Tips: How do I calibrate a variable linear DC power supply?

To calibrate a variable linear DC power supply, follow these steps. First, ensure the power supply is off. Connect a calibrated voltmeter to the output terminals. Set the power supply to a specific voltage and turn it on. Adjust the output voltage knob until the voltmeter reads the desired value. Repeat this process for multiple voltage settings across the range. Check the accuracy at various points to identify any discrepancies. If necessary, make adjustments using the calibration controls provided by the manufacturer. Confirm the accuracy again after adjustments. Additionally, consider calibrating the current limiting function by using a calibrated ammeter and a load resistor. Document the calibration results and keep a record for future reference. Periodic recalibration is recommended to maintain accuracy.

Adjustable resistor load unit

Could you provide an adjustable resistor load unit?

ATO Responded

Sorry, we cannot currently supply an adjustable resistor load unit; we can only provide power supply equipment.

Worth every penny

This power supply is the backbone of my sensor module testing setup. Its dual outputs simultaneously power both the module and debugger. The 3-digit display clearly shows current and voltage readings, and the ±0.1% accuracy is more than sufficient for my power consumption measurements. The knob feels a bit stiff when adjusting current, but it becomes manageable with practice. The overvoltage protection is remarkably sensitive and has saved me multiple times from wiring mistakes.
