SK3323/3325/3503
Programmable Linear DC Power Supply
Programmable Linear DC Power Supply
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.
SK33XX Series Programmable DC Power Supplies have three channels, which can output maximum 50 V/5.1A electronic signal on CH1 and CH2. CH3 can output some fixed voltage signals.
SK33XX Series Programmable DC Power Supplies has 10 mV/1 mA resolution, which can meet the high requirement in the electronic products’ designing and manufacturing, repairing process.
Auto switch serial and parallel are available between CH1 and CH2 to meet maximum 100 V or 10 A requirement.
4 digit LED digital tube display can show voltage, current and power simultaneously.
