- Compact and portable: 3.94" x 2.36" x 0.79" (100 mm x 60 mm x 20 mm), designed for easy transport and on-desk use. - Voltage output: DC ±10 V with 0.01 V precision. Adjust the output with the encoder knob and calibrate as needed. - Current output: 0-22 mA with 0.01 mA precision. Adjust the output with the encoder knob and calibrate as needed. - Display and control: press the small button to switch the display mode between voltage and current. You can also switch to 0-100 percent or 0-50HZ display as instructed. - What you get: a precise, adjustable source for powering and testing circuits and sensors, with quick knob control and calibration capability in a compact package. - Use scenarios: - Electronics lab bench: power and tune a low-noise sensor or op-amp circuit within the specified voltage and current ranges. - Sensor and microcontroller testing: simulate loads up to 22 mA while monitoring voltage in real time. - Education and demonstrations: illustrate voltage/current adjustment and display mode changes in hands-on electronics classes.
