Adinath Controls Automatic Thyristor Power Controller, For Industrial

From the day of commencement, we are engaged in manufacturing, supplying, trading and exporting Thyristor Power Controller. A thyristor is a semiconductor device which acts as a switch, which passes current in one direction, when it is switched on and to switch on the alternative current, two devices should be connected in inverse parallel. To meet the variegated demands of customers, these controllers are available in different specifications as per the needs and requirements of customers. The Thyristor Power Controller offered by us is available at market leading prices. Other details:Thyristor units start at 3ASizes up to 2600A and 690VacProducts Variety:Three Phase (2PH) 2-leg:Single Phase Thyristor Power Controllers:A range of thyristor power controllers to switch single phase loads.Ideally suited for normal or variable resistive loads and transformer & inductive load typesEach device is turned on at the appropiate time by a trigger pulse applied to the gateThe device will remain on until the instantaneous load current through it drops to zeroThe trigger pulses are generated by a driver, which times the pulseEnsures the thyristor unit output is a function of the input demand signal firing modeThe Basic Firing Modes:Zero Crossing (ZC):Used with the logic output from a temperature controllerThe cycle time is determined by the temperature controllerZC minimizes interference due to the fact that the thyristor unit switches ON and OFF at zero voltsBurst Firing (BF):This firing is performed digitally within the thyristor unit at zero volts, producing no EMC interferenceAnalogue input is necessary for BF and the number of complete cycles must be specified for 50% power demandThis value can be between 1 and 255 complete cycles, determining the speed of firingWhen 1 is specified, the firing mode becomes Single Cycle (SC)Single Cycle (SC):SC is the fastest zero crossing switching methodAt 50% input signal, one cycle is ON and one cycle is OFFAt 75%, 3 cycles are ON and one cycle is OFFIf power demand is 76% the unit performs the same as for 75% but every time the unit switches ON the microprocessor divides 76/75 and memorizes the ratioWhen the sum is one the unit delivers one cycle more to the loadWith this firing it is necessary to have an analogue inputSC is ideal for simple resistance loadsThermal mass of the load is small or as a low noise alternative to PA firing with some applications
