Split-Core(Clamp-on)CT
iSAST OPEN CT
1) Low VA CT (JC / JS / JSC) on primary current digital power
Low VA Split core Current transformer for primary current (1A / 5A output), JSC / JS / JC series applied with precise core split cutting technology. It is designed for strong durability and improves both existed error in low current and error occurred by ‘external vibration and shock’ to minimize tolerance on cutting cross section of core. Rated current is 60A-2400A, it satisfies with IEC60044-1 0.5 / 1.0 / 3.0 grade and ANSI 57.13 0.6 / 1.2 grade. It certifies with security accreditation IEC61010-1, UL61010-1 and EN61010-1 as official document.
2) mA CT
A mA output Split core Current transformer for precise power and energy measuring, JSC / JS / JC series are applied with precise core split cutting technology. It is designed for strong durability and improves both existed error in low current and error occurred by ‘external vibration and shock’ to minimize tolerance on cutting cross section of core. As compact one-touch split structure and built in over-voltage-protection-circuit, it offers best solution to connect on primary current directly for security and fast installation on digital power meter instead of cutting power line. Rated current is 5A-2400A, it satisfies with IEC60044-1 0.5 / 1.0 / 3.0 grade and ANSI 57.13 0.6 / 1.2 grade. It certifies with security accreditation IEC61010-1, UL61010-1 and EN61010-1 as official document.
3) Transducer
Split core Current transducer, RMS/V/VH Series, is designed for energy management, with a convenient connection to electronic submeter. It may also be applied for current measurement in a system of distributed power line carriers (PLCs) or remote controls such as SCADA software for automation and supervision. Other applications include security and condition monitoring, load monitoring, in protection systems, and for predictive maintenance of conveyers, pumps or HVAC motors.
Clamp-onflexible Rogowski coil CT
iSAST OPEN RCT
JRF Series which applies with high accuracy coil winding technology on air core that show precise quality from low current to high current and provide optimizing solution to improve conductor positing error and influence of external magnetic field in energy meter and protection measuring technology industry. As split clip flexible outfit, it is simply installed even at limitary space instead of cutting power line.
As major features per series, JRF55 / 80 / 105 are designed for compact split clip type and it shielded on joint clip part to maintain less than 1% error by conductor position. JRF 1 / 2 / 3 are designed as clamp type for easy mobile installation and tighten up durability. JRF 1S / 2S / 3S are designed with optimized shielding technology to block influence of external magnetic field completely from high current. Transducer type as Rogowski and integrator joint device are applied with advanced and optimized integration technology and show high accurate characteristic.
Rated current is 250A-6000A and it satisfies with IEC60044-8 0.5 / 1.0 grade and it certifies with security accreditation IEC61010-1, UL61010-1 and EN61010-1 as official document.
AC/DC Current Probe
iSAST OPEN CP
Clamp current Probe offers portable current measuring with 5 to 1,000A input to mA / 1A / 5A AC output and mA / 0-5V DC output. It improves both existed error in low current and error occurred by external vibration and shock as strong durability and minimized tolerance on cutting cross section of core. Main application is power analyzer, portable power meter tester and portable smart meter tester, etc.
