The DT547x is a new CAEN Power Supply Family providing a Single High Voltage channel in a small size Desktop form factor. The unit is powered and controlled by any Laptop/PC USB 2.0 port and this make it a really portable and practical solution for testing and educational needs.

A dedicated LabVIEW based Control Software allows for an easy set and monitor of the High Voltage parameters. The High Voltage output is delivered through SHV connector

Three versions are available spanning from 500 V to 5 kV and from 200 µA to 1 mA, (1 W max) meeting the needs of a wide range of applications. Each unit is provided with Imon Zoom. This feature enhances the Current monitoring, increasing the resolution of a x10 factor according to the specific model. The HV output Ramp-Up and Ramp-Down rates can be set independently in the range 1÷500 V/s in 1 V/s steps (1÷100 V/s for DT5472).

Safety features
arrow Channel can be enabled or disabled through the front panel manual switch or via Interlock logic.
arrow Overvoltage and Undervoltage warning when the output voltage differs from the programmed value.
arrow Overcurrent detection: when a channel attempts to exceed the programmed current limit, it signaled 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.
arrow Hardware VMAX: maximum output voltage can be set via front panel potentiometer. VMAX value can be read out via software.

DT547x models features:
arrow LabVIEW Instrument Driver
arrow DT547x Control software: LabVIEW Control software with Logging Capability

DT547x Control software allows to set and monitor, through a Graphical User Interface, all the unit's functional parameters.

When DT547x Control Software runs, it creates a data-log file that records the changes of the monitoring parameters (Date, Vmon, Imon, Status).
