The DT55xxE is a CAEN Power Supply Family providing 4 independent High Voltage channels in a compact Desktop form factor. The units are available with either positive, negative or mixed polarity. High Voltage outputs are delivered through SHV connectors. DT55xxE units can be controlled, via USB or Ethernet, taking advantage of the new GECO2020 Control Software.Different versions are available spanning from 500 V to 6 kV and from 20 μA to 3 mA (4 W maximum), meeting the needs of a wide range of applications. A Zoom option is available for Imon. This feature enhances the current monitoring, increasing the resolution of a x10 factor (up to 10 pA). The HV output Ramp-Up and Ramp-Down rates can be independently for each channel in the range 1 ÷ 500 V/s in 1 V/s steps (1 ÷ 100 V/s for DT5519E).Safety features include:

• Overvoltage and Undervoltage warning when the output voltage differs from the programmed value (±0.5% of the set value, ±3 V)
• Programmable hardware VMAX, IMAX protection limit
• 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 of. If TRIP is set to “constant current mode”, the channel behaves like a current generator.
• Common Interlock logic for channels enable/disable and individual input signal for channel Kill function.

Available Options:

• x 10 Imon Zoom, increasing Imon resolution to 10 pA (DT5521HE).
