Metal Oxide Varistor By Altek Systems

We are the authorized dealers of various manufacturers including Gujarat Poly-AVX Electronics Limited (GPAEL). We procure metal oxide varistor from it. Being a voltage dependent resistor, metal oxide varistor have fast response time and excellent voltage ratio. It's symmetrical voltage-current characteristics helps in protection of almost all types of electronic devices or elements from switching and induced lighting surges. Metal oxide varistor are widely used in the electric engineering applications due to its non linear exponent characteristics that are ideal for a huge variety of applications and assemblies. Metal oxide varistors offers excellent surge current handling capability and performs efficiently in clamping voltage characteristics. Its great voltage and energy ratio provides low leakage of current.

Metal oxide varistors are used in the following applications :
* To protect IC. Diode, transistor, thyristor, triac and other semiconductor devices
* Surge protection in communication, measuring, controller electronics and other appliances
* Relay and electromagnetic valve surge absorption.
