Introduction

The SDM530C is a three phase multi-function remote control energy meter. It measures all

important electrical parameters, such as Active Energy (kWh), Current (A), Voltage (V),

Frequency(Hz), Power Factor, Power Demand, import and export energy etc. With built-in relay

inside, the meter can be remotely controlled to turn on or off the electricity supply via RS485.

The user can also set alarm objects and alarm level, once the alarm is activated the relay will be

turned off.

Unit Characteristics

The Unit can measure and display:

Line voltage

Frequency

Line Currents

Power, maximum power demand and power factor

Active energy imported and exported

Reactive energy imported and exported

The unit has password-protected set-up screens for:

Changing password

Demand Interval Time(DIT)

Pulse Output Duration

Backlit Lasting Time

Display Scroll Time

Modbus Setting

Example shows the Pulse Duration is 100ms.

Please note: When the Pulse Constant is

1000imp/kWh, the pulse duration is fixed with

35ms.

This option allows user to configure the pulse

output. The output ca be set to provide a pulse

for a defined amount of active or reactive

energy. Use this section to set up the relay pulse

output-Units: kWh, kVArh.

Default: P kWh ( active energy)

Example shows Pulse Output type: kWh ( active )

Example shows Pulse Output type: kVArh

(reactive)

This sets the period in minutes over which the

current and power reading are integrated for

maximum demand measuremen

t. The options

are 0~60.

Example shows the DIT is 60 minutes.

This sets the Display scroll time.

Options:0~30s

Example shows the display will scroll every 30s.

Please note: 0 means the display scroll is closed.

No display scroll

This meter provides a function to set the blue

backlight lasting time (off on, 5, 10, 20, 30, 60,

120mins )

Example shows the backlight will be off in

60mins.

Please note: Off means backlight always off; On

means the backlight always on here.
