LE-03MP
Electric energy meter,
3-phase
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.
Purpose
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.
Functioning
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.

Summary of Contents for F&F LE-03MP

  • Page 1 Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health. Purpose 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.
  • Page 2 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.
