FAQs
The ACS550-U1 supports Dir Connect wiring with bottom or side conduit connections, enabling flexible panel layouts and easier field installation. This reduces wiring errors, shortens commissioning time, and provides adaptable routing for retrofits or new builds. It is especially beneficial when space is limited or existing conduit openings must be reused.
Yes. The 380-500V ±10% input range accommodates a wide range of regional power quality and distribution schemes, reducing the need for transformers or voltage conditioning. This tolerance helps maintain consistent motor torque and speed control for pumps, conveyors, and fans, minimizing downtime due to voltage fluctuations in many manufacturing environments.
This drive is well-suited for medium-capacity applications like conveyors, pumps, and fans in manufacturing, packaging, and process facilities. With 1.5HP output, 3.3A current, and a broad voltage range, it supports reliable variable-speed control on standard 380-500V networks while offering robust enclosure protection for harsh plant conditions.
IP54 protection with a NEMA12 enclosure provides dust and splash resistance, reducing enclosure-related failures and enabling safer, longer service life in dusty, damp, or wash-down areas. This level of protection lowers maintenance costs, improves uptime, and supports compliance with industrial safety expectations in challenging facilities.
The drive can lower energy use through precise speed control and smoother motor starts, while simplifying installation with flexible wiring. In a retrofit, you can expect reduced commissioning time, fewer maintenance events, and extended motor life, contributing to a favorable total cost of ownership and faster payback in facilities operating on 380-500V networks.
