The power supply A2551 is a single width board (5 TE wide) that houses 8 independent Low Voltage Individual Floating channels, compatible with the CAEN Universal Multichannel Power Supply System (SY4527, SY5527). The A2551 is available in different versions equipped with D-Sub 8-pin or with DB37 connector:
D-Sub 8W8 – 8 pin high current connector
Single width (5 TE wide), 8 channel
– Single width (5 TE wide),8 channels
Consult our connectors reference page for technical information
A2551 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 ÷ 8 V, with 0.2 mV monitor resolution (connector and sense voltages). The maximum output current is 12 A with 500 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 include:
- 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 (A2551A only).
