE wide), 12 channels for Mod.A1550D |
Consult our connectors reference page for technical information.
The channels share a common floating return, which allows on-detector grounding, reducing the noise level. The output voltage range is 0 ÷ 5 kV, with 500 mV set and monitor resolution. The maximum output current is 1 mA, with 100 nA current set and monitor resolution. The board is available with either positive or negative output polarity. 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).
Safety features allows the module to perform as a current generator and includes:
| Channels | can be enabled or disabled through the Global Interlock logic. |
| Remote Enable/Disable | front panel independent contacts available for all channels. |
| Overvoltage and Undervoltage warning | when the output voltage differs from the programmed value. |
| Overcurrent detection | when a channel attempts to exceed the programmed current limit, it signalled to be in “overcurrent” and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator. |
| Hardware VMAX | maximum output voltage can be set via front panel potentiometer, at the same common value for all the board channels. VMAX value can be read out via software. |
| Safety Board Interlock | this protection disables the HV generation when the HV outputs are not connected to their loads (only for Multipin Connector versions). |
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 Radiall Multipin to SHV Adapter (Mod. A647 – R647).
