20BD077A0NYNADN0

The Allen Bradley 20BD077A0NYNADN0 AC drive is engineered to maintain high reliability and efficiency. It works effectively with a mains voltage of 480 V, specifically for 3-phase input at 60 Hz. The model lacks a feedback system, streamlining its operation in standard applications. For communication, the drive incorporates a DeviceNet network slot, providing versatility in control systems.

Regarding performance capabilities, the unit features an output current rating of 77A under continuous conditions at a capacity of 650V DC, catering to normal duty operations. In demanding scenarios, it can handle 98A for one minute and surge up to 130A for three seconds, which aids in heavy-duty applications. The drive also includes both a CE filter and a common-mode choke designed to control emissions, ensuring compliance with industrial standards.

The unit is built with a trip mechanism for AC input overvoltage, triggering at 570V AC on the specified 480V input. To monitor thermal conditions, a heat sink thermistor is present and managed by a microprocessor to prevent overheating. Digital input latency is a key feature, ranging from 9.2 ms to 16.0 ms upon receiving start signals for the SVC motor control. Notably, the frequency accuracy of this drive is precise, maintaining an output within ±0.01% of the set frequency, affirming its capability in dynamically controlled environments.
