Introduction

The HMSR is a new generation of high insulated Integrated Current Sensor. These product family provides a robust, compact and very accurate solution for measuring DC and AC currents in all highly demanding, switching power applications for commercial, industrial. HMSR is a micro core based open loop sensor with a reinforced insulation and overcurrent detections (user configurable and factory set). These features make the device suitable for high voltage applications requiring high precision and strong immunity against external field. The primary conductor (pins 1 and 8) has very low electrical resistance and dedicated pads designed to withstand against high surge currents such as lightning strikes. HMSR is measuring the magnetic field generated by the current flowing in the copper primary path of the device. By using a micro magnetic core, HMSR is immune to the external fields, making the device well suited for power electronic applications with high levels of disturbance. The reinforced isolation between primary (pins 1 and 8) and secondary (pins 9 to 15) offers the HSMR, a small, cost effective solution to measure high side current compared to resistive isolated solutions.
