FAQs
The ACH531 is a wall-mounted LV AC drive with an IP20 enclosure designed for safe installation in mechanical rooms. It supports 4 kW nominal power and requires appropriate supply wiring and protective devices. Plan for remote commissioning via Bluetooth if you need off-site setup, and ensure compatible motor types and HVAC loads (fans, pumps, compressors) are within the drive’s control range.
The drive provides precise speed control for fans, pumps, and compressors, reducing overspeed and throttling losses. By optimizing motor voltage and frequency in real-time, it lowers energy consumption, contributes to lower peak demand, and improves overall system COP. This is advantageous for AHUs, chillers, and pump trains in commercial buildings.
Yes. The ACH531 is designed for HVAC loads like air handling units, pumps, and compressors, making it a strong option for retrofits where space and wiring are limited. Its built-in controls simplify integration with existing building management systems (BMS) and reduce retrofit downtime while maintaining precise motor control.
The ACH531 carries CE compliance and an IP20 enclosure rating, ensuring electrical safety and appropriate protection in standard indoor HVAC environments. The optional Bluetooth capability supports remote commissioning, which is beneficial for sites with limited access or multi-site deployments.
Expected ROI comes from shorter installation and commissioning times, reduced wiring complexity, and energy savings from optimized motor control. Remote monitoring lowers maintenance travel and service costs, while built-in features provide fault visibility that can shorten mean time to repair and extend equipment life.
