Overview
The CAEN Mod. DT1415ET (HiVolta) provides 8 independent high voltage channels in a desktop package (110/220 V AC powered). Each channel delivers up to 1 kV and 1 mA, with a maximum output power of 0.6 W.
Each channel can be operated with either positive or negative polarity, independently of the others. The channels have independent floating returns, insulated from one another up to 5 kV (full floating channels). Each channel provides one connector for the positive output and two “bridged” connectors for the negative one, allowing two or more adjacent channels to be “stacked”. The HV outputs are delivered through Radiall R317580 SHV coaxial connectors; for further technical information, consult our connectors reference page.
The module can be controlled locally, through a 2.8″ color touchscreen LCD display, or remotely via USB or Ethernet. A complete set of software tools is available to control the unit, and users can freely download low-level libraries, the LabVIEW driver and graphical application software.
The module also includes dedicated safety features that allow it to operate as a current generator. An overvoltage and undervoltage warning is issued when the output voltage differs from the programmed value by more than ±1% ±2 V of the set value. When a channel attempts to exceed its programmed current limit (Iset), it is flagged as being in “overcurrent” and enters TRIP status: the output current is adjusted to keep it below the programmed limit for a programmable TRIP time, after which the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves as a current generator. A hardware VMAX limit can be set via a front panel potentiometer to the same common value for all channels of the board, and its value can be read out via software. Finally, a common safety board interlock logic enables or disables the channels, while individual input signals provide a kill function for each channel.

Trip |
Max. time an “overcurrent” is allowed to last (seconds). A channel in “overcurrent” works as a current generator; output voltage varies to keep the output current lower than the programmed value. “Overcurrent” lasting more than set value, causes the channel to “trip”. Output voltage will drop to zero at the Ramp-down rate; in this case the channel is put in the off state. If trip= INFINITE, “overcurrent” lasts indefinitely. TRIP range: 0 ÷ 999.9 s; 1000 s = Infinite. Step = 0.1 s |
|
“Zero” current |
Zero Current Detect channel parameter allows to sample the present IMon value; this value (IMonZero) can be then subtracted via the Zero Current Adjust parameter ENABLE, from the monitored current (IMon), to compensate the current offset; if ZCAdjust = Enabled, then the IMon value is compensated. After the IMonZero value is sampled, Zero Current Detect, returns to Off. Allowed IMonZero values are from 0 to full scale. If Zero Current Adjust is DISABLED, the IMonZero compensation is neglected. |
