OVCD- Over Voltage Cut-off Device

Only protection device for protection against neutral open and double phasing protection

Most of the equipments today are having power supply which can handle fluctuations between 170V to 270V.  Also a lot of equipments have built in over voltage protection. 

However there are accidental cases where trees fall on over head wires or accidentally neutral opens  and resulting fault causes voltage in single phase to shoot upto 440V. The in built over voltage protection of  any equipment is of no use , because they get damaged themselves. OVCD is protection device for protection against such problems of  neutral open or double phasing.

If you look at the pictures above you can see a typical distribution line problem. There is chance of wire sagging and over head wires touching each other . this can easily cause double phasing condition.

OVCD cuts off the supply to equipment whenever there is such a problem and connects the supply only when the voltage comes back to normal.

It effortlessly withstands voltage fluctuations up to 440 Volts and spikes up to 6000 Volts. It is programmed with a power-on delay of 3 seconds (configurable) for initial surges which are harmful to any other device.

 

Why should you consider using OVCD before your equipment?

1.No problems due to voltage fluctuation.

2.Zero downtime

3.Your equipment becomes more rugged

4.Less service calls = Increased profitability + Increased credibility.

5.Better perception of quality of your system in the minds of the customers

6.Increases the chances of repeat sales or referral sales.

USP:

Now you can install your equipment in the worst electrical conditions without being bothered about service calls.

How it works.

OVCD is connected at before the equipment in use.

Incoming current will first pass through OVCD then into the equipment. OVCD continuously monitors the line voltage.

Whenever the voltage is above or below the set voltage limits the OVCD simply cuts the voltage to the equipment thereby saving it from the line disturbance. It reacts within fraction of second to the disturbance. OVCD will withstand the voltage even as high as 440 Volts.It however does not stabilize the voltage as in the case of other devices in the same category like Stabilizer, CVTs.

When the voltage returns to normal , the OVCD resumes the supply to the equipment with short power-on delay of 3 seconds(configurable). This feature is called the Smart Start. It prevents the initial harmful transient that may damage the Equipment.

 

How is OVCD better than other power conditioning / protection products?

1.Superior protection

2.Occupies less space

3.Lightweight

4.Transformer less design

5.Portable.
