Product Introdution
PMC Model 1244 SepEx® programmable controllers
provide smooth and seamless regenerative control of separately
excited motors. An advanced MOSFET power section provides
very high efficiency, silent operation and reduced motor and
battery losses.
A P P L I C A T I O N
Curtis PMC SepEx® controllers are designed for small material
handling and other light industrial vehicles using separately excited
motors. These include low lifts, stackers, personnel carriers and other
industrial vehicles.
F E A T U R E S
? Full bridge control of the motor field allows reversing without
the use of direction contactors.
? Fully compatible with the Model 1307 Programmer for
programming, diagnosticand test information.
? Armature current controlled at all times, reducing arcing and
brush wear.
? Regenerative braking increases usable battery energy and
reduces motor heating.
? Neutral braking provides automatic braking in neutral
- simulates the feel of compression braking. Braking level
adjustable.
? MultiMode¢â allows four user selectable vehicle operating
profiles.
? Programmable to match individual separately excited motor
characteristics.
? Meets or exceeds EEC fault detect requirements with circuitry
and software to detect faults in the throttle circuit, MOSFET
drive circuits, and driver outputs.
? Vehicle speed is controlled and limited at top end via motor
field control.
? Passive regen provides vehicle speed control at any throttle
position when going down ramps.
? Linear temperature cutback on armature and field drive
current limits. No sudden loss of power under any thermal
conditions.
? Undervoltage cutback reduces motor current to maintain the
battery voltage above the under-voltage point.
? PWM drivers for contactors are programmable for pullin and
holding currents to reduce power dissipation and allow the
use of common contactors.
? HPD and SRO interlock options ensure proper startup
sequence.
? Emergency reverse (belly button) input causes immediate
reversal upon activation.
