What is a Kilovac high voltage relay?

The sealed designs in KILOVAC high voltage relays incorporate innovative, proprietary technology to achieve high levels of performance. TE Connectivity KILOVAC high voltage relays are used extensively in aerospace, space, subsea and military applications, and various ground-based applications.

What is a high voltage relay?

High voltage relays are used in many technical devices that require voltages that go up to 10,000 V and currents up to 30 A. Unlike conventional relays, high voltage relay coils are located outside the vacuum and further away from the contacts. High voltage relays offer low and stable contact resistance over the part life cycle.

What is a DC overload relay?

These overload relays are engineered to interrupt DC loads while providing high shock and vibration resistance and the capacity to withstand a wide range of extreme temperatures. While operating with the same principles as electromechanical relays, these have features that support use in high voltage applications.

How Hongfa high voltage DC relay works?

Hongfa High Voltage DC relay (DC contactor) mainly adopts ceramic brazing seal structure, hydrogen-based protective gas, and utilizes the principle of magnetic blowing to extinguish the arc, which quickly solves the arc problem and realizes high voltage safe breaking.
