Project Target

DC power supply with 3 different outputs

Specification

Input

• Wall power (AC 110 Volt )

Output 

• Constant DC +12 Volt (± 0.8V)

• Constant DC -12 Volt (± 0.8V)

• variable DC +5 ~ + 12 Volt ((± 1V))

Requirements

• Soldered circuit (the transformer must be fixed on the perfboard)

• good LOR( LOad Regulation) performance

• 4 wires for output ( +12, -12, +5~+12, GND) with approximately 20 cm single-core wire

• Sign your ID on the circuit board clearly

• You need to pass the live demo for basic power supply performance check
