N2S Technologies Service Engineer Interview Questions and Answers

The number of IO cards used in a machine varies depending on the specific machine and its requirements.

• The number of IO cards used in a machine depends on the complexity and functionality of the machine.

• Different machines may require different types and quantities of IO cards.

• IO cards are used to interface between the machine's control system and external devices or sensors.

• Some machines may require multiple IO cards t...read more

UPS/Inverter is an electronic device that provides backup power during power outages or fluctuations.

• UPS stands for Uninterruptible Power Supply while Inverter converts DC power to AC power.

• UPS provides instant backup power during power outages while Inverter provides backup power after a few seconds of power outage.

• UPS is commonly used for computers, servers, and other critical equipment while Inverter is commonly use...read more

IGBT/MOSFET are types of transistors used in power electronics.

• IGBT stands for Insulated Gate Bipolar Transistor and is used for high voltage and high current applications.

• MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor and is used for low voltage and low current applications.

• Both IGBT and MOSFET are used as switches in power electronics.

• IGBT has a higher switching speed than MOSFET but MOSFET has a...read more

The basic component of electronics is the resistor, capacitor, and inductor.

• Resistor: limits current flow

• Capacitor: stores electrical charge

• Inductor: stores electrical energy in a magnetic field

• Diode: allows current to flow in one direction

• Transistor: amplifies or switches electronic signals

Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction

• They consist of two coils, primary and secondary, wound around a magnetic core

• When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil

• This voltage can be stepped up...read more
