0-30V DIY 2Ma-3A Adjustable DC Power Supply Short-Circuit Current Limit Protection Kit Electronic enthusiasts are doing a variety of circuit experiments, the need for a good performance of the power supply to provide DC voltage regulator. Although the switching power supply with high efficiency, small size advantages, but inevitably residual high-frequency interference, and linear power supply because of its very low interference and good isolation, is still the first choice for enthusiasts and even professional manufacturers. In this case,This circuit is a high-quality, continuously adjustable regulated power supply with a voltage regulation range of 0-30V. It also includes a current output limiting circuit to effectively control the maximum output current from 2mA to 3A continuously adjustable. Let the power supply circuit test an indispensable tool, it can limit the current in the experimental circuit of the typical maximum operating current, boldly turn on the power, do not worry about failure or installation errors caused by high current damage to the experimental circuit. Technical Specifications: Input voltage: 24Vac (max) Input current: 3A (max) Output voltage: 0-30V continuously adjustable Output limiting current: 2mA-3A continuously adjustable Output voltage ripple: 0.01% (max) Circuit characteristics: In this case,All in-line components, installation, maintenance simple and convenient; The output voltage is easy to adjust; The output current limit state is indicated by an LED; When the output current exceeds the limit current automatically switches to constant current mode, the overload or failure to provide complete protection. Colour:Red Material:ABS Size:10x6x3cm Package Contents: 1 * short-circuit current limit protection DIY kit Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
