SCR/DC Variable Speed Motor Controllers

Acrison's Model 060
SCR/DC Variable Speed Motor Controller
For use with Acrison's Volumetric and Gravimetric Feeders

Overview

Acrison's Model 060 is an industrial-duty, variable speed SCR/DC motor controller providing accurate and dependable speed control of direct current (DC) motors used primarily as variable speed drives for Acrison's various model feeders.

Utilizing latest state-of-the-art digital and microprocessor technology (certified to UL, CSA and IEC specifications), Acrison's Model 060 SCR/DC Motor Controller has been robustly designed to ensure years of dependable, trouble-free service, even in the harshest environments. From its streamlined appearance, to its electrically isolated I/O, to its ease-of-use, the Model 060 provides exceptional precision in controlling the speed of fractional to 5 horsepower DC motors.

The Model 060 is available in two sizes. In one configuration, the Model 060 will control DC motors ranging from 1/8 to 1 horsepower (inclusive). In a second configuration, the Model 060 Controller will operate 2 to 5 horsepower DC motors. The standard enclosure for each configuration is dust-tight/water-tight. Optional mountings and enclosures are also available.

The Model 060 Controller will operate with either armature or tachometer feedback, with the motor speed regulation for each mode of operation described under "Specifications."

Acrison's Model 040
SCR/DC Variable Speed Motor Controller
For use with Acrison's Volumetric and Gravimetric Feeders

Overview

Acrison's Model 040 is an inexpensive, industrial-duty, armature feedback, variable speed SCR-DC motor controller providing dependable speed control of direct current (DC) motors used primarily as variable speed drives for Acrison's various model feeders.

The Model 040 Controller's NEMA 4 (IP-65) Enclosure is designed for applications requiring washdown water-tight integrity. Its housing is ruggedly constructed of die cast aluminum which is protected with an acrylic coating for the ultimate in corrosion resistance. All switches are sealed with rubber boots and the main speed potentiometer contains a shaft seal.

The Model 040 Controller is available in two configurations: the Basic Model 040, which includes the standard features below, and either an Analog Input Module or a Serial Communication Module. The Analog Input Module provides isolation and accepts either 0-25 VDC, 0-120 VDC, 1-5 mADC, 4-20 mADC or 10-50 mADC. The Serial Communication Module provides current loop serial communication to interface with an Acrison weigh feeder controller. Both options utilize an Auto/Hand switch for either manual set pot control or automatic control from the external source.

Standard Features
Power On, Current Limiting and Stop LEDs
Electronic overload protection
Current limiting
Armature feedback
Adjustable minimum and maximum speed settings
Adjustable IR compensation
Adjustable acceleration and deceleration settings
Enclosure is NEMA 4X and IP-65 washdown and water-tight for indoor and/or outdoor use
UL, CSA and CE certifications
