The CW240 supports up to four single-phase two-wire systems, two single-phase three-wire systems, 3P4W plus neutral, and even SCOTT connections. The CW240 supports currents ranging from 200.0 mA to 3000 A and voltages up to 1000 V. Electric power (instantaneous values, electric energy, and demand), harmonics, voltage fluctuations (dip, swell, and instantaneous power failure) and waveform can all be measured simultaneously up to 512MB flash memory.

Input System: Single-phase 2-wire to 3-phase 3-wire (CW120), 3-phase 4-wire (CW121)
Measurement Functions: Voltage, Current, Frequency, Active power, Reactive power, Power factor, Active electric energy, Regenerative electric energy
Features: Large capacity of memory (ATA flash memory card), Wiring error check function, 2 or 3-load system, capability and AP140-E application software.

Panel-mounted power and energy meter with a large, three-row LED display integrates all the measuring functions required for power management in substations, factories, process plants and office buildings. PR300 users are interested in allocation of energy costs, conservation of energy and overall electrical system reliability. Other benefits of using the PR300 are reduction of panel space and wiring due to multifunctional capability, and access to LAN for centralized monitoring of power useage and demand.

CW Viewer AP240E is data analyzing software for the CW240 and CW120/121 Clamp-on Power meter. Making full use of the rich measuring functions of the CW series units, which efficiently manages the large amounts of measurement data.
OS: Windows 2000 Professional / XP HomeEdition / Professional Edition

CTW Series are clamp-on type Current Transformers that can be mounted without cutting cables when upgrading existing equipment. Standard lineup includes 100A, 200A, 500A and 800A models. Also compact and light-weight 100A and 300A models are available. CTW Series contain a built-in device for suppressing hazardous voltages that prevents a burnout or outage at the open-circuit of secondary line.

CTU Series are separate, wall-mounting type Current Transformers that can be mounted without cutting cables when upgrading existing equipment. Standard lineup includes 100A, 200A and 500A models.
