TECHMARTSUPP VOLATGE SWITCH PLUS (TVS+) FEATURES HIGHLY COMPACT FULLY PROGRAMMEABLE UNDER AND OVER-VOLTAGE PROTECTION OVER-CURRRENT (overload) PROTECTION TIME DELAY DIGITAL DISPLAY FAULT DISPLAY NEED FOR TECHMARTSUPP VOLTAGE SWITCH AND ABOUT (𝑻𝑽𝑺+ ) Imagine a scenario where lightning strikes a power line and creates a surge, spike, over-voltage; or a scenario where an equipment of a sub-station fails and results into sag, leading to reduced voltage and increased current that destroys your thousands of Naira worth of Air conditioners. What can you do to avoid this occurrence from happening to you? To avoid this occurrence, all you need is the Techmartsupp voltage switch plus (𝑇𝑉𝑆 + ) which offers unique protection to your air conditioning unit. What is (𝑻𝑽𝑺+ ) 𝒑𝒍𝒖𝒔? Techmartsupp Voltage Switch Plus(𝑇𝑉𝑆 + ) is a new electrical product designed to control and protect single phase Air conditioners (A/C) against electrical faults such as under & overvoltage, surge, fluctuation and over current which can destroy or disrupt the working condition of your A/C. It protects any single phase air conditioning unit rated up to 20Amps operation current. FEATURES HIGHLY COMPACT AND ADAPTABLE TVS+ is specially built and design to replace normal AC switch while adding the protective function of a voltage relay and also add over current protection to provice a perfect solution for air conditioner control and protection. It can easily replace the normal water heater switch commonly used to control air conditioners and fits the normal metal patress already installed in the wall. FULLY PROGRAMMABLE TVS+ is designed with very high level of flexibility to allow the user preset the relay to meet the specified operating voltage parameter of the protected load. These include Over Voltage (S-H) between 230V- 280V, Under Voltage (S-L) between140V- 220V and the Time One delay (S-T) between 0-900 Sec. These enable TVS+ to offer precise protection and high user friendliness UNDER VOLTAGE , OVER-VOLTAGE AND SURGE PROTECTION 𝑇𝑉𝑆 + is built with microprocessor based digital technology that digitalize the input voltage signal, analyse the value and take necessary decisions according to the installed algorithm. This enables the relay monitor the input voltage and intelligently allow only healthy voltage according to users Under & Over voltage pre-set and promptly dis connect the relay in case of fault depending on the severity of the fault. OVER CURRENT PROTECTION 𝑇𝑉𝑆 + has being built to protect air conditioners against overload and short circuit. 60% of home or office fire caused by electrical fault is from air conditioner. TVS+ is controlled by a 20A overload relay that will initiate a trip once the running current is more than 20A. For this fault, auto reclosing is prohibited as a qualified personnel is required to clear the fault before switching on the relay. TIME DELAY 𝑇𝑉𝑆 + allows the user to preset the time delay before which the protected load will come up at start and after voltage fault recovery to protect against fluctuation and frequent starting. It also have intelligent time off delay to considers the severity of the fault to determine the time off delay to prevent nuisance tripping on mild fault and ensure altra fast tripping on severe fault. DIGITAL MULTIFUCTIOANL DISPLAY 𝑇𝑉𝑆 + has digital display unit where the user see for themselves all that is going on within the switch. This displays the preset under voltage, over voltage and time delay threshold when switched on. It also displays the countdown of the time delay and the instantaneous voltage while the relay is in operation. The digital display also function when FAULTS occurs, it will blink continuously when there is an over voltage or under voltage and it will black out when in case of overload.
