Specifications
The motor mounted speed control is designed for 1/8 HP, 90VDC motors with a maximum current of 2.5 Amps. It operates with an input of 115VAC at 60Hz and outputs 0-90VDC. The enclosure has an IP 30 rating, and the unit is non-reversible. It is compliant with CE and ROHS standards, with UL/CUL pending.

Operational Specifications
The device supports an input voltage of 115 VAC at 50/60 Hz and a maximum output voltage of 90VDC. The output horsepower range is 1/8 HP.

Feature Specifications
The speed control offers a speed range of 20:1 and includes an on/off switch. It is designed for easy field mounting on Bison PMDC motors, featuring an aluminum extrusion for heat dissipation and a simple knob for operation. Three adjustable potentiometers allow settings for minimum RPM, maximum RPM, and current limit. A pre-wired three-foot power cord with a NEMA 5-15P plug is included.

Features and Benefits
The device is easy to mount and assemble, allowing quick field deployment. Speed is controlled via a simple on/off potentiometer, with settings for current limit, minimum speed, and maximum speed. The all-metal enclosure ensures durability and efficient heat dispersion. SCR circuitry provides consistent speed under varying loads.

Installation Instructions
Terminals L1 and L2 are factory-installed and should not be altered. Terminals A1 and A2 supply motor armature voltage. To reverse motor direction, switch the A1 & A2 terminal leads.

Calibration
Minimum RPM (MIN RPM): Adjust the MIN RPM trimpot to set the motor speed when the potentiometer is turned full counterclockwise.
Maximum RPM (MAX RPM): Adjust the MAX RPM trimpot to set the motor speed when the potentiometer is turned full clockwise.
Amp Limit (AMP LIM): Determines maximum torque. Factory set at 2.5A. Calibration involves using a DC ammeter and adjusting the AMP LIM trimpot to 150% of the rated armature current.
