LEM莱姆 HAL 50-S 电流传感器
LEM HAL 50-S CURRENT TRANSDUCER
LEM
The HAL 50-S from LEM is a current transducer. It features instantaneous output, easy installation, low power consumption, small size and space saving, wide current range and high immunity to external interference. This current transducer is used for the electronic measurement of currents (DC, AC, pulsed, mixed) with galvanic separation between the primary circuit and the secondary circuit. It is mainly used in AC variable speed drives 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. Open loop hall effect measuring principle Primary nominal rms current of 50A 1% accuracy Primary current measuring range is ±150A Supply voltage of ±15V Bipolar voltage supply Secondary nominal signal of 4V Insulated plastic case recognized according to UL 94-V0 Operating temperature range from -25°C to 85°C Panel mounting Sensor Output: Voltage Supply Voltage DC Min: -15V Supply Voltage DC Max: 15V Current Measuring Range DC: -150A to 150A Current Measuring Range AC: -150A to 150A Response Time: 3µs Accuracy %: 1% Product Range: HAL 50?600S Series Frequency Max: 50 Accuracy: ± 1% SVHC: To Be Advised Find similar products grouped by common attribute
