Direct Current (DC) Surge Protection Devices

ProS DC Series
The Protec ProS DC series of surge protective device offers the best combined method of transient protection. This series offers Frequency Responsive Circuitry FRC protection which tracks and clamps transients on sine wave resulting in lower let-through voltages and a greater level of protection. These devices are intended for a single 12, 24, 48, 75, 95, 110, 130, 200VDC circuit application at locations feeding sensitive / critical equipment. All models are related with a robust 10kA per mode surge current rating. The PTS-DC series is designed as a stand alone device that requires no special external enclosure. Most voltage are available with either wired or terminal connections.
