LE-03MP

Electric energy meter,

3-phase

The LE-03MP is a static (electronic) calibrated electricity meter

of three-phase alternating current in a direct system. It is used

for reading and recording of consumed electric energy and ma-

ins parameters with remote readout via a wired RS-485 network.

Under the influence of flowing current and applied voltage, the

LE meter accurately measures the amount of consumed electrici-

ty. Energy consumption is indicated by flashing LEDs: 800 pulses/

kWh for active power and 800 pulses/kvar for reactive power. In

addition, the device measures the mains parameters. The values

are displayed cyclically on LCD display. Parameter changes every

3 seconds. You can manually switch between successive parame-

ters by pressing a button on the front-end of the meter.

The display is active only with meter power supply on.

Do not dispose of this device in the trash along with other waste!

According to the Law on Waste, electro coming from households free of charge and can

give any amount to up to that end point of collec� on, as well as to store the occasion of

the purchase of new equipment (in accordance with the principle of old-for-new, regard-

less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the

environment and human health.

The meter has an internal relay that switches L1, L2 and L3 cir-

cuits. The (ON/OFF) relay can be also operated manually.

The meter has a program overcurrent protection. If the load

threshold is exceeded, the internal relay opens for 5 minutes.

After that time the relay closes and the measurement is repe-

ated.

Prepaid power (prepayment feature) is the set increment value

of available active power beyond which the internal relay is di-

sconnected by the meter.

Automatic operation is the mode with two active functions: au-

tomatic relay disconnection if the set overcurrent threshold is

exceeded and switching on the prepaid mode.

Current state of relay (ON/OFF) is indicated on the LCD display as

the corresponding Modbus register value.

Readout of all measured values and parameter setting functions

is done via the Modbus RTU protocol.

Communication with the meter working as a Slave is performed

in accordance with Modbus RTU standard via RS-485 serial port.

Converted registers values give results consistent with the indi-

cations on the meter display.

Each indicator is identified by a unique address assigned by the

user.

IrDA (infrared data transmission ) feature is inactive in the

current version of the software.

»Internal relay switching L1, L2, L3 phase circuits.

»Remote control of ON/OFF relay.

»Overcurrent protection – setting the load threshold.

»Prepaid power (prepayment) – active power value at which

the meter disconnects the internal relay.

»Automatic mode – activation of overcurrent protection and

prepaid mode.

»Status – current status of the relay [ON/OFF].

The indicator has a pulse output. This allows you to connect a

pulse meter-reading pulses generated by the counter. For proper

operation of the indicator is not required to connect additional

devices.

Change of meter address is done via the RS-485 port using the

Modbus RTU protocol command to set the desired value in the

meter register. The default meter address: 1.

The meter is marked with individual serial number allowing its

unambiguous identification. The marking is laser engraved and

cannot be removed).
