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.  

 University labs – Teaching students about multi-rail power supply systems.  

• Industrial Automation & Control Systems  

PLC (Programmable Logic Controller) testing – Providing 24V for relays, 5V for logic, and 12V for sensors.  

Motor driver testing – Powering control logic, gate drivers, and feedback circuits separately.  

• Telecommunications  

RF & communication modules – Powering mixers, PLLs, and amplifiers with different bias voltages.  

Optical transceiver testing – Supplying multiple voltage levels for laser drivers and signal conditioning circuits.
