DC power supply Twintex TP4305

The TP4000 series are 4-in-1 linear DC power supplies with two fully adjustable outputs and two auxiliary outputs. In constant voltage and current operations, the power supply provides high regulation and low ripple & noise. Auto series and parallel operations double output voltage and current. Automatic cooling fan control give sufficient cooling to the power supply and minimize fan noise. The output ON/OFF control and over load & short circuit protections protect the power supply and related loads from unexpected damages. As a 4-in-1 power supply, this series provide multiple solutions for powering operational amplifier, push pull stages, logic circuit and definition systems.


  •  Four independent adjustable outputs (TP-4303/4305)
  • Constant voltage and constant current operations
  • Low ripple and noise, low temperature drift
  • Auto Series and Parallel tracking operations
  • Output ON/OFF control
  •  High efficiency, high power density
  •  Dual-color four digital panel meters
