OB4373 CT DIN Rail Three Phase Digital Meter with Calibrated Rogowski Coils

OB4373 CT Operated three phase high-precision kWh meter complete with a set of calibrated Rogowski coils, 5m cable and a 5V DIN rail power supply.

Features: Firmware upgradable, max/min/average demand, programmable digital output for loadshedding, export limitation, reverse relay, transformer metering, compatible with LV,MV, HV applications, harmonic analysis, phase sequence indication, allows CT/PT configuration, 5v DC output for communication equipment, dual source inputs for utility/generator measurement Class 1 accuracy with RS485 MODBUS RTU: baud rate, modbus ID, parity, Bi-directional, import/export, instant volt, amp, power factor, frequency, active power, reactive power, apparent power, programmable load survey/profile intervals, voltage asymmetry, true RMS measurements. Over 300+ parameters measured.

Our Rogowski coil range can be used in similar circumstances to current transformers - in many instances they have added advantages including:

• Wide dynamic range
• High lineraity
• Very useful with large size cables or awkward shaped conductors or in places with limited access
• No danger from open-circuited secondaries
• No damage by large overloads
• Non-instrisive - do not draw power from the main circuit carrying the current to be measured
• Light weight
