Durapulse Series sensorless vector—plus closed-loop control—ac drives now expand AutomationDirect’s offerings in this category with a product reportedly so easy to set up that ”experienced users don’t need to read the manual.” Default values are set for the U.S. industrial market. Available in 1 to 100-hp models, these drives provide 175% starting torque, 150% rated current for one minute, automatic torque and slip compensation, internal dynamic braking circuit (models under 20 hp), three analog inputs, one analog output, programmable I/Os (11 digital in; 3 out, plus 1 relay), among other features. The drive’s PWM output is controlled by a microprocessor with frequencies from 0.1 to 400 Hz.
An intuitive LCD programming keypad complements the drive. It features real language pa-rameter groupings, stores up to four application programs, and is removable for remote mounting to ease data and parameter access. Durapulse Series drives also feature RS-485 Modbus serial in-terface and an Ethernet option via the company’s GS-EDRV Ethernet module, which allows ac-cess to Modbus TCP/IP or a built-in Web server. The UL/CE-listed drives come with a two-year replacement warranty. Prices range from $289 to $3,999.
