1. This item is a new modular adjustable power supply, the first stage of switching power supply, linear power stage is it with switching and linear power supply, compared with a high accuracy, ripple, high stability, high efficiency, no high frequency radiation interference, for occasions of features. It effectively solves linear power supply, low efficiency, high calorie, switching power supply ripple big problem, is a linear power supply and switching power supply perfect combination. 2. Product is adjustable DC power supply, voltage, current, continuously adjustable, steady flow regulator with automatic conversion of high-precision DC stable power supply, the output voltage from 0 volts from the transfer, arbitrarily selected within the rated range, current limiting protection point can be arbitrarily chosen, the output power can be continuously adjustable within the rated range. Voltage, current output and settings on the LCD screen can be displayed simultaneously 3. It has improved overload and short circuit, overheat protection circuit; fanless design, quiet, no noise;shuttle design, you can easily set the voltage and current output value 4. This product adopts microcomputer control, computer link can be arbitrarily set the desired voltage and current values. Common on the market and regulating transformer relay regulated pressure regulator DC power supply, compared with a high accuracy, ripple, high stability characteristics.
