Purpose/Application Areas

MCH-300D-II dual power supply series, the power supply is an adjustable multi-function high stability DC regulated power supply. Continuous output at full load, output voltage and current are continuously adjustable within the standard range. High-performance low-wave low-heat copper ring performance transformer Dual 30V5A adjustable Series 60V5A adjustable Parallel 30V10A adjustable Positive and negative voltage output.

Instructions For Use

1. Port connection: Output channel 1 and output channel 2 are floating. The negative terminal of the fixed output 5V2A is internally grounded.
2. Voltage setting: Adjust the voltage knob to get the required voltage.
3. Current setting: Adjust the voltage control knob counterclockwise to get a smaller voltage value. Short the output and adjust the current knob to the desired current value.
4. Use in series: Select the series mode by function key (both at the same time, the two sides are used independently, the left side is pressed in series mode, the left and right are pressed simultaneously in parallel mode), the "+" end of output channel 2 and the output channel 1 are used. The "-" end serves as the output. At this time, the output voltage is the sum of the two power supply voltages.
5. Parallel use: Select the parallel mode through the function button, and use any power supply as the output terminal. At this time, the output current is the sum of the currents of the two power supplies.
