Filtering

A perfect match for demanding applications

On-systems supplies a range of surge protection devices (SPDs) and modules to deliver a high level of protection from transient overvoltage. Our Cobra range consists of innovative, compact modules for the continuation of downstream DC-DC converters in vehicle, mobile or avionic applications. From 7A up to 20A, our modules offer a wide range of benefits:

  • Well suited for seamless integration into military systems
  • Compact with a low profile
  • PCB mounted
  • Fully compliant surge and transient protection module

Exceptional protection from disastrous failures

Our broad range of filtering modules offer additional protection from catastrophic failures and fire hazards, even under the extreme circumstances of sustained overvoltage situations. When an SPD comes to the end of its working life, it should not compromise the safety of equipment or applications. We’re committed to preventing failure due to end-of-life or continuous overvoltage faults, whilst we can deliver an accurate indication of when the SPD module needs to be replaced.

Our models not only protect the system against high-energy disturbances on DC supply lines, but also defend switching overvoltages, inductive loads, and the field supply against transient overvoltages. Proven across the globe, our pioneering SPDs are regularly supplied to Europe, the Americas, Asia, Australia and South Africa.
