INTRODUCTION
Voltage fluctuations can have a serious detrimental effect on motors, compressors, electrical and electronic quipment, reducing or eliminating their effective function, and very commonly, causing damage to the appliance. Now, there is a solution to this problem...
Vener7 Digital Voltage Stabilizer
The WS has been designed to provide a clean, regulated AC power supply to all equipment in environments with unreliable, fluctuating mains supply.
Operation
The WS monitors the main voltage continuously. If the voltage rises or drops the VVS will stabilize the output to ensure the voltage reaching your equipment remains constant at 220V (6%) and 220V (+9% in ER) within the operating range of the unit. (See Input and Output Voltage Response on Page 4)
If the input voltage falls below or rises above the input voltage range, the WS will disconnect the output, thereby protecting the load. Once the mains voltage returns again within acceptable limits, the VWS will reconnect the output following a start up delay.
Application
The WS is suitable For all electrical and electronic appliances. It is particularly useful for Fridges, Air Conditioners, Freezers, TV, Hi-Fi equipment, Microwave Ovens, Washing Machines, Air Coolers, Water Coolers, Photo Copiers, Fax Machines, Computers, Laser Printers and even Domestic Main Line.
Microprocessor Controlled Circuit
Using superior microprocessor controlled circuit the VWS is virtually the most powerful, intelligent and feature packed Digital Voltage Stabilizer available.
Cutting Edge Digital Technology
With the use of latest digital technology that is backed by its own intelligent decision making, the WS takes the concept of control and precision of electric output to an unmatched standard of perfection.
Fault Detection System
The VVS analyses its own working at all times by sensing if the measurements being made are unreasonable and disconnects output. Therefore it offers maximum protection to the connected equipment. Red and yellow LEDs flash alternately to indicate a fault.
Output Accuracy
The WS owing to its superior design keeps the output voltage within 6% range, thus making it suitable for sensitive equipment to be run safely even while running on generators.
Low noise filtration
Frequency and voltage measurement smoothing in software to filter noise that is conventionally associated with stabilizers.
PRODUCT FEATURES
Zero Voltage Switching ZVS" Technology
The ZVS technology incorporated by the VVS Voltage Stabilizer sends the competition to the prehistoric times. The Microprocessor of the VWS switches the relays at the zero point of voltage and current in the AC cycle with precision which does not harm the equipment unlike conventional stabilizers and also reduces the wear and tear of the relays increasing the life of the stabilizer manifolds.
Feedback System for Voltage Correction
The WS Voltage stabilizer operates on a closed loop feedback system with output voltage as a reference for voltage correction and cut-off. This feature ensures that the output voltage is independent of the load on the stabilizer and that it always stays within the specified range.
Intelligent Time Delay System ITDS
A wait period of 3 min is provided with this feature between each main failure and the restart of the stabilizer whereby the safety of your connected equipment is totally ensured. What ITDS does is that when the voltage input goes beyond the limit of the stabilizer, it automatically disconnects the load and protects the equipment from getting damaged. During this 'OFF' period, the microprocessor of the VVS analyses the output voltage and reconnects the lood after 3 min to allow the compressor gases to neutralize. But the intelligent microprocessor of the VVS reconnects the equipment within 30 sec when the cut off is for more than 3 min.
Overload Protection
The transformer and the circuit of the stabilizer The VVS also incorporates Overload Protection, since overloading has the potential to damage The VVS uses a fuse or MCB to do this job and extends further protection to your equipment.
Fast Response
Lightning fast response of 750 Volts/sec to voltage variations safeguards expensive equipment from damage, instantaneously.
Spike & Surge Suppression
In keeping with its commitment to protect your equipment, the VVS suppresses spikes and surges in the input and offers complete protection to the connected equipment as well as the stabilizer.
Fire Resistant ABS Plastic Casing & Powder Coated Chassis
The VVS Voltage Stabilizer comes in a robust fire resistant ABS plastic casing and powder coated steel chassis for enhanced safety and looks.
