The SK33XX series programmable linear DC power supplies have three independent outputs – two sets of adjustable voltage/current and a fixed set of selectable voltage1.8V, 2.5V, 3.3V and 5V. it has three available operation modes–independent, series and parallel modes. All make this series become a high performance-to-price ratio instrument.
 
Applications
Electronics Testing & Development
 Multi-voltage circuit testing – Powering different sections of a circuit (e.g., analog, digital, and RF) with separate voltages.  
 Op-amp and amplifier testing – Providing positive, negative, and bias voltages simultaneously.  
 Microcontroller & FPGA development – Supplying core voltage, I/O voltage, and auxiliary power.  
LED Testing & Driver Development 
 RGB LED testing – Supplying different voltages/currents for red, green, and blue LEDs.  
 LED driver validation – Testing constant current/voltage modes. 
Automotive & Aerospace Testing 
 ECU (Electronic Control Unit) testing – Powering multiple subsystems (sensors, actuators, communication modules).  
 Avionics testing – Simulating different aircraft power rails (e.g., 5V, 12V, 28V).  
 Research & Education
 Physics experiments – Powering electromagnets, lasers, or sensors at different voltages.
