1. Product Description

PMAC615 digital panel meter is designed for single-phase measurements of AC power

signals and related parameters. Instead of traditional pointer meters, relay and other

components, PMAC615 digital panel meter integrates sampling and control function, which

is suitable for various low voltage single phase system.

PMAC615 digital panel meter provides an optional RS485 communication port to link with

PLC, PCs and SCADA system. Users can program the parameter via RS485 COM easily.

PMAC615 digital panel meter is made by complicate frequency locking technology which

supports up to 0.2% high accuracy measurements for non-liner load. Users may read the

measurement value from LED panel or via software.

Besides, PMAC615 provides optional two status inputs, one relay output for different

application. User can choose the DI/ DO flexibly. And its pluggable terminals connection is

easy for local wiring or maintain.
