Ensuring success for your critical applications

Reliable, safe power supplies are needed in high voltage applications to guarantee trouble-free operation.

In high voltage power supplies the output stage is capacitive by nature, which results in stored energy. During an arc discharge, the stored energy inside the power supply is quickly dispersed through an internal limiting resistance and carries high peak currents through the load.


The high energy pulse magnitude (EMT pulse) that occurs during an arc can damage the high voltage power supply and the load, as well as potentially disrupt sensitive control and microcontroller circuitry.


Our high voltage power supplies feature arc current limiting and arc sensing circuitry to protect the load from arcing damage.

If you don’t address isolation requirements properly or make poor insulation choices, then your power supply could become destabilized. You should also ensure that moisture is not being absorbed into the device and guard against leakage currents.


Our industry-leading design and manufacturing controls ensure longevity and consistent performance in your critical applications.
