The CAEN Mod A7040 is a single width board (5 TE wide) that houses 48 independent high voltage channels.
The channels share a Common Floating Return, which is insulated from the chassis/crate ground. This feature may help to minimize problems of ground-loops. The board is available with positive or negative output polarity Channels are delivered with DB37 connectors. Consult our connectors reference page for technical information.
The output voltage range is 0 ÷ 100 V, with 0.2 mV monitor resolution. The maximum output current is 1 mA, with 2 nA monitor resolution.
Independently programmable for each channel:
|
|
Output voltage: |
|
0 ÷ 100 V |
|
Step: 2 V |
|
|
Current limit (Iset): |
|
0 ÷ 1 mA |
|
Step: 20 nA |
|
|
V Ramp up/down: |
|
1 ÷ 50 V/s |
|
Step: 1 V/sec |
|
|
TRIP parameter: |
|
0 ÷ 999.9 s; 1000 s = Infinite |
|
Step: 0.1 s |
Safety features include:
-
Channels: can be enabled or disabled through the Global Interlock logic.
-
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 signals an “overcurrent” condition and enters TRIP status. The output voltage is adjusted to keep the current below the programmed limit for a programmable TRIP time, after which the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves as a current source.
-
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 allows to disable the primary HV generation when the HV outputs are not connected to their loads.
CAEN provides a complete software range to control, monitor and configure its Power Supply products.

Universal Multichannel Power Supply Systems (Mainframes)
Universal Multichannel Power Supply Systems, or Mainframes, are modular systems designed to house and control High Voltage (HV) and Low Voltage (LV) boards, providing power for particle detectors and their associated electronics in standard 19” racks. CAEN offers four mainframe versions:
-
SY4527: A large experimental system. This 19” wide / 8U high mainframe can house up to 16 HV/LV boards. It offers a power output from 600W up to a maximum of 4200W, depending on installed Power Supply Units and display type. Local control is optionally available via a 10.4” or 5.7” LCD Touchscreen.
-
SY5527: A more compact laboratory version. This 19” wide / 4U high mainframe can house up to 6 HV/LV boards. Its power output ranges from 600W up to a maximum of 1800W, depending on Power Supply Units. Optional local control is available via a 5.7” LCD Touchscreen.
-
SY4527LC: A cost-effective alternative with a shorter depth (~20cm compared to standard SYx527). This 19” wide / 8U high mainframe houses up to 10 boards and includes a 600W power supply. It does not include an LCD display. It is fully compatible with SY4527 and SY5527 boards.
-
SY5527LC: Also a cost-effective, shorter depth alternative (~20cm compared to standard SYx527). This 19” wide / 4U high mainframe houses up to 4 boards and includes a 400W power supply. It does not include an LCD display. It is fully compatible with SY4527 and SY5527 boards.
All systems offer modular design for simplified upgrades and maintenance and can be controlled remotely via Ethernet.

Ramp Up / Ramp Down |
Max. time an “overcurrent” is allowed to last (seconds); common to all channels. A channel in “overcurrent” works as a current generator; output voltage varies in order to keep output current lower than the programmed value. “Overcurrent” lasting more than set value, causes the channel to “trip”. Output voltage will drop to zero either at Rampdown rate or at the fastest available rate, depending on Power Down setting; in both cases the channel is put in the off state. If trip= INFINITE, “overcurrent” lasts indefinitely. TRIP range: 0 ÷ 999.9 s; 1000 s = Infinite. Step = 0.1 s |
