Star Delta is a supplier of various electrical and electronic components which include transformers, motor starters, inverters, lighting transformers, variable transformers, electroplating machines, reactors, chokes and so on. Star Delta also provides motor starting auto transformers which start the motor on a lower voltage. Star Delta's motor starting auto transformers require an appropriate control system to start the motor on 50 percent, 65 percent or 80 percent reduced voltage for a short time.
Star Delta also supplies variable auto transformers which provide continuous adjustable AC voltage. Variable auto transformers are efficient and reliable method of controlling AC voltage from zero to line voltage by amplitude modulation of the AC waveform. Since the current, power, heat, light and motor speed are further functions of the voltage, the variable auto transformers provided by Star Delta find its varied use, but are not designed to provide AC mains isolation.
Star Delta's variable auto transformers provide various features which include good regulation, smooth control, high efficiency, linear output voltage, Sine Wave purity, lower input current, special voltage range and so on.
Star Delta provides a range of transformers for lighting applications which include IP 67 garden lighting transformers 100 – 400va and IP 66 lighting transformers 500 – 4,000va.
