High Voltage Damping Resistors

The damping resistor plays an important role in suppressing the spark discharge current, damping the oscillations caused by parasitic capacitances and inductances and protecting the high voltage supply during operation.
It is connected in series between the high-voltage output of the high-voltage power supply and the load, whereby the cable length between the power supply and the damping resistor should be long compared to the cable length between the damping resistor and the load - in other words, the damping resistor should be placed as close as possible to the load.

The damping resistors of the R-B40/B80/B120-scr-M series series are completely encapsulated in an aluminium housing. They have a high-voltage connection with EMC gland on each side for plugging in the high-voltage cable. The resistance value is in the one- to two-digit kilovolt range. The suitable damping resistor can be selected according to the parameter list given in the data sheet.

Resistors with significant heat generation are encapsulated in an aluminum heat sink profile, which has PG screw connections at both ends for plugging in the high voltage cable.
