  • PQ-CT - JPS series
    High accuracy split-core transformer certified UL Listed (UL61010-1) with Pollution Degree 3, CAT IV 600V.
    Optimized for Renewable energy power monitoring, Distribution circuit metering and Power quality metering....

  •  PQ-CT JPS series is a high accuracy split-core current transformer, certified UL61010-1 Listed, Pollution Degree 3 with CAT4 600V (Altitude 3000m). The JPS series offer the high accuracy and low phase shift, and the easy two-handed opening and closing, with a safe output values of 100, 250, 333, 500, 1000mVac of voltage output and 50, 80, 100mA, 1A, 5Aac of current output.

     The JPS series fulfill the standards, IEEE C57.13 Class 0.3 & 0.6 accuracy and IEC 61869 Class 0.2S & 0.5S accuracy. Designed specifically for Revenue grade energy and power quality meters, the JPS series is available in four window opening sizes of 10mm / 20mm / 33mm / 52mm, with the current measurements 5A to 1,500A. All models are available in standard and revenue-grade accuracies and offer a wide range of reading from 1% to 120% of primary rated current, wider than other standard current transformers.

     The JPS series revenue-grade split core CTs are optimized for Renewable energy power monitoring, Distribution circuit metering, and Power quality metering. They have a hinged opening mechanism for easy installation.

  • PQ-RoCoil - JRFS series
    Flexible Rogowski coil current transformer which can be installed around bus bars and multiple conductors.
    Intended for field installation within panelboards, switchboards and industrial control equipment....

  •  The JRFS series flexible Rogowski coil current transformer can monitor AC line current in circuits up to 1000 Vac and nominal currents up to 6000 Amps. They can be opened and are flexible for ease of installation around bus bars and multiple conductors. They are intended for field installation within distribution and control equipment such as panelboards, switchboards and industrial control equipment to measure the current on branch circuits and feeders.

     The JRFS series CTs may be used with electric energy meters, like the power meters, or for other current measuring purposes. PQ-RoCoil is different in a few key ways from standard CTs. They do not contain a ferromagnetic core, so they don’t saturate, they have excellent linearity, and they have very low phase angle errors. Because they lack a core, it is possible to make them flexible and lightweight. Furthermore, the coil output signal is low voltage (less than one volt AC) and low current (microamps or less), so they are safer than ratio CTs.

  • Power quality meter - JAGUAR 6300S
    High accuracy digital power quality meter with Class S (IEC61000-4-30 ed 3)...

  •  J&D new power quality meter, JAGUAR 6300S is a high accuracy digital power quality and energy meter. JAGUAR 6300S provides power quality information which enables management of energy use, power facility operation and high efficiency device analysis. It presents an energy management supervisor the analytic criterion on both energy use and power quality, which makes it possible to establish appropriate preventive or post measures.

     JAGUAR 6300S has two Ethernet ports which enables network connection just by direct STP/SFTP cabling between two meters without hubs. By RS485 communication, JAGUAR 6300S can be connected to other meters for multiple connection.

     JAGUAR 6300S provides 0.2% of accurate measurement for voltage and current. Active power/energy conforms to IEC61557-12 Class 0.2S, and Reactive power/energy does to IEC61557-12 Class 0.5S. It can measure various parameters for power quality such as Sag/Swell, Crest Factor, K factor and harmonics (up to 63rd).
