Adjustable dc power supply 

Ⅰ. Characteristics 


  • 1.   Advanced switching mode power supply -- Adjustable dc power supply technology and components, excellent design, small volume, light weight, high efficiency, which ensures the stability and reliability of long-term full-load operation.
  • 2.  Constant voltage value and constant current value can be continuously adjustable within the range 0~100%
  • 3. Digital display output voltage and output current.
  • 4. Temperature control fan, over-temperature automatic protection; output overvoltage, over-current and short-circuit protection; start up delay soft starting can avoid the overshoot voltage when start up.
  • 5.  Simple operation, convenient use
  • 6.  Store temperature: (-40~70)℃, Working temperature: (-20~50)℃
  • 7.  Relative humidity: 90% (40±2℃), atmospheric pressure (70-106)kPa


Ⅱ. Application:


It is widely used in electric power DC screen system, engineering control, communication, scientific research, charge of storage battery, and other equipments.
