Single and threephase ac drives

Single and three-phase ac drives come in sizes ranging from 0.25 to 100 hp and voltages of 115 to 575 Vac. Standard GS1 drives (up to 2 hp) feature one analog input, four programmable digital inputs, and one programmable normally open relay output.

The GS2 variable-frequency ac drives, (up to 10 hp) include models for motorspeed- control applications, which offer dynamic braking, PID, and a removable keypad. They can be configured using either the built-in digital keypad or the standard RS-485 serial communications port. GS2 drives come with one programmable analog input, six programmable digital inputs, one programmable analog output, and two programmable relay outputs.

For sensorless vector control, the DURApulse Series (up to 100 hp) offers three analog inputs, 11 digital inputs, and one SPDT relay output. They are designed for HVAC, grinders, extruders, compressors, mixing, and material handling.
