Interlock loop
Interlock loop for supervising the connected load (e.g. door contacts):
The Interlock loop is connected via a 3-pin Minicon connector on the rear panel. The interlock loop must be completed through a potential free wire link/contacts.
If the interlock loop is closed, the output voltage is switchable via the ON/OFF switch with output status indicated by the green LED.
On interruption of the interlock loop, the output will shutdown via mains disconnect and the INTERLOCK EXTERNAL LED will illuminate red indicating an open interlock loop. To resume operation it is then necessary to press the RESET button.
The RESET button and status LEDs are located on the front panel.
Available for series:
▶ HCP
▶ HCK
▶ MCA
▶MCP
▶ NTN
▶ NLN
▶ HCB
Notes:
Please note this is not suitable for personal safety protection.
Optional control via digital interface: The RESET command can be sent via the remote interface and used to switch the device ON again.
Interlock loop for Programmable Logic Controller (PLC):
Interlock operation and reset are connected via the 9 pin D-sub connector on the rear panel.
A live output is indicated by the LED showing green.
An open interlock loop is indicated by the LED showing red and the HV output is switched off.
Available for series:
▶ HCP
▶ HCK
▶ MCA
▶ MCP
▶ NTN
▶ NLN
Notes:
Please note this is not suitable for personal safety protection.
Arc detection
Sensitivity level setting optionally with shut down.
Optimized arc (flashover) protection
Protection of the device in the event of a short circuit by adapting the dielectric strength of the output capacitors to a higher externally applied voltage.
Available for series:
▶ HCP
Arc sensor
Monitoring for over-current/high voltage arc with indication, shut down or arc counter.
Different versions are available:
Version 1
The arc detection isolates the HV output, indicated by the red LED. The sensitivity level is adjusted by the potentiometer. The isolated HV output can be reactivated using the RESET button.
Available for series:
▶ HCP
▶ MCP
Version 2
The arc detection isolates the HV output, indicated by the red LED, for an adjustable time range (0 to 10ms) controlled by the potentiometer. The function can be switched off via the detection toggle switch.
Available for series:
▶ HCP
▶ MCP
Arc mode & arc counter
Arcs are detected and counted. The HV output is isolated when the set counter value is reached.
The number of arcs are shown on the display for 1 minute. During this time, the device can output a message via an optional interface. The counter reading can be reset to 00 at any time using the RESET button. The arc counter can be switched off.
Arc mode has an adjustable delay and ramp function. Arc delay sets the time range (50ms to 500ms) after which the HV output is isolated following the flashover. The arc ramp potentiometer sets the time (0.4s to 4s) for the HV output to reach its full setpoint, following isolation triggered by a flashover event. Following the delay time, arc ramp increases the output from zero to the predefined voltage.
Available for series:
▶ HCP
Power regulation
In addition to voltage and current control, the output power can be controlled. The control mode gives priority to the lowest value setting. The power output can be set between zero and the rated device power using the power regulation potentiometer. The digital meter indicates the output power delivered, reading accuracy is approximately 2% of final value. The green LED illuminates once the set power is reached.
Power regulation with display and adjustment
Available for series:
▶ HCP
▶ MCP
Adjustable overcurrent trip
Overcurrent trip with RESET
The overcurrent trip isolates the output when the current limit is reached, indicated by the red LED, and is restored via the RESET button. The value of the current limit is set using the current setting potentiometer.
Available for series:
▶ HCP
▶MCP
Overcurrent trip switchable with RESET
The overcurrent trip isolates the output when the current limit is reached, indicated by the red LED, and is restored via the RESET button. The value of the current limit is set using the current setting potentiometer. This function is selectable via the ON/OFF switch.
Available for series:
▶ HCP
▶ MCP
▶ MCA
Notes:
Optional control via interface:
The corresponding commands and the message also work via the interface.
Overcurrent trip switchable

▶ HCK
▶ MCP
▶ MCA
▶ NTN
Electronic slew rate control
The slew rate control adjusts the time for the voltage or current to rise from zero to the setpoint and vice versa. The ramp time for a change in current can only be adjusted with a tool. Each setpoint change (on the front panel or via the interface) is determined by the slew rate setting.
Available for series:
▶ MCP

Hardware slew rate control
The duration of the slew rate for a change in current can be set via the potentiometers or via the digital interface option.
Available for series:
