Overview
The power supply A2554 is a single width board (5 TE wide) that houses 8 independent Low Voltage Individual Full Floating channels, compatible with the CAEN Universal Multichannel Power Supply System (SY4527, SY5527). The A2554 is available with DB37 connector:

Consult our connectors reference page for technical information.
A2554 Individual Floating channels allow on-detector grounding, reducing the noise level. The floating channels are insulated from each other up to ±500 V. Each output channel is provided with individual remote sensing lines to compensate for the voltage drop over the connection cables.
The output voltage range is 0 ÷ 64 V, with 1 mV monitor resolution (connector and sense voltages). The maximum output current is 1.5 A with 50 μA monitor resolution. The Maximum channel power is 60 W. The Output Voltage RAMP UP and RAMP DOWN Times may be selected independently for each channel in 1 ÷ 500 V/s range (1 V/s step).
Safety features allows the module to perform as a current generator and includes:
Overvoltage detection | if a channel voltage exceeds the programmed Overvoltage threshold value (OVVThr), it is signaled to be in “overvoltage” and is switched off. |
Undervoltage detection | if a channel voltage decreases below the programmed undervoltage threshold (UNVThr) it is signaled to be in “undervoltage” and is switched off. |
Overcurrent detection | if a channel tries to draw a current larger than its programmed limit, it is signalled to be in “overcurrent”; when overcurrent is detected, 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 feature allows the module to work as current generator. |
A global enable/disable connector | allows to disable the channels and it is also possible, via front panel logic signals, to enable individually each channel (A2554A only). |
