Power Specifications

Question 1

AMP

Answer 1

• Ampere (AMP, A)

- The rate of electrons flow past a point in one second

Question 2

Volt

Answer 2

• Voltage (Volt, V)

- Electrical pressure pushing the electrons

Question 3

Watt

Answer 3

• Watt (W)
• Measurement of real power use
• Volts x Amps = Watts
• 120v x 0.5a = 60watts

Question 4

Current

Answer 4

• Alternating current (AC)
  
  • Direction of current constantly reverses
  • Distribute efficient over long distance
  • Frequency of this cycle is important
• US/Canada = 110-120 volt AC (VAC) 60 Hertz (HZ)
• Europe = 220-240 volts AC (VAC) 50 Hertz (HZ)
• Direct current = One direction & Constant voltage

Question 5

Voltage Rails

Answer 5

• Single Rail
  
  • A single 12volt rail power supply
  • One output circuit generating 12volts
• Multiple Rails
  
  • Multiple 12volt power supply
  • Each rail has separate circuitry inside
  • Each 12v connector on the outside is connected to one of the rails

-Multiple Rails provide additional protection

Question 6

Power Supply Connectors

Answer 6

• Fixed Connectors
  
  • Connects to the power supply
  • May have more or less than you need
• Modular
  
  • Add cables as needed
  • Fewer leftover cables, better airflow
  • More expensive
