The JAGUAR 6300S is a high quality power quality and energy meter developed by J&D Electronics. JAGUAR 6300S makes it possible for enterprises to monitor electric power energy and to control power distribution system.

J&D AC/DC CTs provide non-contact detection of AC/DC current. The AC/DC CTs have two types of split-core & solid-core design with various utility, high reliability & cost-effective solution for precise current measurements.

WI-GEM & MULTI-GEM NETWORK SYSTEM consists of WI-GEM(EMU, EMR, EMC) with ZigBee solution & 18Ch. MULTI-GEM. WI-GEM & MULTI-GEM NETWORK SYSTEM is used for monitoring of energy or electrical parameters at distribution panel of IDC, Building, Shopping Mall, Factory.

Miniature Split-core AC Current Transformer is suitable for primary ranges from 5A to 2,400A AC with mA, 0.1A, 1A, 5A, 333mV AC secondary. It improves both intrinsic errors in low current and errors occurred by external vibration and shock with strong durability and mimum tolerance on cutting cross section of core. Main applications are sub metering, power meter, PLC (Programmable
Logic Controller), energy automation and etc.

Miniature Split-core AC Current Transformer is suitable for primary ranges from 5A to 2,400A AC with 4-20mA, 0-5V, 0-10V DC
secondary.
It improves both intrinsic errors in low current and errors occurred by external vibration and shock with strong durability and
minimum tolerance on cutting cross section of core. Main applications are sub metering, power meter, PLC (Programmable
Logic Controller), energy automation and etc.

Applying laminated split core technology and open loop technology split core DC current transducer is designed for strong durability. It improves not only existing errors at the low current but also errors occurred by ‘external vibration and shock’ to minimize tolerance on cutting cross section of core. As a simple one touch split structure, it offers best solution for security and
fast installation on high frequency monitoring device without cutting power line. Rated current is DC 5A-2,000A. Main applications
are inverter monitoring, DC smart meter, PV energy saving and etc.

iSAST OPEN RCT is made with high accurate coil winding technology on air core which shows precise quality from low current to high current and provides optimizing solution. It improves both conductor positioning error and influence by external magnetic field. As split clip flexible outfit, it can be easily installed even at limited space without cutting power lines. Main applications are power distribution monitoring, high current measuring, sub metering and etc.

J&D Rogowski coil current transducer is suitable for primary ranges from 250 to 6,000A AC with 4-20mA and 0-5V DC secondary. It improves both conductor positioning error and influence by external magnetic field. As split clip flexible outfit, it can be easily installed even at limited space without cutting power line. Main applications are Protection systems monitoring, Condition monitoring, Process / Control monitoring for PLCs and SCADA software, and etc.

iSAST CT, JDCT series are made of combined core with DC immunity and minimized infuence from external magnetic eld for Anti-external magnetic meter. It is recommended to use with shielding plates inside of meter case. They are complying with IEC 62053-21 or ANSI C12.20 of meter standard.

It improves both existing errors in low current and error occurred by external vibration and shock with strong durability and minimum tolerance on cutting cross section of core. Main applications are power analyzer, portable power meter tester and portable smart meter tester, etc
