The Z-4000 is one achievement Mike Wolf is especially proud of. It was several years in development in the mid 1990's. Mike assembled and personally oversaw an engineering team to produce a powerful 400 watt electronic transformer that would receive the coveted UL approval. Fan cooled with two throttles that could provide up to 10 amps each at 20 volts with corresponding digital volt and amp meters. Also, two fixed voltage accessory outlets at 10 and 14 volts respectively. Quick acting nanosecond circuit interruptors insure protection of this transformer. Another safety feature is that both throttle handles must be in the full off position for the unit to power up. The Z-4000 quickly became a dependable and worthy successor to the much loved and venerable Lionel ZW, itself a lasting icon.
