HV outputs are delivered through SHV connectors.
“Mixed” versions have two positive and two negative
channels.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel with 1
V/s steps. The module features 16bit ISET/IMON resolution. Optionally, the modules can be ordered with
current monitor resolution extended by 10x in a Lower range (selectable via software).
Safety features include:
•
OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the programmed
value
•
OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit, it is
turned off
•
Channels can be enabled or disabled through the Interlock logic
•
Channels individually enabled via front panel jumpers (passive or active mode available)
Functional parameters can be programmed and monitored via USB and Ethernet (external PC required),
supported OS: Windows 7 or later; Linux kernel Rel. 2.4 or later.
