System 1 Regulator Great Plains Electronics Designed
Model: GPE-B-18396


Direct replacement for Gottlieb System 1 power supply B-18396, designed by Ed of Great Plains Electronics and assembled to his specifications in Canada using GPE motherboard and rated parts. Warranty is with John's Jukes Ltd. (www.flippers.com)

Features of the GPE System 1 power supply:
Extensive use of power and ground planes for less electrical noise generation and better heat dissipation.
No components mounted to base plate - easy access to all components.
Screw terminal connections installed to provide optional secure connections for ground upgrade and 5 volts.
Same physical size and mounting hole pattern as original to assure easy installation.
No surface mount components used. All components are user replaceable.

Modern switching power supply for the 5 volt section:
Capable of providing up to 5 amps of power (current limited to 4 amps for safety purposes).
Includes soft-start powerup and built in short circuit protection.
Highly 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 - this regulator is drawing 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%

Output voltage adjustment provided to overcome cabling voltage loss. Adjustable between 5.0 volts and 5.5 volts. Long life, sealed cermet trimmer used for adjustment. No chance of accidently adjusting voltage too high causing possible component damage - even if the voltage adjustment trimmer fails.

Far less heat is generated by this supply under full load compared to the original power supply.
The old supply dissipated a whopping 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. Much less heat generated.

Proven series pass transistor design for high voltage section:
Uses easy to find and inexpensive components.
Power resistors are oversized to maximize heat dissipation.
Foldback current limiting for short circuit protection.
