FAQ
Do I have to have an M.T.H. Z-4000™ to use DCS?
No. DCS and Proto-Sound 2.0, whether in Command or Conventional Mode, will work
with most UL-approved, AC hobby transformers, including any M.T.H. transformer, the
Lionel® ZW, and others. We do caution you not to use homemade transformers or
Right-Of-Way™ transformers that are not UL-rated and have power outputs in excess of
190 watts, as these may damage system components. Use of older transformers, like the
postwar Lionel ZW is acceptable provided those transformers are used in conjunction
with inline fuse protection as described in Chapter 1 of this manual.
What are the maximum power ratings of the DCS Remote Control System?
The TIU channels are designed to handle up to 12 amps and 190 watts each. This is the
maximum allowed by UL regulations, which we are careful to follow. Our system is fully
compatible with all UL-approved AC hobby power supplies.
What is the effect of full voltage on the lights in M.T.H. switch stands and
passenger cars?
The bulbs used in the switches are rated at 18v. They can operate at slightly higher volt-
ages, but continuous operation at higher voltages (20-25v) will reduce the average life of
the bulb and generate a lot of heat.
MTH took the precautions of ensuring that our passenger cars bulbs would work at high
constant voltages some time ago. Most passenger car bulbs are rated at 18 volts and so
will have full lives running at constant 18v loads or less; others are rated at 14 volts, so
will have slightly shortened lives if running at constant voltages higher than that. All pas-
senger cars bulbs made in the last few years have been protected against overheating in a
high constant voltage environment.
