1. General description
Overview
Fig. 1: DT54xx USB High Voltage Power Supply
The DT54xx series modules house one High Voltage Power Supply Channel (1 W max), available with
either positive or negative output polarity. The units are supplied and controlled via USB link; HV output
is delivered through SHV connector.
The HV output RAMP ‐ UP and RAMP ‐ DOWN rates may be selected independently for each channel with
1 V/s steps.
Safety features include:

OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the programmed
value (±2%)

Programmable VMAX hardware protection limit

OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit, it is
signalled to be in "overcurrent" and works as a current generator; output voltage varies in order to
keep the output current lower than the programmed value. "Overcurrent" lasting more than set value
(1 to 999 seconds) causes the channel to "trip". Output voltage will drop to zero either at the Ramp ‐
down 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 until the unit is switched off
manually.
Output can be enabled or disabled through the Interlock logic and the relevant switch. The following
versions are available:
