Alternator Voltage Relay (Model Mini Avr) Density: 2.1 - 2.2 Gram Per Cubic Meter (G/m3)

Alternator Voltage Relay (Model Mini AVR) FEATURES Adjustable ON/Trip Time (1-15sec) delay provided.Common setting for all the phases.Factory set ON/OFF Voltage differential (Back-lash) Unaffected by frequency variations.Positive action without chattering.Both Din rail & Screw mounting provided.Life time guarantee of the unit (conditions apply) This is a compact micro-electronic device based on latest technology. It senses the voltage supply at its terminals and operates electromagnetic relay. The relay gets energized when all the phases are above the set value and gets de-energized when any of the phases goes below the set voltage value minu's ON / OFF differential voltage (back-lash). For Model Mini AVR, differential voltage is factory set (7V for 1phase & 10V for 3phase)Adjustable ON & OFF-Time delays is provided for protection against transients. Voltage setting and time delay are continuously adjustable with the help of a knob over a linear calibrated dial. Two changes are provided for customer's usage. Auxiliary supply of 12VDC or 24VDC can be provided if required. Three LED's (Light Emitting Diodes) are provided on top of the unit to indicate-Voltage supply on',Relay on' and 'Under voltage' condition.STANDARD MODELSTHREE PHASE WITH  NEUTRAL-3PNVoltage Setting 170-220ON/OFF Differential (backlash):7 VoltsOn Time Delay 1-15 SecondsOff Time Delay 1-15 Seconds.THREE PHASE  WITHOUT NEUTRAL-3PVoltage Setting 300-400 VACON/OFF Differential (back-lash):10 VoltsOn Time Delay 1-15 SecondsOff Time Delay 1-15 Seconds.
