For applications requiring a DC power converter that supplies up to 75W of power, Tri-M offers the HE104-75W. It is ideal for use on 12VDC and 24VDC mobile applications where power from a DC source (input) needs to be converted (output) to match the applications power requirements - generally an embedded computer.

Efficiency of the HE is over 90% - the higher efficiency means less heat is generated - and it is designed to operate in extended temperature applications where temperatures can be between -40°C and +85°C.

Input voltage spikes that go beyond the input voltage window (9VDC to 40VDC) are managed through transient suppressors that restrict the input voltage, while maintaining normal output power operation.

The HE104-75W is designed to minimize any generated noise or interference, allowing it to be used for airborne or ground vehicles that encounter EMI or RFI.
