Traditionally, the direct power charge from a typical vehicle engine or motor boats was used to directly to charge auxiliary batteries or back up batteries whilst driving or starting the engine. It is a good thing that your battery will be recharged every time you start your automobile engines and you don’t have to be bothered about shifting your heavy lead batteries from your cars and charge it from another source. Quite convenient right? Well, this direct wiring from the alternator to the batteries also has its disadvantages. The fluctuating voltage from the automobiles especially during ignitions and turning off the engine can produce unequal voltage supply which affects the battery life which is directly connected. This unequal supply of power can cause various issues such as over-charging of your battery which might lead to short circuiting or even explosions or, due to the direct connections, sometimes your battery can be drained for some unnecessary usage if not disconnected properly. Well thanks to VSR (VoltageSensitive Relay) technology for solving these issues.
VSR or Voltage Sensitive Relay is a relay device used in modern electrical wiring. Putting the functions of VSR in simple words, it is a device with a preset voltage with power cut off (normally from 12V to 24V range) which are installed in automobiles or any electrical engines connected with their auxiliary batteries. VSR is an automated sensor of electric voltage which is coming from any source of power engine. With its presents, VSR will automatically charge any auxiliary batteries connected to it when it senses alternator charges from any power source. For instance, if a voltage more than 12V passes the electric circuit connected to VSR, it will start getting to work and will start charging any batteries (can be two or more) contributing equal amount of charge at the same time. And for instance, the engine stops and the power supply go down below 12V, VSR will automatically disengage or disconnect from the circuit preventing the battery from draining. Also, it the power voltage crosses more than its maximum preset, it will automatically disengage as well preventing the battery from over charging. Now that’s a problem solved, right?
Most of our modern engines and automobiles are now VSR installed but if you are the old school and classy kind of person, who is still holding onto your old gadgets and cars, make sure you improvised or customised with VSR wiring and make your engines classier.
