Adjustable power supply 0 - 30V and 0 - 3A

thingiverse

Voltage regulator spans 0v to 30v and current regulator ranges from 0-3A with digital multimeter and digital ammeter on hand. Tags: 0-30V 2mA-3A DC Regulated Power Supply DIY Kit Continuously Adjustable Current Limiting Protection Transformer of 220v - 24v: since a 24v transformer is not available, two units of 12v are connected in parallel) Input current: 3A maximum (verify that the transformer has sufficient power to handle this) Output voltage: 0-30V continuously adjustable with precise control Output limit current: 2mA-3A continuously adjustable with fine-tuned settings Output voltage ripple: 0.01% (maximum allowed) Radiator Aluminum Heatsink+Cooling Fan is crucial to prevent overheating and burnout Voltage output connects through Banana Plug Sockets as well as a female jack 5.5mmx2.1mm. Digital multimeter and ammeter are included for precise measurements The output current limit state is indicated by the LED light, which warns of over current when it exceeds set data circuit protection, overload and short circuit protection minimum current (2mA) under measurable LEDs. When the output current surpasses the limit current, it automatically switches to constant current mode, providing comprehensive protection against overloads or faults. A special circuit limits output current, allowing for continuous adjustment from 2mA to 3A.
