ProTek Devices Intros Extended Pulse TVS for Circuit Protection in Heavy Duty Motors

PNH1275 and PHN1275B

The New Military-Grade High-Energy Extended Pulse TVS Devices Also Protect Against Long Duration Switching Transient Threats in Generators, Base Stations, and More.

ProTek Devices has introduced a high-energy extended pulse transient voltage suppressor module ideal for heavy duty remote DC power supply, base station and microwave protection, military-grade power bus, and other similar circuit protection applications.

The two modules from the company are the unidirectional PNH1275 and bi-directional PNH1275B. Generally, they are high power TVS devices designed to provide protection against long duration switching transient threats, like in heavy duty motors, generators, or where DC power is being switched on and off at frequent intervals.

These new ProTek Devices modules are compliant with the standards MIL-STD-1275, MIL-STD-1275E SEC, CE, and RTCA DO-160G. They are also compliant with IEC standards 61000-4-5 (surge): 20kA, 8/20 microseconds level 3 (LineGnd) and level 4(line-line). They boast 45,000 watts peak pulse power per line (typical = 1ms). They also feature high average (DC) power dissipation high heat dissipation capability. Each device is 100 percent tested.
