General description
Overview
Fig. 1: Mod. 1419 series
The Mod. N1419 provides 4 independent High Voltage channels in a single width NIM mechanics. Two and one
channel versions (N1419A and N1419B) are also available.
Each channel can provide a ±500V / 200 µA max output.
Channels have common floating return (common return insulated from the crate ground); HV outputs are delivered
through SHV connectors.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the range
1÷50 V/s in 1 V/s steps.
Safety features include:
•
OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the programmed value by
more than 2% of set value (minimum 1V).
•
Programmable VMAX protection limit
•
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
•
Channels can be enabled or disabled individually through the Interlock logic.
Module control can take place either locally, assisted by a Graphic color display or remotely, via USB, RS232 or
RS485; the RS485 port allows to build a N1419s’ daisy chain network (up to 32 modules); in this case the SW1470
Control Software is necessary (see download section on www.caen.it).
The Mod. A1480 is an optional DC Input Power Equalizer which allows to use a different input power distribution on
the N147x modules.
