Product Overview
LF 310-S is a current transducer. It is used for the for the electronic measurement of DC, AC, pulsed current with galvanic separation between the primary and the secondary circuit. Applications include windmill inverters, test and measurement, substations, AC variable speed and servo motor drives, statics converters for DC motors drives, battery supplied applications, uninterruptible power supplies (UPS), switched mode power supplies (SMPS).
- Bipolar and insulated current measurement up to 500A
- Current output, closed loop (compensated) current transducer
- Panel mounting, high accuracy, very low offset drift over temperature
- 100KHz typ frequency bandwidth at (RM = 50 ohm, -3dB)
- Supply voltage range from ±11.4V to ±21V
- 0.1% typ sensitivity error, 0.25A typ secondary current
