Allen Bradley 20BD077A0NYNANC0 PowerFlex 700 AC Drive 77 A 60 Hp 20B

The 20BD077A0NYNANC0 PowerFlex 700 Adjustable Frequency AC Drive is a digital PWM AC drive from Allen Bradley is designed to provide outstanding control to 3-phase induction in critical applications that require accurate speed and torque control. It features a space-saving drive design with integral components that use minimal space, and it is enclosed with an indoor/outdoor NEMA/UL 1 enclosure that is built to supports conventional panel mounting and zero drive stacking. The 20BD077A0NYNANC0 has an output drive rating of 60 Horsepower with 77 Amp nominal current rating at 480 Volt AC input, and it has an acceptable range within -/+10% of drive voltage class. It has a power factor of 0.98 (across entire speed range), with 97.5% PWM control efficiency, and it provides short-circuit protection of up to 200,000 Amps using circuit breakers and fusible devices.

The 20BD077A0NYNANC0 offers fast-acting current limiting and BUS voltage regulation for maximum performance, and it provides ground fault sensing as well as ground fault protection using field installable metal oxide varistors. It offers trip-less operation using high inertia rotational energy and it can provide instantaneous start to rotating motor without losing motor profile. It has enhanced motor control with 24 Volt DC digital I/O control, and a 0.1% speed regulation along with a 120:1 performance range. The 20BD077A0NYNANC0 is built to provide precise, accurate and repeated control using Sinusoidal PWM control signal with a variable carrier frequency, and provides speed control by varying motor output frequency and voltage. It offers users multiple programmed stop options depending on application needs, and it has dual acceleration and deceleration times programmed independently from 0 to 3600 seconds in 0.1-second increments. The 20BD077A0NYNANC0 offers 20 to 160% overload capacity and can provide class 10 motor overload protection. It has an operating temperature ambiance of 50 degree Celsius and can be housed within an IP20 (NEMA/UL 1) enclosure.
