Introduction

Front of power panel with panel meters

Power Panel with Installed Meters

Panel meters are installed on the front cover of the power panels for convenient reading. They measure the voltage, current, power, energy, power factors and other electrical parameters that are useful for energy tracking and management.

Multi-function panel meter

Multi-function Panel Meter

This meter replaces more traditional single and three meters that are built for a single purpose and measure only one electrical parameter by combining all the measured parameters into one unit.

Digital Communication

Equipped with an RS485 communication interface allows these meters to be connected to various third party SCADA software for monitoring and control purposes.

Features

Special Purpose Metering IC

Made with an IC designed specifically designed for metering, even very low currents can be measured accurately.

Small footprint and low depth

With its small footprint and low depth, they are ideal for installation in subpanels.

Dedicated CTs

Can be used with regular CTs, but even better with highly accurate and space saving dedicated CTs.

Accuracy Class

This series of meters are highly accurate with a class of 0.5. To maximize this accuracy, we recommend using them with our dedicated CTs which can have an accuracy as good as 0.2% for the solid core series.

CT Selection

CTs installed within existing panels

All panel meters require external CTs, but regular CTs are large and occupies a lot of space, often they are too big and bulky to fit within an existing panel and necessitating the addition of a new panel just for the CT, and at times even demanding the cumbersome process of having to rewire even the existing power panel. Our dedicated CTs are small enough to fit into existing panels, obviating the need for all this trouble.

Zero Reset

Some applications require that the meter be reset back to zero, our meters allow the user two ways of doing so.

Reliability

FCC and CE certification, as well as passing independent lab testing are the best indicator of our meter reliability.

Note that meters are on the front lines of any power installation. When there is a power surge, it is often the contactor and meter that bear the brunt of that surge, as such meters need to pass a 6kV surge test.

Communications

A remote host needs only to issue one command to read all the important parameters, greatly improving the host software update cycle.

Once the meter receives a command, it can respond by sending the requested data within 20 milliseconds.

  1. For the kWh measurement of three phase power, which can then be read by a remote host through its communication link.
  2. Communicates using the standard Modbus/RTU over an RS485 interface.
  3. For use with regular 5A output CTs.
  4. Can be configured using the on-board keys, no need for any special tool or software.

PM200

PM200 kWh panel meter

The PM200 is panel meter that measures both the real power and energy of a three phase system.

Unlike analog to digital based meter, the PM200 uses the latest digital IC specially designed for metering use. This allows the PM200 achieve high accuracy for a wide range and even for very low current values.

The PM200 has Modbus over RS485 communication allows a remote host to perform not just auto meter reading but to do so in near real time.

The PM200 is not limited to using regular 5A output CTs, but are also available with models that can be used with our dedicated CTs.

PM250

PM200 kWh panel meter

The PM250 is a multi-function panel meter with the ability to measure various electrical parameters including V, A, kW, kVAR, PF, kWh, kVARh, Hz and others.

The PM200 has Modbus over RS485 communication allows a remote host to perform not just auto meter reading but to do so in near real time.

Special purpose models available:

  1. Models to be used with our dedicated CTs.
  2. PM250-4 demand response model.
  3. PM250-X dual source model.
  4. PM250-P pulse output model.
