Original Hiland 0-30V 2mA - 3A Adjustable DC Regulated Power Supply DIY Kit Short Circuit Current Limiting Protection English manual: Description:   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. It is never afraid of the fireworks! 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. Feature: Input voltage: 24V AC Input current: 3A maximum Output voltage: 0 to 30V continuous adjustable Output current: 2mA - 3A continuously adjustable output 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 diode Notice: Power production belongs to the high voltage large current circuit, please be sure to carefully, otherwise may cause harm to the personal safety Package included: 5 x Adjustable DC Regulated Power Supply DIY Kit
