KOA Speer Electronic’s family of current sense resistors are available in metal plate, power shunt, thick film and wide terminal designs. KOA's wide range of sizes, power ratings, resistance values, TCR, and tolerances make them ideal for controlling the current to protect power supply circuits in applications such as automotive, industrial equipment, communications, energy and medical equipment.

The UMR-HPC series of HV power supplies (up to 30kV @ 60 to 250W) are form-fit-function high-performance modules suited for cap charging projects, such as HV fault detection (identifying insulation failure, short circuits, & ground faults in cables & equipment). UMR-HPC units provide the power & reliability necessary for these systems & provide assurance that the faults will be recognized to prevent system failures & minimize downtime.
