20BD156A3AYNADA0

The 20BD156A3AYNADA0, belonging to the Allen Bradley PowerFlex 700 series, is an adjustable-frequency AC drive designed for demanding industrial applications. It is capable of handling an input voltage of 480 V AC in a 3-phase configuration, which allows it to meet substantial energy demands. This model provides a continuous output current of 156 A at 480 V, with the capacity for brief surges, accommodating currents of up to 250 A for three seconds.

With an impressive power rating of 125 HP, this drive effectively manages motors rated at approximately 460 V. The input power is calculated at 122 kVA, with an input current of 147 A, showcasing its solid operational specifications. Efficiency is maximized through the adjustable PWM frequency, which defaults to 4 kHz but can be selected within a range of 2 to 10 kHz according to specific application needs.

The 20BD156A3AYNADA0 features a DC bus voltage range of 305–810 V DC, with a nominal value of 648 V. Protection against potential electrical faults is ensured through AC trip levels set at undervoltage (UV) of 280 V and overvoltage (OV) of 570 V. The drive also supports multiple I/O configurations including 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs, facilitating versatile interfacing options for various automated systems.

For communications, DeviceNet is built into the unit, enhancing its connectivity with other devices in a networked environment. The drive is housed in an enclosure with an IP20 protection rating, conforming to NEMA Type 1 standards, suitable for use in less hazardous indoor applications.
