A digital power meter that adopts a multi-channel method and allows parameter measurement from single-phase two-wire to three-phase four-wire connection methods.
The 66203/66204 is a digital power meter designed for measuring single-phase/three-phase output, suitable for a wide range of electrical products. (66203: 3-channel type, 66204: 4-channel type). The 66203/66204 supports various wiring methods (single-phase 2-wire/single-phase 3-wire/three-phase 3-wire/three-phase 4-wire) and can measure voltage, current, power, and other parameters for each wiring method. By adopting a wide voltage and current range, the 66203/66204 enables high-precision measurements. Unlike conventional analog models, it employs 16-bit high-resolution analog-to-digital conversion and high-speed digital signal processing (DSP) technology that supports frequency measurements up to 250 kHz. The 66203/66204 complies with ENERGY STAR/IEC 62301/ErP standards. The product features two types of shunts internally, allowing for low power measurements under 30 mW in no-load mode with a minimum current range of 5 mA. Additionally, for current measurements above 20 Arms, external shunts and current transformers (optional) are available.
