LE-01d – Single-phase Electronic Energy Meter with Pulse Output

LE-01d is a static (electronic) single-phase energy meter designed for direct AC power measurement. It is MID-certified and features a clear LCD display and an LED that indicates real-time energy consumption.

Function and Measurement Principle

A special electronic circuit generates pulses in proportion to the energy consumed, based on the current and voltage passing through the meter. Consumption is indicated by a blinking LED. The pulses are converted into energy values displayed on the segment-based LCD. The digits after the decimal point represent hundredths (0.01 kWh = 10 Wh).

Pulse Output (SO+ / SO-)

The meter is equipped with a pulse output that allows connection to external pulse reading devices. Note that this connection is not required for the meter to operate correctly.

Sealability

The meter can be sealed at both input and output terminals to prevent unauthorized bypassing or tampering.

Individual Serial Number

Each LE-01d unit is marked with a unique laser-engraved serial number that cannot be removed, ensuring secure identification and traceability.

Features and Benefits

• ✅ Direct measurement up to 50 A
• ✅ LED indicator for kWh reading
• ✅ LCD display with two-decimal precision
• ✅ Pulse output (SO+ / SO-) for external monitoring
• ✅ Sealable to prevent manipulation
• ✅ Laser-engraved unique serial number

Applications

LE-01d is suitable for residential, industrial, and commercial installations where accurate and reliable energy measurement is essential.

Installation

1. Disconnect power supply.
2. Mount the meter on a DIN rail (TH-35) inside the distribution board.
3. Connect phase (L) to terminal 1 and neutral (N) to terminal 4.
4. Connect output phase to terminal 3 and output neutral to terminal 6.
5. RS-485 connection (optional): A+ to terminal 20, B- to terminal 21.
6. Seal the terminal covers if needed.
