Ce-dj42 3 Phase Voltmeter Ammeter With Rs485

The Ce-dj42 is a three-phase AC intelligent digital meter that measures voltage, current, power, and power factor with an accuracy class of 0.5 or 0.2 for current and voltage inputs. It features RS485 communication at 9600bps with 8N1 data format, relay switch output rated at 5A/250VAC, and analog outputs of 0-5V or 4-20mA configurable per user setting. The unit displays values up to 9999 with voltage resolution of 0.1V and current resolution of 0.001A, making it suitable for precise monitoring in industrial control panels.

The device operates on an auxiliary power range of 85 to 265V AC and consumes no more than 4.5VA. It includes galvanic isolation between power, input, and output circuits rated at 2.5kV DC for one minute, with surge immunity up to 4kV. The housing is made from standard engineering plastic, and the faceplate is designed for panel mounting with a 91x91mm cutout. These specifications align with typical industrial-grade metering instruments used in automation systems where electromagnetic compatibility and signal integrity are critical.

This instrument is commonly purchased by electrical contractors, automation integrators, and facility managers who require real-time monitoring of three-phase power parameters without external sensors. Buyers typically use it in control rooms, motor control centers, and energy management systems. Trade terms are standard for industrial instruments: FOB Chongqing port, lead time around 15-20 days after order confirmation, and packaging in cardboard boxes with foam inserts. Minimum order quantities are not specified but are typically negotiable for bulk orders.
