This circuit voltage can be from 0 v, output current can be ma from 2 to 3 a continuously adjustable, set the output current, if the experiment circuit exceeds the current (including short circuit), the circuit protection immediately, not cause danger such as burning device, it is electronic manufacture's right-hand man. Like making all kinds of audio circuit friend, often due to the different working voltage and circuit have a headache, this circuit can also two series into a dual power supply, can meet the needs of all sorts of use.English manual:Feature:Input voltage: 24V ACInput current: 3A maximumOutput voltage: 0 to 30V continuous adjustableOutput current: 2mA - 3A continuously adjustableoutput voltage ripple: minimum 0.01%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 diodeNotice:Power production belongs to the high voltage large current circuit, please be sure to carefully, otherwise may cause harm to the personal safetyPackage included:1 x Adjustable DC Regulated Power Supply DIY Kit
