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.
