LDSR Series Current Transducers
LEM's LDSR series safety current transducers for leakage current detection
LEM's LDSR series is designed for photovoltaic (PV) applications, providing accurate measurement over three orders of magnitude and simplifying residual current measurement. The LDSR series advantages are very low offset drift temperature coefficient, high overload and insulation capability, reference pin with two modes, Ref IN and Ref OUT, and test winding.
Features
- Single supply voltage
- PCB mounting
- Voltage output
- Closed-loop (compensated) current transducer
Applications
- Symmetrical fault detection
- Failure detection in power sources
- First human contact protection of PV arrays
- Leakage current measurement in transformerless PV inverters
- LDSR 0.3-NP: 3 phases plus neutral
- Current leakage detection in stacked DC sources
- LDSR 0.3-NP: nominal current per phase measurement up to ±30 A per wire (DC or AC)
- LDSR 0.3-TP/SP1: single phase nominal current measurement up to ±35 A per wire (DC or AC)
