Air Compressor Integrator Inverter
Product Overview

The SP600 series is a dedicated integrated inverter designed for air compressors, supporting both wall mounting and floor standing installation. It adopts error‑proof pluggable terminals for fast and reliable wiring. Built‑in detection and protection circuits integrate PT100, PTC, pressure sensors, solenoid valves, and fans, enabling comprehensive monitoring and safe operation. Equipped with dual‑channel RS485 (Modbus RTU) as standard, it supports HMI and IoT expansion for easy one‑click startup.

Power range:

220V: 3.7–75kW (special order)

380V: 5.5–132kW

Control modes include open‑loop vector control, V/F control, and PM motor support, with a wide frequency range up to 599Hz, delivering stable performance and high efficiency for industrial air compressors.

Product Advantages
  • Flexible Installation Options: Supports both wall-mounted and floor-standing configurations to adapt to diverse on-site layouts.
  • Error-Proof Wiring: Features pluggable terminals with anti-misconnection design for fast, secure, and mistake-free installation.
  • Comprehensive Integrated Protection: Built-in detection and protection circuits for PT100, PTC, pressure sensors, solenoid valves, and cooling fans, ensuring full monitoring of key system parameters.
  • Smart Communication & Control: Equipped with dual-channel RS485 (Modbus RTU) as standard, supporting seamless HMI and IoT expansion, enabling one-click startup and intelligent operation.
