The Electronic "E" Unit provides direction sequencing of locomotives that are designed to operate with AC track power.
Our Electronic "E" Unit provides the user with greater control at slower speeds since it is completely solid state! There are
no relays to activate or drums to turn yielding positive control with power engaged to the motor with minimal track voltage.
These Electronic "E" Units are designed to provide sequential direction control for the later locomotives with permanent
magnet DC motors as well as series AC motors. Item #1400 is the grand daddy of all three types of E-Units. It will power
earlier series AC and permag DC motors with up to twelve (12) amperes of current! It is the ideal unit for multiple motored
engines, and standard gauge units, requiring that extra power handling capability. Item #400 powers earlier series wound
field type AC motors as well as DC motors. Item #400 will handle four (4) amperes of current flow, sufficient for some dual
motored locomotives. Item #518 is limited to two (2) ampere and is intended for smaller locomotives with single DC
motors. While most operators will use AC track power, these "E" unit's will also sequence with DC track power.
The initial "power on" state is user selectable so you can decide if you want the locomotive to start in either FORWARD or
NEUTRAL. Provision is made so that a switch (item 524, not supplied) can be installed to lock the "E" unit in its initial
state. Lock in FORWARD for automation applications or lock in NEUTRAL to allow sound systems to function with a static
locomotive. If power is off for approximately 6 seconds, the "E" unit will reset to its initial "power on" position. The "E" unit
was also designed for easy installation of accessory items such as lighting. Many lighting variations are possible and easy
to incorporate because of the design of this "E" unit. Complete installation instructions are included with the unit. Lighting
variations are shown on page 2 of the 400 "E" unit which is available on our web site. As with all of our AC product line,
this unit is compatible with all types of acceptable AC track power. These units offer superior operation over previous older
units as well as other manufacturer's.
Item #518 and #400 come equipped with appropriate wire harness to plug into the E-Unit headers. Item #1400 has a
clamp style barrier strip to connect your wires. All units contain a 2 pin wire harness to connect to the lockout input.
