DC Fundamentals Unit 1 – Trainer Familiarization
Additional protective circuitswithin the base unit guard against over voltage, over current, and
reverse voltage in any circuit board; connected to the base unit.
Circuit boards are inserted into the base unit through the use of a Zero Insertion Force (ZIF)
connector.
When open, the ZIF connector allows circuit boards to be inserted without any friction.
When closed, the ZIF connector provides power and other electrical signals to the circuit board.
