Dolphin Automatic Deep Freezer And Fridge Protector (DF) is designed to protect Refrigerator & Deep Freezer & Fridge against the hazards of over-voltage and over-current caused by under-voltage. The fully automatic operation of the Dolphin protector (DF) now enables its use at places where ordinary circuit breaker could not be used, because of tripping problems. Dolphin Dolphin Automatic Deep Freezer And Fridge Protector protects against short circuit before it occurs.
FUNCTIONAL DESCRIPTIONS of AUTOMATIC REFRIGERATOR AND
Dolphin Deep Freezer & Fridge Protector comes in an ergonomic direct-mounting palm size case.
Dolphin supplies power to the Refrigerator & Deep Freezer, as long as the line voltages remain between 161V to 265V.
In case the line voltage falls below 161V and stays there for longer than 0.3 seconds continuously, the supply to the Refrigerator & Deep Freezer will be cut-off.
Dolphin Dolphin Automatic Deep Freezer And Fridge Protector (DF) will automatically resume supply to the load once the line volts are normal. No manual intervention is needed.
Similarly, if the line voltage rises above 265V and stays there for longer than 0.3 seconds continuously, the supply to the Refrigerator & Deep Freezer will be cut-off.
Again, automatic resumption of supply to the load will take place after the line voltage is normal.
However it will wait for approximately 3 minutes to protect the compressor motor. If power is resumed after more than 3 minutes, the protector will wait for 1.5 seconds only to prevent power back surges reaching the Refrigerator & Deep Freezer.
Reset time varies with the nature of fault, i.e. bigger voltage dip causes a longer time.
One unique feature of the design is inverse delay response characteristic. The tripping time of 0.3 second reduces proportionally to the depth of under-voltage or the height of over-voltage.
When green light illuminates, it indicates that Dolphin (AAP) detects a normal Line voltage.
The light indicates Dolphin (DF) is protecting your Fridge, Refrigerator or Freezer from a damaging over/under voltage condition.
After your Dolphin (DF) has detected a damaging voltage it has delayed the resumption of power supply for approx. 180 sec. to protect the compressor motor.
