DHC-100
DESCRIPTION
The DHC-100 is rated for motors with up to 5A
running currents and comes in three versions to accom-
modate different voltage applications. The DHC-100 is
rated for 117 VAC ±10%; the DHC-100A is rated for 234
VAC ±10%, and the DHC-100B is rated for 24 VAC
±10%. The unit is easily mounted with 2 screws and is
equipped with removable screw terminals that provide for
easy field wiring. The unit's size, mounting, and screw
terminals are compatible with the AMC-100, AMC-101 and
LRC-101 series controllers - the DHC-100 can be used as a
direct replacement for those units in nearly any application.
The simple three button control (MODE, ▲, and
▼) allows the user to perform a complete set-up from the
unit itself without the need for any instrumentation. The
adaptive control feature of the DHC-100 eliminates the
need for any calibration steps. In the simplest application,
only the closed and open positions need to be set and the
unit automatically and continuously sets all other parame-
ters when placed in the AUTO mode.
CAUTION ! These units are intended to be
mounted in an appropriate enclosure to avoid
electrical shocks. High voltages are present
on the outside of the unit when power is ap-
plied. AC power should be disconnected
prior to any wiring of these units. A heater
and thermostat should be used where conden-
sation may occur.
