User Manual
IntroductionApplications
Features
The unit measures and displays the characteristics of single phase two wires (1p2w), three phase
three wires (3p3w,) and three phase four wires (3p4w) supplies, including voltage, frequency,
current, power ,active and reactive energy, imported or exported. Energy is measured in terms
of kWh, kvarh. Maximum demand current can be measured over preset periods of up to 60min-
utes. In order to measure energy, the unit requires voltage and current inputs in addition to the
supply required to power the product. The requisite current input(s) are obtained via current
transformers (CT). This meter can be congured to work with a wide range of CTs, giving the unit
a wide range of applications. Built-in interfaces provides pulse and RS485 Modbus RTU outputs.
Conguration 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, where appropriate.

Current Transformer Primary Current
RS485 Serial Modbus RTU Pulse output
Strider M4 V2 Series is CT operated. you will need to set the correct ratio.
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).
This uses an RS485 serial port with Modbus RTU protocol to provide a
means of remotely monitoring and controlling the Unit.
Set up screens are provided for setting up the RS485 port.
This provides two pulse outputs that cloc k up measured active
and reactive energy. The constant for active energy is 3200imp/k
W h (Terminals 11& 12). The pulse width for pulse 1(Terminals 9&10)
can be set from the s et up menu.

CT Settings
The CT option sets the secondary current (CT2 1A or 5A) of the current transformer (CT) that wires to the meter.
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).
* Please note for the MID approved version device,you will only have one opportunity to set the ratio.
From the Set Set-up menu, use and
buttons to select the CT option.

PT Settings
The PT option sets the secondary voltage (PT2 100 to 500V) of the Voltage transformer (PT) that wires to the meter.
