LEM makes voltage measurement more compact

LEM announced its range of low cost and lightweight transducers dedicated to the measurement of leakage current in PV inverters. The new LDSR model is dedicated to measuring the leakage current of 300 mA nominal up to 900 mA peak at 2 KHz frequency. The sensor is mounted onto a PCB for primary and secondary connections & provides an analogue voltage output.

“LDSR satisfies the needs of PV inverters, offering a competitive price, low dimensions and complying with all regulatory standards. LDSR is also an excellent alternative to expensive fluxgate solutions due to its small footprint and simple construction. As well as ensuring safety in solar inverter installations, LEM’s LDSR product is also ideal for a range of applications that include symmetry fault detection in medium power inverters and failure detection in a range of power sources,” explains LEM.

The LDSR has been designed with an integrated primary conductor capable of 35 A on both the phase and N line. The proprietary ASIC ensures high-performance accuracy from -40 to +105°C fulfilling the requirements of the EN 61209 standard, added the company in an official statement.
