WYK- series DC stabilized power supply is the use of international advanced "suspension superposition type" technology developed from. Line by a step-down transformer rectifier filter, adjust power transistor and the reference sample amplification and so on. Dual independent output power can also be connected in series or in parallel, in series from the output voltage tracking main output voltage, maximum output current in parallel up to two independent output current. The power supply with ultra-high accuracy, high accuracy, high stability and good electronic properties, in research institutes, laboratories as adjustable power supply or production line as a product life test of fixed power, it is the best choice in. Moreover, it has a perfect protection circuit, to better meet the user a simple, easy to use requirements. Compared with the switching power supply, it has a high precision, small ripple, no high-frequency radiation interference, for occasions of advantages. This power supply is available for capacitors, relays, resistors and other components for sophisticated test, it can also be used as a thermistor, electrical and other electronic components experimental testing. Currently, many well-known capacitor factory, resistors and other electronic components factory production units and scientific institutions and other R & D units, are used in this series of power, were very high appraisal.
