1.Introduction

This document provides operating, maintenance and

installation instructions. This unit measures and displays

the characteristics of single phase two wires(1p2w),three

phase three wires(3p3w) and three phase four wires(3p4w)

networks.The measuring parameters include voltage(V),

frequency(Hz),current(A),power(kW/Kva/Kvar), mport, i

export and total Energy(kWh/kvArh).The unit can also

measures Maximum demand current and power. his is T

measured over preset periods of up to 60 minutes.

This unit is a 1A or 5A current transformer operated and can

be conﬁgured to work with a wide range of CTs. Built-in pulse

and Modbus or M Bus outputs.Conﬁguration is password -

protected.

This unit can be powered from a separate auxiliary (AC or DC)

supply. Alternatively it can be powered from the monitored

supply by linking the voltage reference and neutral reference in

to terminals 5 and 6 (Please refer to wiring diagram).

1.1 Unit Characteristics

The unit can measure and display:

• Voltage and THD% (total harmonic distortion) of all phases

• Line frequency

• Currents,current demand and current THD% of all phases

• Power, maximum power demand and power factor

• Active energy import d and exportede

• Reactive energy imported and exported

1.2 Current Transformer Primary Current

voltage PT secondary

voltage value. The default

value is 230V.

Secondary PT setting

Press to enter the

PT secondary voltage

selection routine. The

range is from 100 to 500V.

For example, if set the ratio to be 100,it means the primary

voltage equals secondary voltage x100.

Set CT Ratio value

Press to enter the

CT Ratio setting screen.

The range is from 0001

to 2000.

For example, if using a 100/5A current transformer you

will enter 0020, as you need to divide the primary by the

secondary to get the ratio (CT rate).

Set PT ratios value

Press to enter the PT

ratio screen.

The range is from 0001

to 9999.

As an example: If using 100/5A CT, you will need to insure

CT2 (Secondary) is set to 5 and CT rate is 0020. You divide

the primary by the secondary to get the CT rate to be entered

(100/5=20).
