This ac to dc converter compatible with AC 110V/230V input voltage (manual switching), support output voltage range 0-30v and output current range 0-17A, suitable for 5V 9V 12V 24v 30v devices, max adjust voltage up to 30V; used for 1A 2A 3A 5A 8A 10A 12.5A 17A devices, max adjust current up to 17A, max output power 500W, Conversion efficiency 85% Dual digital displays for real-time monitoring of voltage/current values, support 0.01V/0.01A precision adjustment, with memory function to retain last settings after power-off/restart, avoid repetitive adjustments. Ideal for demanding applications including precision electronic repairs, LED testing, and scientific research experiments, effectively preventing equipment damage from voltage fluctuations Maintains constant voltage output (e.g., stable 12V/24V without drift) during load/input fluctuations, with strong electromagnetic interference resistance. switching power supply also features a overload protection, over-current protection, over-temperature protection, short circuit protection which can protect your device from damage. Safe and stable, suitable for newer or an experienced user This upgraded ac to dc adjustable power converter has added an OP/OUTPUT switch and CV, CC mode indicator. Enabling the OP function can effectively protect load devices and products, extend the unit life. The OUTPUT button is used to turn on and off the power output, CV and CC indicator allow you to have a clearer view of constant voltage/constant current mode This dc power supply with aluminum alloy shell and designed with multiple holes for better heat dissipation, Built-in Smart Cooling Fan, it automatically run once the temperature reach about 45 / 113F to prevent overheating and burning of circuit boards; moreover, Anti-skid pads are added to the bottom, which can also make the bottom better heat dissipation and work more stable Plug Type:US Plug,it applies to Canada, India,Mexico, Thailand, the , the Philippines,Taiwan and so on.
