Voltage relay with limiter function, LCD, measurement up to 10kW, DIN rail mounting, OM-633

Intelligent energy management with power limiter OM-633

The OM-633 power limiter is an advanced device designed to automatically disconnect the power supply in case of exceeding the set power consumption value. Additionally, it monitors the voltage in the installation, protecting connected devices from its fluctuations. DIN rail mounted, it is an ideal solution for both professionals and home users who care about safety and optimizing energy consumption. Equipped with a clear LCD display, it allows for precise setting of operating parameters.

Functions and possibilities

OM-633 offers a wide range of adjustments and protections:

• Adjustable power threshold: Setting the power limit in the range of 1-10 kW allows you to adapt the device to individual needs and the characteristics of the installation.
• Voltage protection: Monitoring the supply voltage in the UL (150-210 V) and UH (230-260 V) range protects connected devices from damage caused by too low or too high voltage.
• Relay operation counter: Monitors the number of power disconnections, and after reaching the set value – automatically disconnects the power supply permanently (with the possibility of manual reset).
• Automatic blocking: In case of exceeding the set power threshold 5 times, the device locks the power supply for 10 minutes.
• Automatic shutdown: In case of power consumption 8 times higher than the set threshold or exceeding 16 kW, an immediate power disconnection occurs.
• Adjustable reaction time: The ability to set the device's reaction time (1 s - 3 min.) allows you to adapt it to the specifics of the load.
• Adjustable return time: Setting the power-on time (4 s - 6 min.) ensures stable system operation.

Application and benefits

The OM-633 limiter is used in:

• Homes and apartments: Protection of the electrical installation against overload caused by the simultaneous switching on of many receivers.
• Workshops and garages: Protection against damage to electrical equipment when starting engines or other high-power devices.
• Small businesses and retail outlets: Control of energy consumption and protection against unauthorized load on the installation.
• Smart home systems: Integration with building automation systems to optimize energy consumption and increase safety.

Thanks to the use of OM-633, you can:

• Increase the safety of the electrical installation.
• Prevent damage to electrical equipment.
• Optimize energy consumption.
• Avoid costly failures and downtime.

The limiter offers a power adjustment range from 1 to 10 kW, voltage protection in the range of UL 150-210 V and UH 230-260 V, as well as a rated current of 16 A. Mounting is done on a DIN rail.

It should be remembered that the limiter should not be used in circuits with electronic ignition (energy-saving fluorescent lamps), impulse power supplies and other devices generating harmonics of the third order and higher. The device is designed to operate at temperatures from -25°C to +50°C and has a protection class of IP20.
