I've had the Z-4000 transformer (I have 2 of them - one for accessories and one for trains) for many years now and they've always had more power than I ever needed, until recently that is. Since hooking up > 30 structures, some kit-bashed with dozens of light bulbs each (most incandescent), ~ half the structures are powered by one throttle and the other half via the other throttle, I found that the transformer is "pulsing" the lights whenever I crank up the power and the amperage > 9 amps (I know LEDs operate much more efficiently and with less power but am not installing them at this time, maybe if and when I ever retire, LOL). Side note: most structure lights will light well at 8-10 volts but the blinking signs need higher voltages and amps to work. This led me to wonder what is the internal circuit breaker in the transformer rated at? I read the instructions and could only find the following:
"The Z-4000 was designed to operate any AC-powered model train or operating accessory. The transformer contains two variable outputs, each capable of providing 180 watts to the track or accessory, and two fixed voltage outputs of 10 and 14 volts repectively. The fixed outputs are designed for powering accessories like lamps and switches, while the variable outputs should be utilized for locomotive and operating accessories. In addition, the Z-4000 features individual circuit breakers for each output and utilizes a state-of-the-art design that minimizes voltage fluctuation when bell or horn buttons are activated."
From the above, it states that each output has its own circuit breaker. What is the amp limit on these? Does anyone know?
Recalling from basic electricity course years ago P = volts x amps. If accurate, then theoretically I could crank the voltage and amps up to 16 volts and 10 amps per each throttle yielding 320 watts total. But, something tells me this will blow the circuit breaker (the pulsing lights at 9 amps may be a warning sign that the circuit breaker is going to trip). Same question applies if you're running trains on each throttle ~ command mode at 18 volts and 10 amps = 360 watts.
Last question is, what is Lionel's newer ZW transformer rated at - the big one that's been out for some years now.
Finally, I should mention that although I've read about cheaper transformers for buildings and accessories, I like the ones with variable control via throttle so that I can set lights at whatever brightness I want.
