10 Amp Power Booster recommended for O, G and other large scales ONLY. The PB-110A provides true 10 Amps of continuous voltage to your track. Enough to handle MUs of the largest locomotives.
The correct power supply for the PB110a is the 18vac 10 amp Brutus transformer.
For use with PH-Pro 10amp System or PB110 10amp Booster ONLY.
The 4 pin plug on the front should be Red,Orange,Black,Gray from left to right. To provide the needed current capacity Pins 1 and 2 are grouped together, 3 and 4 are also grouped together. The photo shows the pre wired 4 pin plug included with the 18VAC /10 amp Brutus. Factory set to 18v PWM DCC out, but can be adjusted from rear of box. You need 6 volts of in / out headroom for when using a DC Power Supply. However, The PB110a is limited to a 22V PWM track output for NMRA DCC conformance. You can use up to a 32VDC input if needed.
Example: A 24VDC Supply will give you 18V PWM on the rails at full load.
