• over-voltage and under-voltage surges and fluctuations. When mains surges occur,
• it immediately cuts the supply to prevent damage and automatically restores power when the
• voltage parameters return to normal within a user-preset time.
• It will not allow mains surges to cause damage and so increases the lifetime of your equipment.
• The Over/Under Voltage Relay is a necessary device for a multitude of applications. Air conditioners,
• commercial and home applied refrigeration, freezers, security, computers, any industrial singe phase power load, office and home use appliances all need RN-111 protection to avoid damage and increase their life.

• trip settings (Umax, Umin, Reset delay) are adjusted in a wide range;
• fixed trip delay when voltage is 30V below/above user-set Umin/Umax threshold is provided;
• high accuracy for trip thresholds;
• fixed trip delay is provided to ignore starting voltage drops that cause nuisance tripping of the relay when Umin is reached;
• quite a high power of output contacts is provided that enables to extend the relay application range and in some instances to abandon auxiliary switching devices;
• two-way break-before make contact group in the output allows alarm signalling to operate;
• LED indicators of the mains voltage in the input and voltage in the output;
• trip/reset hysteresis for Umax/Umin is approximately 5V; it means that if the relay had tripped due to a voltage drop below Umin threshold and the load was de-energized, the relay would reset automatically and energize the load when the voltage exceeds 5V above Umin threshold (reaching the level set by hysteresis) with reset delay Ton;
• compactness, low power demand and small weight of the relay;
• mounted on a standard DIN rail.

RN-101 is socket type voltage relay. Just insert the plug and get the protection for the equipment needed.

Applications:

All single phase electrical / electronic loads.
