DESCRIPTION
The EZ-3micro (EZ-3u
)
is a brand new take on an old paradigm: the 3-stage timer. Using advanced
microcontroller technology, the EZ-3micro brings the simplicity of three-stage timing with reliability and
repeatability that is not available with analog timers. Unique to the EZ-3u is the ability for the user to set the
timing ranges of each stage, allowing it to be customized to your application. In addition to the standard three
stages, the EZ-3u provides an additional output – the “.1” – for starting audio players or quick activation of
valves, relays, or other DC devices.

Power Connection and Power Switch
Power to the EZ-3u controller is provided through a 2.1 mm, center-positive barrel connector (commonly used
with “wall-wart” power supplies).
CAUTION
: Check the power supply carefully before connecting to the EZ-3u; the use of a center-
negative, AC, or unregulated supply that significantly exceeds 12 VDC may damage the controller.
Before connecting power to the EZ-3u controller, ensure that it is not resting on a metallic
(conductive) surface; doing so could damage the EZ-3u circuitry and external power supply.
