About TPS300P DC Power Supply:

● High precision voltage, ammeter head and pure MCU digital control output for better stability and higher precision.

● Dual voltage stabilizing structure, high efficiency, low ripple, low noise output.

● Product constant voltage CV / constant current CC mode, which enables continuously adjustable output within the rated range.

● It can be converted to external control mode, external input control voltage, used to control the main power supply voltage and current output.

● It has extended master-slave parallel, series operation mode, which is more convenient for user to use series-parallel expansion.

● Provide 10 convenient and fast parameter storage functions(including OVP and OCP setting values), which is convenient for users to quickly and directly call the output.

● Provide over-voltage, over-current, over-temperature protection and alarm functions.

● Provide external monitoring function for main output voltage and current parameters.

● It has functions of storable output parameters, status lock, and alarm.

● The intelligent cooling system adopts a double ball fan to automatically control the fan speed according to the internal temperature, making it quieter and longer-lived.

● Support remote control, computer program control, standard RS232 communication interface.


Technical Details TPS300P DC Power Supply


Very versatile lab power supply up to 75V and 10A (max 300W), both in output, configuration and in protection. This lab power supply has a number of features that you will normally only find in the higher price segment.

  • The cooling is completely silent at low load and only switches on when the internal temperature becomes too high.
  • Two power supplies can be placed in series or parallel (including communication between them).
  • Various protections available: OVP, OCP with alarm option
  • External analogue and RS232 interface (default)
  • Accurately adjustable (10mV / 10mA)
