Product Overview
LKSR 25-NP is a LKSR series current transducer for the electronic measurement of current: DC, AC, pulsed, with galvanic separation between the primary and the secondary circuit. Applications include AC variable speed and servo motor drives, static converters for DC motor drives, battery supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS) and power supplies for welding applications, solar inverters.
- IEC 61800-5-1: 2007, IEC 62109-1: 2010, IEC 62477-1: 2012, UL 508:2013 standards
- Closed loop multi-range current transducer, voltage output
- Unipolar supply voltage, compact design for PCB mounting
- Very low offset drift, very good du/dt immunity
- CKSR footprint compatible
- Reference pin with two modes: Ref IN and Ref OUT
- Extended measuring range for unipolar measurement
- Primary nominal RMS current is 25A typ at TA = 25°C, UC = +5V, NP = 1 turn, RL = 10kohm
- Frequency bandwidth (±3 dB) is 300kHz min at TA = 25°C, UC = +5V, NP = 1 turn, RL = 1kohm
- Ambient operating temperature range from -40 to 105°C
