GENERAL SPECIFICATIONS
The “GSP-1100” microprocessor based motor control is a 24 vdc, full “H”-Bridge, pulse width
modulation control with regenerative braking. It is designed to run 24 vdc motors and requires a 24
to 42 vdc, no-load, supply (30 to 42 vdc is usually required for Gullco products to meet
specifications), usually derived form a full bridge rectified 22-24 vac source. The required wattage
of the supply depends upon the size of the motor. These controls can operate any motor with a
capacity of up to 250 Watts (1/3 horse power).
These controls can either operate with or without a closed loop tach feed back system attached to
the armature shaft of the motor. A tach feed back is normally recommended as it allows the motor
control to constantly monitor and correct the speed of the motor providing accurate speed control
regardless of any variance in loading. Open loop (i.e. no tach feed back) may be acceptable for
manual motor operation in situations where; the motor sensor is temporarily damaged; the motor
sensor is susceptible to failure due to an exceptionally harsh environment; or where accurate
calibrated speed is not required and the loading of the motor is constant.
Various input and output ports are provided which are either optically coupled or transistor outputs.
These ports are described in detail later in this manual.
