GSK-4

The GSK-4 is an easy to assemble basic power supply kit based on 7805 voltage regulator. This finished kit will yield two DC voltage outputs. One is a fixed regulated 5V at 1A for TTL use and the other output is variable from 5V upwards. The maximum output voltage depends on the input voltage. The specified maximum input DC voltage to the regulator is 35V and the minimum input voltage must be 2 volts higher than the regulated output voltage. The GSK-4 kit is perfect for learning basic power supply operation.

• 3 connections (input, output and ground) and it provides a 5V fixed output
• Single sided printed circuit board for component assembly
• 500R potentiometer is used to vary the output voltage from a minimum of 5V to maximum DC voltage
• Capacitor across the output improves transient response
• Large capacitor across the input is a filter capacitor to remove ripples in rectified AC voltage
• LED for circuit working condition indication
