FEATURES:

• Extensive use of power and ground planes for reduced electrical noise generation and better heat dissipation. Easy access to all components by eliminating large heat sink.

• Screw terminal connection for optional durable mechanical connections to ground.

• Same physical size and mounting hole pattern for easy installation.

• Through-hole construction for field service.

•

• SPECIFICATIONS:

• 
  

• Modern switching power supply for the 5 volt section provides up to 5 amps of power (current limited to 4 amps for safety purposes).

• Soft-start power-up and built in short circuit protection.

• Efficient MOSFET based switching supply with a >95% *measured* efficiency when providing 3.6 amps. This means that when providing 3.6 amps to the 5 volt load - regulator is draws less than 1.6 amps from the transformer.

• 
  

• Measured values:

• 
  

• Input power = 12 volts x 1.55 Amps = 18.6 watts

• Output power = 5 volts x 3.6 Amps = 18 watts

• Efficiency = 18 / 18.6 = 96.7%

• 
  

• 
  

• High efficiency design results in extended lifespan of transformer, bridge rectifier and main filter capacitor. Includes output voltage adjustment to overcome cabling voltage loss.

• 
  

• Less heat is generated by this supply under full load compared to the hot-plate design of the original power supply. The old supply dissipated 25.2 watts of power (based on 3.6 amp load). This translates to a lot of wasted power - i.e. heat. This new supply dissipates a mere 0.6 watts of power based on the same 3.6 amp load.
