The Lenz Silver 21 decoder features a 23kHz high frequency pulse-width motor controller with configuration settings for six motor types incorporated into CV50. Further fine tuning is possible using CVs 113 and 114 with motor type settings 4 or 5. Speed curves can easily be adjusted using CVs 2,5 and 6 to set minimum, maximum and mid speed settings. The decoder automatically adapts the speed characteristics to provide a smooth acceleration curve.
Motor output 1A, 1.8A peak, 5A stall.�23kHz pulse frequency for smooth and quiet slow speed running.
Function outputs 100mA each.
Function button controlled shunting speed for improved low-speed control, with adjustable maximum shunt speed.
Fully configurable lighting effects, speed curve and braking functions.
