PowerShield X 1 Block

The Power Shield X series is a product of years of research into problems dealing with false overload that cause premature shut down of DCC Boosters and other Circuit Breakers. These false overloads are caused by large capacitors used in sound systems decoders or lighted passenger cars. The overload appears as a short circuit until the capacitors are charged. The logic on the new Power Shield X Series determines if the load is a true short or just an overload due to discharged capacitor.

Versions Available:

PSX-1 One Output, PSX-2 Two Outputs, PSX-3 Three Outputs, PSX-4 Four Outputs:

All Solid State Operation: Fast, solid state design with reliable quiet action….no clicks or sparks.

Adaptive Load Reset: Electronically d Electronically determines if the overload is a real short or due to excess capacitance in sound decoders or lighted passenger cars.

Boost for Low Power Systems: Some low power DCC Systems boosters need a boost when resetting.
Adding this jumper helps reset low power output systems.

Auto Stop with CV Reset: A photocell input can detect a train in the reverse section and turn off power. A DCC command can then restore the power.

Block Detection: Either a photo cell or current can be used to detect a train in a block. The photocell can turn off the block. A DCC command can then restore the power.

Over Voltage Protection: If there is an over voltage on the track caused by a DCC System failure or other power inputs the PSX will shut down and protect decoders

Wide Range of Current Trip Setting: The currents can be adjusted over a range of 1.27 to 17.8 amps.
Values can be set either with CV settings or Jumpers.

Very Low Voltage Drop: Breaker On resistance is less than 0.060 ohms, so the PSX has a low voltage drop even at high currents. Much better than detectors that use a diode voltage drop.

Manual or Automatic Reset: Automatic reset of the breaker after 2 seconds. A switch can be used for a manual reset.

Power On/Off by DCC: Turn on/off output track power with your DCC Throttle!

Outputs for LED Indicators: LEDs can be added to monitor the input/output power and the status.

System Reset: CV63=42 sets all CVs to original factory values.

Output for Audio Alert: An audible sounder can be added to the card to alert if there is a short.

Network FeedBack: To Digitax Loco Net, NCE Cab Bus and Lens XpressNet for Shorted and Occupancy.
