Current transducer LEM HTFS 200-P with single 5 volt power supply and high immunity to external interference
Current Transducer HTFS 200 ... 800-P
The HTFS 200-800-P is a current transducer designed for the electronic measurement of DC, AC, and pulsed currents, providing galvanic separation between the primary and secondary circuits. It features a Hall effect measuring principle, low power consumption, a single +5V power supply, and a ratiometric offset. The transducer is housed in an insulating plastic case recognized according to UL 94-V0 and is fastened by M3 nuts and screws. Its compact size, wide current rating range, and high immunity to external interference make it suitable for various industrial applications such as forklift drives, AC variable speed drives, and power supplies for welding applications.
