0-30V 2mA-3A DC Regulated Power Supply DIY Kit Continuously Adjustable Current Limiting Protection
Transformer of 220v - 24v: as I do not have 24v I have put 2 units of 12v in parallel)
Input current: 3A maximum (ensure that the transformer has sufficient power)
Output voltage: 0-30V continuously adjustable
Output limit current: 2mA-3A continuously adjustable
Output voltage ripple: 0.01% (maximum)
Radiator Aluminum Heatsink+Cooling Fan (very important so that it does not burn)
Voltage output through Banana Plug Sockets and also with a female jack 5.5mmx2.1mm.
Digital multimeter and ammeter
The output current limit state is instructed by the LED.
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.
When the output current exceeds the limit current, it automatically converts to the constant current mode, providing full protection for overloads or faults.
Including a circuit to limit output current which enables output current to be continuously adjustable from 2mA to 3A.
