Made in Italy
We remark that all our boards have been designed and assembled in Italy. In a challenging environment where a
competitive edge is often obtained at the cost of lower wages and declining working conditions, we proudly acknowledge
that all those who participated in the production and distribution process of our devices were reasonably paid and
worked in a safe environment (this is true for the boards marked "MADE IN ITALY", while we cannot guarantee for third-
party manufactures).

2. 803x Series Overview
The 803x power supply series provides 8 or 16 independent HV channels, whose control can take place
either locally thanks to a 2.8" Touchscreen Graphic color LCD display or remotely, via USB 2.0 or Ethernet.
The units are available in three formats: double width NIM mechanics, 19” rack module and Desktop case.
NIM and Desktop versions feature 8 channels, the 19” rack units can house either 8 or 16 channels.
5 output ranges are available (100V/10mA, 500V/10mA, 4kV/3mA, 6kV/20µA and 6kV/1mA), with either
positive or negative polarity; all units are provided also in “mixed” version, with half of the channels
positive and half negative. 100V channels are delivered through BNC connectors, other versions feature
SHV’s.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel.
Safety features include:
•OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the
programmed value by more than 2% of set value (minimum 10V).
•Programmable VMAX protection limit via front panel trimmer; common to all channels
•Programmable IMAX protection limit via front panel trimmer; common to all channels
•OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit,
it enters TRIP status, keeping the maximum allowed value for a programmable time (TRIP),
before being switched off.
•Common Interlock logic for channels enable/disable and individual inputs signal for channel Kill
function.
A complete set of Software Tools is available to control these units; the User can freely download low
level libraries, LabVIEW driver and Graphical application software.

Interlock signal
VMAX
trimmer
it allows to adjust the hardware maximum voltage VMAX common to
all the channels. Its value can be read out via software.
IMAX
trimmer
it allows to adjust the hardware maximum current IMAX common to
all the channels. Its value can be read out via software.
Alarm signal
As an Alarm condition is detected, pins 2 and 3 (- and +) are closed; the contact can be
used to switch an external device supplied by an external source, otherwise the VB and
GND references can be used to provide a TTL compatible level on pin 2 and 3.
In the first case (externally supplied device) the maximum allowed ratings are:
•Maximum voltage between + and -: 12V
•Maximum sink current across + and -: 100mA
In the latter case, to produce a TTL compatible Alarm Out, pin 3 (+) must be
connected with pin 4 (VB) and pin 1 (GND) with pin 2 (-); see the diagram:
Interlock signal
A schematic diagram of the Interlock input is shown in the figure on the
left, where the diode is part of opto-coupler stage.
Interlock means that channels are hardware disabled. The following table
explains the interlock operation:
CONFIGURATION 
INTERLOCK MODE →
UNDRIVEN
DRIVEN
leave contact open
INTERLOCK
ENABLED
voltage level (0÷1V, ~5mA current) between pin 2 (high) and pin 3 (low)
INTERLOCK
ENABLED
short circuit pin 1 with pin 2, and pin 3 with pin 4
ENABLED
INTERLOCK
voltage level (4÷6V, ~5mA current) between pin 2 (high) and pin 3 (low)
ENABLED
INTERLOCK
The front panel Interlock LED is ON when the INTERLOCK is active; as INTERLOCK is active, channels are turned off at the fastest
available rate, regardless the RAMP DOWN setting. To reset the Interlock flag, all switches must be placed on KILL and then on OFF.
