Doehler & Haass digital decoders
The German brand Doehler & Haass is well known for their quality small decoders. The PD05A beats all competitors with its unbelievable size. Even on the picture you can not imagine how small it is.
PD05A-4 Nano decoder
With 6 pins NEM 651
You would choose this because:
One of the smallest model train decoders known to mankind.
PD05A-3 Nano decoder
With 6 wires
Can be programmed with virtually any DCC command station.
Dimensions: 5.0 x 7.9 x 2.5 mm.
Cable length around 145mm.
Driving characteristic values
Compatible with systems: DCC, SX1, SX2. Does NOT support DC-analog.
Total load: 0,5 A
Max. motor current: 0,5 A
Max. driving voltage: 30 V
LV, LR (dimmable): each 150 mA
AUX outputs: none
SelecTRIX 1 31 speed steps, 100 addresses
SelecTRIX 2 127 speed steps, 10,000 addresses, 16 additional functions
DCC short addresses (1-127), long addresses (0001-9999), with 14, 28, 126 speed steps
Load control of the latest generation, therefore particularly soft control behavior
Various control variants for optimum adaptation to the engine
Internally 127 speed steps
Adjustable motor frequency (16 kHz, 32 kHz)
Block section operation with simple diodes in digital mode
Light outputs dimmable
Motor, light and track connections electronically exchangeable
Reset function for DCC and SX2
Update capability of the decoder
New in this 2nd generation: Solder pads VS and GND can be used for as common (blue wire) or connection for condensator based Stayalive (not powerpack)
Because of the small size of the decoder, the PD05A has some limitations:
Does not support MM und DC-analog
Does not support SX1 programming (though it is still possible through SX2 parameter programming)
No SUSI connectors
No function outputs (AUX), except for front and rear light
No extended function mappings (i.e. no conditions, no initial mapping etc.)
No automatic coupling process
No brake ramp
Perfect for 009 Bachmann Quarry Hunslet!
