Features

Continuously Adjustable Output: The DC power supply provides continuous 0–1000V DC output, with 2A, 3A, and 5A current options. Voltage and current are continuously adjustable from zero to rated values to meet various high-voltage DC power requirements.
Automatic CV/CC Switching: The variable DC power supply automatically switches between constant voltage (CV) and constant current (CC) modes according to load conditions, providing stable voltage or current regulation for different testing applications.
PWM Switching Technology: Advanced PWM switching control gives the power supply high conversion efficiency and stable output performance compared with conventional linear power supply designs.
High-Stability Output: The power supply features voltage stability of ≤0.5%+10mV and load stability of ≤0.5%+30mV, helping maintain consistent DC output under changing load conditions.
Low-Ripple Output: With ripple as low as ≤0.8%+10mVrms depending on the model, the power supply provides cleaner DC output for electronic testing, R&D, and precision power applications.
Multiple Protection Functions: Built-in OVP, OTP, overload, and short-circuit protection help protect the power supply and connected loads against abnormal operating conditions.
Soft-Start Output: The adjustable power supply uses a delayed soft-start function to reduce output voltage overshoot when powered on, improving startup stability and protecting connected equipment.

Tips: How to choose the output range of a DC power supply?

Choose a DC power supply with voltage and current ranges covering the actual load requirements with reasonable headroom. Set the voltage range about 10%–20% above the rated load voltage and the current range 20%–30% above maximum demand, allowing more margin for loads with inrush current. Also verify the power limit at the required voltage and current, and consider CV/CC modes, derating, ripple, noise, resolution, accuracy, and required communication interfaces.

Existing reviews of 2A/3A/5A 1000V Adjustable DC Power Supply

I highly recommend this DC power supply

The voltage and current behind the front panel of the power supply is very easy to adjust. We had a minor issue with the overlay on the front panel, but after-sales support worked with us to resolve the issue. This is enough for me to support ATO DC power supply.
