Features:
BC154, BCWD140 and BC160 are non-regen controls with reversal
by means of switching the armature leads (BCWD140 has a forward/brake/
reverse switch mounted). BC254 is a line regenerative SCR control that can
drive the motor to a timed stop. BC354 is a PWM control that provides low-
ripple DC power to the motor allowing more Hp when used with a 130 or 260
VDC motor. All offer a choice of armature or tachometer feedback and a speed
or torque mode. No Hp resistors are needed for these controls, current is jumper
selectable. BC154, BC160, BC254 and BC354 are painted black and come with
a start-stop switch. BCWD140 comes with white epoxy paint and also forward/
brake/reverse and run-jog switches. See page 330 for features.
