AVT5355 C

The presented DCC decoder is an excellent alternative to expensive factory solutions; useful to railway modelers, but it is also a very good exercise for electronics and automation, because it uses an extraordinary solution for data and power transmission.

Basic information:

• recommended tension on the track: 17.20 volts
• permissible voltage on the track: 12.25 V
• maximum continuous continuous current: 1 A
• Automatic Speed Control (ARP), equivalent to ABC - revised version (10-bit)
• Paged, PoM, Direct programming
• short and long addressing
• driving in 14/26/126 steps
• improved DCC decoding (time optimization)
• HLU (under testing)
• voltage stabilization on the motor regardless of the voltage on the rails
• CV2, 5, 136 (value in Volts)
• maneuvering mode: shifting of the maneuvering key, speed reduced to the value entered in CV136, on both sides of the light white, blocking the red lights by the function output, no response to the ARP (ABC / HLU)
• Smooth acceleration and deceleration (PWM1 / 256 change, not 8/256)
• 7 function outputs, including: 2 for lighting control (after 200 mA), 2 (F1, F2) additional power (200 mA), 3 (F3, F4, F5) TTL (max. 20 mA)
• output mapping
• smooth lightening and dimming of lights
• SUSI output (during tests)
• PCB dimensions 41 ž 18 mm
• system assembled and running
