NK ATCR1-420-24L-D - AC Current Transducer, ATCR Series; 500 A

• ATCR series
• AC current transducer
• Full scale range = 500 A
• Output signal = 4-20 mA
• Power supply = 24 VDC loop-powered (4-20 mA output ONLY)
• Case style = coil connected to DIN rail mounting case

ATCR Series AC Current Transducers combine a sensing coil and a True RMS signal conditioner as a matched, factory calibrated set. The ATCR Series AC Current Transducers are designed to produce an analog 4-20 mA signal proportional to AC current up to 2000 A. The coil opens to pass over the installed conductors. When connected to a controller or data logger, the sensor output is directly proportional to the primary current.

Two-Wire Loop-powered Output

AC Current Transducer Applications

Monitor Large Machines

• Monitoring resistive or inductive load to detect current.
• Industry standard 4-20 mA output for connection to PLC or data loggers.

Flexible Coil Surrounds Conductors Without Disturbing Wiring

• Install over bus bars, or single or multiple conductors easily.
• Fast response to changes in operating conditions.

AC Current Transducer Features

True RMS Output

• True RMS technology is accurate on distorted waveforms like VFD or phase angle-fired SC outputs.

Single Range

• No chance of field range selection errors.
• Eliminates zero and span pots.

Isolation

• Output is magnetically isolated from the input for safety.
• Eliminates insertion loss (voltage drop).

Compact DIN Rail Mounted Case

• Space saving 35 mm wide enclosure mounts quickly.

UL/cUL and CE Approved

• Accepted worldwide.
