Application:

The energy meter is designed to measure active (real) power in single phase distribution systems. It conforms to the requirements of the standard EN61036+A1, IEC62052-1 and IEC62053-21.

Modules of the meter:

• Measuring module
• Register
• Terminal block with a cover and a seal
• Case with a cover and a seal

Technical features:

• Easy to use software with a strong program protection against unauthorised access
• 4 tariffs + a tariff for the reversed power
• Communication with a Hand Held Terminal via Optical interface;
• Communication with a PC or Power Line modem via Current Loop interface
• A built-in clock with the following functions:
- Indication on the LCD of the real time, day, month and year (calendar). It supports also a leap year correction
- In case of a power supply absence the Li battery supports the operation of the clock for a period of 10 years.
- Supports daylight saving time change
• A calibration output with a frequency proportional to the consumed power in accordance with the energy meter constant
• Supports bi-directional energy measurement
• Resistance against electromagnetic HF fields, electrostatic discharge and radio interference
• The case, the terminal block and the covers (EN 61036+A1)
- Made of thermoreactive materials, isolated from dust
- The terminal block and the main cover are protected against unauthorised opening with two seals
