J&D’s New Product will be launched at the upcoming Trade Show 2015 AHR EXPO (#3741)

The New JRF-RMS series flexible Rogowski coil AC current transducer.
These exceptionally high-accuracy, 1.37” (35mm) to 19.68” (500mm) opening CTs have primary current 100A to 6,000A AC and secondary output 0-5V, 4-20mA DC, 333mV AC
The UL61010-1 recognized New JRF-RMS series for process control, status alarming or system monitoring purposes.

Simple to install and easy to retrofit it combines the benefits of a thin, flexible, Split-core Rogowski coil with a signal conditioner providing accurate, true RMS measurement, of AC current for process control, status alarming or system monitoring purposes.
The JRF-RMS has an industry standard 4-20mA, 0-5V DC output making it ideal for process control, status alarming or system monitoring purposes. Typically the JRF-RMS is used with for SCADA systems, PLCs, data loggers and protection equipment.

The JRF-RMS is available as a single channel transducer (JRF-RMS) or as a 3 Channel Version (JRF-RMS-3phase)


The New JM21X-RMS series AC or DC split-core current transducer
These exceptionally high-accuracy, 0.82” (21mm) opening CTs have primary current 5A to 250A AC or DC and secondary output 0-5V, 0-10V, 4-20mA DC.
The UL61010-1-recognized JM21X-RMS series for process control, status alarming or system monitoring purposes.
Compact and Easy installation, cost-effective of a split-core, JM21X-RMS provides accurate, true RMS measurement, of AC or DC current.

Typically the New JM21X-RMS series is designed for Automation and Supervision (Current measurement for process regulation by distributed PLCs or remote control), Safety and Condition Monitoring (load monitoring for protection systems and predictive maintenance), Energy management (Convenient connection to power consumption sub-meters), Battery banks, Power supplies, Electric heating elements.


The new flexible Rogowski coil CT with the built-in Integrator.
The JRF MOI series with the built-in integrator of revenue grade current transformers has been released.

These exceptionally high-accuracy, 1.57” (40mm) to 4.13”(105mm) opening CTs have primary current 100A to 6000A AC and secondary output 333mV AC.
The JRF MOI series complying with IEC61869-2 provide accuracies of ±1.0% from 5% to 120%, 150%, 200% of rated current for loads up to 6000 amps.

The UL61010-1 recognized New JRF-MOI series for power meter.
They meet IEEE/ANSI C57.13 class 1.2 accuracy or class 0.6 accuracy.
The device greatly simplifies installations to meet the increasing demand for accurate current measurement on conductors where traditional split-core and solid-core CTs are difficult to use.

With its flexible design, the JRF MOI series is perfect for large bus bars and irregular-shaped conductor bundles.

The new JRF MOI series offers a small, flexible profile, enabling it to be used on conductors in tight spaces where rigid CTs won’t fit.

The revenue-grade accuracy of JRF MOI series flexible Rogowski coil CT provide enhanced performance in current and power monitors as well as energy meters.
