AVR's save on the cost associated with equipment damage caused by poor voltage levels. We manufacture best-in-class copper winding automatic stabilizer in wide input range
INPUT VOLTAGE RANGE | OUTPUT VOLTAGE RANGE | CAPACITY |
---|---|---|
180 -270 Volts | 200 -240 Volts | 0.25 – 10 KVA |
145-280 Volts | 200 -240 Volts | 0.25 – 10 KVA |
110-280 Volts | 200 -240 Volts | 0.25 – 10 KVA |
90-240 Volts | 200 -240 Volts | 0.25 – 5 KVA |
Note: An output/input switch is provided on every stabilizer. Press this to ascertain input voltage at any time. This will not interfere with the working of your stabilizer. A pilot lamp indicates that the stabilizer is in operation. This switch should normally be kept on the output side.
As both high and low mains voltage can damage your electrical equipment, the Logicstat AVR is designed to monitor and correct incoming supply continuously. If the voltage rises or drops, the AVR will stabilize the output to ensure that the voltage reaching your equipment remains within the operating range of the unit. The AVR also protects your electrical equipments against voltage fluctuations. By using the AVR you will ensure a stable and clean voltage supply to your equipment. Depending on the rating of your AVR, it is suitable for all electrical and electronic appliances, including: Fridges, Photocopiers, Laser Printers, Coolers, Televisions, Satellite Equipment, Computers, Fax machines, Air Conditioners, Video Equipment, Domestic pumps
Fault | Remedies | |
---|---|---|
1) | Output voltage Unbalanced |
1. Check input supply weather all 3 phases are present. If so ; 2. Carbon brush may have worn out broken. 3.Snapped or loose; connection on input/output. Correct the same. |
2) | Output voltage Fluctuating Continuously |
i) Adjust P3 plot clockwise on the servo control card till fluctuation stop. This can be done only on auto mode. ii)The carbon may be worn out and is causing sparkling on the track. Change the carbon. iii)Check for any loose connection on the input or the output side. |
3) | Continuous Rattling/hunting Sound |
i) Adjust P3 plot clockwise on the servo controlled card. Keep switching in ‘auto’ mode. ii) The gear on the motor and the main gear mismatching. Adjust the motor by loosening it four holding screws and moving the motor to match the two gears. Tighten the motor in the correct position. |
4) | Output voltage not Regulating |
i) Put the switch in manual mode and try to raise or lower the output voltage. ii) Check if the motor is running. Incase no change in voltage occurs; the gear on the motor shaft is definitely not matching with the main gear. Please do the needful as explained above. iii) Put the switch in auto mode after correction. If still not regulating to the correct value the control card may be defective. Before removing the control card short terminal No. 5 & 6 and then check. If still no function in output voltage occurs , change the card. iv) The voltage adjust pot provided on the front panel may be open, change the pot. |
5) | Tank over – heating Beyond limits |
i) Check for overloading on all three phases. The normal temperature of the oil should not be more than 45 degrees centigrade above the ambient. If the temperature is more there may be some short in the winding. Thus, requiring a major repair. ii) The oil might have fallen due to some leakage and this can also result in overheating. |
