20BD156A3ANNARD0

The 20BD156A3ANNARD0, a part of Allen Bradley's PowerFlex 700 series, is an adjustable-frequency AC drive designed for comprehensive control of electric motors. This unit is rated for a 3-phase input voltage of 480 VAC and widely used within industrial applications. It supports standard operation at a frequency of 60 Hz while providing a continuous output current performance of 156 A, making it suitable for demanding environments.

With a motor power rating of 125 HP, this drive accommodates significant overload situations, withstanding 188 A for up to one minute and a temporary peak of 250 A for three seconds. The unit draws around 147 A during input operations, which is essential to note when considering supply capabilities.

Enclosed in an IP20/NEMA Type 1 protective casing, the drive is designed to operate effectively in environments that meet the appropriate specifications. The interface features an LCD along with a keypad, which allows users to navigate through settings conveniently. For maintaining electromagnetic compatibility, an integrated CE filter and choke are included.

The functionality of this drive necessitates an external brake, which is crucial for applications requiring precise stopping capabilities. Its control I/O supply operates at a standard input voltage of 115 VAC.

Additionally, the logic ride-through feature provides a minimum of 0.5 seconds and typically around 2 seconds of operational continuity during brief voltage interruptions, enhancing system reliability. Operating conditions should be maintained within a temperature range of 0 °C to 40 °C for optimal performance.
