Novatek-Electro RN-119 Single-Phase Voltage Monitoring Relay 230V 5-900s

The Novatek-Electro RN-119 is a precision-engineered single-phase voltage monitoring relay designed to protect electrical equipment in 230V systems. By continuously monitoring the supply voltage, this device ensures that connected appliances and industrial machinery remain safe from the damaging effects of power fluctuations, such as overvoltage or undervoltage conditions. With its adjustable time delay feature, it provides a flexible solution for maintaining system stability and preventing unnecessary shutdowns during minor, transient power disturbances.

Advantages

The primary benefit of the RN-119 is its robust protection capability, which significantly extends the lifespan of sensitive electronics by ensuring they operate only within safe voltage parameters. The device offers high reliability and ease of integration into existing electrical panels. Its adjustable time delay, ranging from 5 to 900 seconds, allows users to customize the response time based on specific equipment requirements, ensuring that the relay does not trip during brief, harmless voltage dips while still reacting quickly to sustained power issues.

Suitable for

• Residential electrical systems to protect household appliances
• Industrial control panels for sensitive machinery
• Office equipment protection against power grid instability
• HVAC systems and refrigeration units

This relay may not be suitable for high-voltage industrial applications exceeding the specified 230V rating or for three-phase electrical systems. It is also not intended for use in environments with extreme humidity or temperatures outside the manufacturer's specified operating range, as these conditions could compromise the internal electronic components.

Key specifications

• Nominal voltage: 230V AC
• Adjustable time delay: 5 to 900 seconds
• Phase type: Single-phase
• Mounting type: Standard DIN-rail

To use the Novatek-Electro RN-119, it must be installed by a qualified electrician onto a standard DIN-rail within an electrical distribution board. The input power lines are connected to the designated terminals, and the load is wired through the relay's output contacts. Once installed, the time delay can be adjusted using the integrated controls to match the specific restart requirements of the connected equipment. The device will then automatically monitor the line voltage and disconnect the load if the voltage levels fall outside the pre-set safety thresholds.

What to consider before purchase

• Verify that your system voltage matches the 230V specification
• Ensure there is sufficient space on the DIN-rail for installation
• Confirm the current rating of your equipment is compatible with the relay output
• Check local electrical regulations regarding the installation of monitoring devices

Always ensure the power supply is completely disconnected before attempting to install or adjust the relay to prevent electrical shock. Regularly inspect the device for any signs of physical damage or loose connections to maintain optimal protection levels.
