Power Shield X
The Power Shield X series is a DCC Power Management device. The PSX will handle the increased inrush currents which occur due to large capacitors used for sound systems. This load appears as a system short circuit until the capacitors are charged. The logic in newer PSXs determines if the load is a true short or just an inrush overload.
The Power Shield X (PSX) is the continuation of the Power Shield series of power management devices.
There are several versions of the PSX:
- PSX-AR, with integrated stall motor decoder
- PSX-ARFB, with network feedback
- PSX-ARSC, with integrated snap switch decoder
- PSX-ARSCFB, with network feedback.
- PSX-AR-AC, for 2 rail AC.
The PSX series also includes 4 DCC power district circuit breakers. They are identified as PSX-x, where the x indicates how many blocks they can control, from 1 to 4.
Compatible with 2 Rail AC.
- Automatic Coordination of Auto Reverse and Circuit Breaker Tasks: It is both a auto reverser and a circuit breaker. Fast, all solid state design with reliable quiet electronic reversing, no blinks, clicks or sparks!
- Adaptive Load Reset: Electronically senses if the overload is a real short or due to in-rush capacitance of sound decoders.
- Automates Reverse Loop Turnouts: Integrated stall or solenoid decoder, automatically lines up turnouts when the polarity reverses. Switch machine can be controlled accessory commands or push buttons as well.
- Manual or Automatic Reset
- LEDs can be added to monitor; input/output power and status.
- Trip currents adjustable by jumpers or CVs: 1.27 to 19.2 A
- A single CV command sets all Addresses and CVs to original factory values.
- An audible sounder can be added to the card to alert you when there is a short.
- Low Current booster reset if needed
- Auto Stop with CV Reset: A photocell can detect a train in the reverse section and turn off power. A DCC command can then restore the power
- Board size: is 5 3/4 by 3 3/4 inches
PSX-ARFB and PSX-ARSCFB
All of the PSX-AR features plus
- Feedback: Shorted and Occupancy Status to Digitrax (LocoNet), Lenz (XpressNet) and NCE (CabBus)
- Block Occupancy Outputs: Indicates block is occupied or shorted
- Occupancy Amps adjustable
All PSX series devices also include network feedback
