APATOR OTUS 3 for RES Three Phase Electricity Meter
Product Information
The OTUS 3 is a bidirectional smart meter designed for photovoltaic installations that operate in the power grid. It is specifically designed to facilitate the settlement of prosumers using the net energy metering method (NEM) and allows for any method of energy balancing. The meter is suitable for use in both autonomous or stand-alone installations.
Key Features:
- Bidirectional measurement of active energy
- Four-quadrant measurement of reactive energy
- Four tariff metering
- Measurement of voltage, current, instantaneous power, and maximum power
- Recording measured data in various profiles: 15-minute load profile, 10-minute voltage and phase current profile, daily profile, and monthly billing periods
- Integrated disconnector
- Local communication via infrared port (EN-62056-21), DLMS/COSEM protocol
- Remote access via interchangeable GSM-based communication module located under the terminal cover, RS485 port (optional)
The OTUS 3 is named after an owl, symbolizing wisdom and intelligence in Latin.

Product Usage Instructions
To use the OTUS 3 meter:
- Make sure the meter is properly connected in accordance with the specified connection method.
- Ensure the rated voltage is appropriate for your installation.
- Set the reference current (Iref) and maximum current (Imax) based on your requirements.
- Take note of the frequency at which the meter operates.
- Refer to the user manual for instructions on how to configure the meter for bidirectional measurement of active and reactive energy.
- If required, set up the four tariff metering feature.
- Monitor voltage, current, instantaneous power, and maximum power using the meter’s display.
- Record and analyze measured data in the various profiles available: 15-minute load profile, 10-minute voltage and phase current profile, daily profile, and monthly billing periods.
- If necessary, utilize the integrated disconnector for local disconnection.
- For local communication, use the infrared port with the EN-62056-21 protocol or the DLMS/COSEM protocol.
- For remote access, install the interchangeable GSM-based communication module located under the terminal cover or utilize the RS485 port (optional).
- Ensure the meter’s operating temperature is within the specified range.
- Take note of the casing’s ingress protection rating to ensure suitable protection against external elements.
- Refer to the standards specified in the user manual for compliance and safety considerations.
