Novatek-Electro RN-118 Single-Phase Voltage Monitoring Relay 230V 5-900s

The Novatek-Electro RN-118 is a high-precision single-phase voltage monitoring relay engineered for 230V electrical systems. This device serves as a critical protective component, continuously monitoring the supply voltage to ensure it remains within safe operating limits. By detecting deviations such as overvoltage or undervoltage, the relay automatically disconnects the load to prevent damage to sensitive electronics and industrial machinery, reconnecting only when the power supply stabilizes.

Advantages

The primary benefit of the RN-118 is its robust protection against power quality issues that can lead to equipment failure or shortened lifespans. Its adjustable time delay feature, ranging from 5 to 900 seconds, offers significant flexibility, allowing users to tailor the reconnection timing to the specific requirements of their connected appliances, such as refrigerators or compressors that require a stabilization period. The compact design ensures easy integration into standard electrical distribution panels, while the high-quality internal components guarantee long-term reliability and consistent performance in various environmental conditions.

Suitable for

• Residential electrical systems to protect household appliances
• Industrial control panels for monitoring sensitive machinery
• Office environments to safeguard computers and servers
• HVAC systems requiring stable voltage for compressors

This device may not be suitable for three-phase electrical systems, as it is specifically designed for single-phase 230V applications. Additionally, it should not be used in environments where the load current exceeds the relay's rated switching capacity without the use of an external contactor.

Key specifications

• Rated voltage: 230V AC
• Adjustable time delay: 5 to 900 seconds
• Monitoring type: Single-phase voltage
• Application: Protection against voltage fluctuations

To use the RN-118, install the device on a standard DIN rail within your distribution board. Connect the input power supply to the designated terminals and wire the load through the relay's output contacts. Once installed, use the adjustment dial to set the desired time delay based on the specific needs of your equipment. Ensure all connections are tightened securely and verified by a qualified electrician before energizing the circuit.

What to consider before purchase

• Verify that your electrical system is single-phase 230V
• Check the total power consumption of your load to ensure it is within the relay's limits
• Ensure there is sufficient space on the DIN rail for installation

Usage recommendations

For optimal protection, it is recommended to periodically inspect the relay connections and verify that the time delay settings remain appropriate for the connected equipment, especially after any changes to the electrical load.
