Surge & Transient Filter | Gresham-Transpower

Application

Intended to operate from electrically noisy supplies such as those found on vehicles, these power suppressors remove the harmful surges and spikes which could destroy DC/DC converters.

DC suppressor for military platforms, including vehicles, tracked vehicles, helicopters etc.

MIL-STD 1275A/B/C and D, MIL-STD 461E and F and DEF-STAN61-5 part 6 issue 6 compliant and protect the DC power supply by removing the harmful Over Voltage surges using circuit protection, environmental de-rating, earthing and more.

With 300W and 600W versions available. DC suppressor is an ideal and reliable choice.

Supplied in module format or incorporated into a design, we can provide you with the optimum solution.
