Kintamos ir/arba nuolatinės srovės keitikliai DHR-C10 ir DHR-C420 Inom&61100..1000A

The transducer for the electronic measurement of DC [&] distorted AC waveform currents, with galvanic isolation between the primary circuit (power) and the secondary circuit (measurement). True RMS 0-10V voltage output.

Features
• VFD and SCR waveforms current measurement
• True RMS output
• Panel mounting
• Eliminates insertion loss
• Isolated plastic case recognized according to UL94-V0

Advantages:
• Large aperture for cable up to Ø32mm
• High isolation between primary and secondary circuits
• Easy installation

Applications
• VFD Controlled Loads VFD output indicates how the motor and attached load are operating.
• SCR Controlled Loads Acurate measurement of phase angle fired or burst fired (time proportioned) SCRs. Current measurement gives faster response than temperature measurement.
• Switching Power Supplies and Electronic Ballasts
True RMS sensing is the most accurate way to measure power supply or ballast input power.

Warning:
Transmitters should be installed and serviced after power off. The service technician should be authorized to repair the installation of this type of equipment. Users should follow safety regulations against electric shock.
