DS6 series soft start controllers
Introduction
Eaton's Cutler-Hammer DS6 solid-state soft
start controller is an electronic, self-contained
panel- or enclosure-mounted motor soft-starting
device. It provides three-phase induction motors
with a smooth start, both mechanically and elec-
trically. The DS6 line uses four silicon-controlled
rectifiers (SCRs) that are connected in a full wave-
power bridge on two phases. The voltage and cur-
rent applied to the motor are controlled by varying
the SCR conduction period. This, in turn, controls
the torque developed by the motor. After the
motor reaches speed, a bypass contactor is ener-
gized to bypass the SCRs. The DS6 is designed
to fulfill the industrial service requirements of
applications such as chiller starters, pump panels,
and machine tools. This device meets all relevant
specifications set forth by UL 508, IEC 60947-4-2,
CE, C-Tick, and CSA .
This leaflet covers basic installation and setup. No
publication can take into account every possible
situation. If you require further assistance with any
