The 20BD156A5AYNAND0 from Allen Bradley is classified as an adjustable-frequency AC drive tailored for complex motor control applications. This drive operates at 480 V AC and works on a 3-phase system, delivering a continuous output current rated at 156 A when under normal duty. In scenarios requiring increased power, the drive can handle up to 125 HP in regular operation and up to 100 HP in heavy-duty situations.
This unit can manage overload conditions effectively, allowing for a maximum of 188 A for 1 minute under heavy workloads and accommodating peak demands of 250 A for short bursts of 3 seconds. It is protected with a maximum breaker capacity of 450 A at 480 V, ensuring the system remains safeguarded during high-load activities.
Operating with a switching frequency that can be adjusted to 2, 4, 8, or 10 kHz, the drive offers flexibility in performance tuning. The input power requirement stands at 122 kVA at 480 V. To enhance safety, it features an overvoltage trip setting at 570 V AC, automatically shutting down the drive should voltage exceed this threshold.
The drive is housed in an enclosure rated IP20, classified as Type 1, suitable for indoor environments. Additionally, it includes a motor protection limit set at a maximum of 250 A, providing further safeguards. The logic ride-through capability ranges from 0.5 to 2 seconds, ensuring operational continuity during brief power interruptions. Local I/O is facilitated through an LCD interface with no communication module included, allowing for straightforward control adjustments.
