The 130 Series reversing speed control is designed to provide instant
reversing, quick precise stopping or rapid cycling for a wide range of
DC motor applications. The 130 Series reversing control outperforms
other dynamic braking and reversing controls by utilizing unique zerospeed detect and dynamic braking circuits. These circuits eliminate
the contact arcing and failed braking problems associated with other
reversing and dynamic braking controls. The zero speed detect circuit
also eliminates motor plug reversing problems. In the event of a
power loss or emergency stop condition, the 130 Series control will
drop into a dynamic brake condition to safely and quickly bring the
motor to a stop and remain there until power is reapplied and a run
condition is recognized.

* With suitable external heat sink (where 130 extrusion temperature
does not exceed 70°C), maximum rating for output amps can be
increased to 10 amps D.C.
** Cycles per minute are based on typical inertia type loads. Higher
cycle per minute rates may be achieved with constant torque or low
inertia type loads. Lower cycle rates may be required for very high
inertia type loads.
