Hi Calum,
The Lego train motors will draw about 750ma when stalled. So, the DZ143
can handle the worst case scenario. Most of the time however, the decoder
and motor draw only a fraction of that current when the trains are cruising.
I've been running three short trains (using one DZ143 and two DN121) on
the RCX, no problems.
BTW, the DZ143 is really nice. I posted that it made half the buzzing
noise that the DN121 makes at low speeds, but I think it's even
quieter than that most of the time. Plus, there's 4 outputs, ought to be
great for controlling some interesting lighting on a loco.
