Single Phase Power Controller and Monitoring Relay OM-163
– Threshold Comparison: The user sets maximum permissible thresholds for the controlled parameters:
* Max/Min Voltage (U_{max}, U_{min}): The acceptable voltage range.
* Max Power (P_{max}): The limit for total, active, or reactive power.
* Max Current (I_{max}): The current overload limit.
* Internal Temperature: It also monitors its own contact group temperature (85 deg Centigrade limit).
* Max/Min Voltage (U_{max}, U_{min}): The acceptable voltage range.
* Max Power (P_{max}): The limit for total, active, or reactive power.
* Max Current (I_{max}): The current overload limit.
* Internal Temperature: It also monitors its own contact group temperature (85 deg Centigrade limit).
– Protection Mechanism (Disconnection):
* If any of the monitored parameters (Voltage, Current, Power) exceeds the set maximum limit, or if the voltage drops below the minimum limit, the internal microcontroller triggers the relay to open its output contacts, thus disconnecting the connected load and protecting the equipment.
* A user-set off-delay time allows for minor, short-term fluctuations without unnecessary tripping.
* If any of the monitored parameters (Voltage, Current, Power) exceeds the set maximum limit, or if the voltage drops below the minimum limit, the internal microcontroller triggers the relay to open its output contacts, thus disconnecting the connected load and protecting the equipment.
* A user-set off-delay time allows for minor, short-term fluctuations without unnecessary tripping.
– Display and Indication: The OM-163 features a digital 3×7 segment LED display to show the current real-time values of voltage, current, and the different power types, along with LED indicators for the relay’s status (ON/OFF).
– Automatic Reclosing (AR): After a disconnection due to a fault, the device waits for a user-set Automatic Reclosing (AR) delay time.
Key Advantages of the OM-163 –
The OM-163 is a versatile device that offers multiple protection and monitoring functions in a single unit, providing several advantages:
– Multi-functional Protection (All-in-One): It combines the functionality of several different devices into one unit, acting as:
* Power Consumption Limiting Relay: Prevents exceeding a set maximum power limit, which is useful for utility contracts or capacity management.
* Voltage Relay: Protects equipment from damaging over-voltage and under-voltage conditions.
* Overcurrent Relay: Acts as protection against high load current or overload.
* Thermal Protection: Disconnects the load if its internal contact group overheats (>85 deg Celcius), enhancing safety and device longevity.

Novatek Electro India’s OM-163 is a multifunctional, single-phase power monitoring relay designed to protect electrical equipment by disconnecting the load when power consumption or mains voltage & current deviates from user-set limits.
How the OM-163 Works –
The OM-163 works based on continuous measurement, comparison, and control of electrical parameters using a microcontroller.
– Continuous Monitoring and Measurement: The device is installed in the electrical panel or distribution box typically on a DIN-rail, and continuously monitors the single-phase supply voltage, load current, and calculates power consumption (total, active, and reactive power).
