The Allen-Bradley 20G21RC8P7JA0NNNNN motor control drive from the PowerFlex 755TS series features advanced variable frequency capabilities supported by TotalForce motor control technology, ensuring precise and reliable operations. Designed with a Size 1 frame, it requires forced air cooling at a minimum rate of 50 CFM to maintain an optimal operating temperature range between -20 to 50 degrees Celsius, with output derating beyond this range up to a maximum of 60 degrees Celsius. The drive accommodates both DC and AC inputs with ratings of 540 Volts DC and 400 Volts AC, while delivering 4 kilowatts in normal duty and 2.2 kilowatts in heavy duty, all monitored via a built-in digital LCD screen and keypad on its front panel.
