3-Stage Alternator
271
The Model 271 3-Stage Alternator offers reliable sequencing for triplex systems. This device ensures balanced wear across multiple pumps or motors through its first on-first off operation. It directly replaces mechanical alternators, simplifying system design and maintenance. With a low power consumption of 0.05W and robust transient protection of 2500V for 10ms, it provides consistent performance. The unit requires no calibration or adjustments, streamlining installation. Its compact design, measuring 3.00 inches in length, 3.88 inches in width, and 6.06 inches in height, allows for integration into various control panels. This alternator is designed for sustained operation in industrial environments.
