Surges are transient phenomena involving built up of potential and flow of currents of magnitudes server times higher than the normal working currents and voltages resulting in partial or complete damage of equipment or reduction in life of components / equipment




TEAMLINK: VAJRA ensures that surges are handled effectively and the down time due to surges is minimised to near zero


Results of Surges :
   Replacement cost of the circuit of the equipment
   Replacement cost of the circuit of the equipment


A study conducted by the IEC in several countries revealed that the loss due to surges is 27.4%


Protects 2-wire data communication devices that connect to telephone lines (such as modems and line drivers) against surges and transients and can protect up to four devices


Improves link up time and reduces service costs by protecting telephone line data communication devices (e.g., modems and line drivers) against surges and transients within specified limits


Fast response to surges allows use with high speed data communication equipment




TeamLink VAJRA is NABL accredited LAB tested for surge protection to adhere to ITU-T K.20/K.21, IEC 61000-4-5, IEC 62368-1 standards


Product is designed & manufactured by DSL line modem OEM of near 30 years' experience who understand the line condition where his equipment is connected
