Decription: Features: 100% Brand new and high quality ! Input voltage: 24V AC Input current: 3A maximum Output voltage: 0 to 30V continuous adjustable Output current: 2mA - 3A continuously adjustable output voltage ripple:0.01% max All straight inserted element, make easy, only an adjustable components ( used to adjust the voltage of 0 v ) LED indicator for output over current, when the current exceeds the set data circuit protection, LED lighting, over load and short circuit protection Minimum current (2mA) under the measurable leds and zener diode All inline components, simple installation, easy maintenance The output voltage is easy to adjust The output current limiting state is indicated by the LED When the output current exceeds the limit current, it automatically switches to constant current mode, providing complete protection for overload or fault Notice: Power production belongs to the high voltage large current circuit, please be sure to carefully, otherwise may cause harm to the personal safety Due to the different monitor and light effect,the actual color maybe a slight different from the picture color. Please allow 0.5-1cm differs due to manual measurement . Included: 1 x Adjustable DC Regulated Power Supply DIY Kit
