PM1000 Series Power Meters PLSED309039EN

Chapter 1 – PM1000 Series Power Meters Product Description 08/2010

PM1000 Series Power Meters Technical Specification

The PM1000 series is a high-accuracy, low cost, ultra-compact, power, and

energy meter series. It offers ISO 9001 quality, accuracy and functional

flexibility. Selective models of this series have Modbus RTU

communications capability. The standard unit flush-mounts in a DIN 96

cutout and conforms to UL product standards.

The power meters are designed for retrofit applications such as replacement

of analog meters. Each can be used as standalone meter in electrical

control panels, power distribution unit (PDU), switch boards, uninterrupted

power supply (UPS), generator sets, and motor control center (MCC)

systems. It also provides easy communication to program logic control

(PLC), distributed control system (DCS), building management system

(BMS), and other systems.

The following table gives the technical specifications of the power meters.

Refer to ―Technical data‖ on page 71 for more information.
