High Torque Low Speed Inverter SP600 Complete Motor Protection Screw Compressor
High Torque Inverter
,Low Speed VFD
,Complete Motor Protection Variable Frequency Drive
Designed for easy installation, the SP600 supports both wall and floor mounting, with error‑proof pluggable terminals that save time and prevent mistakes. Its built‑in PT100, PTC, pressure sensors, and protection circuits keep your equipment safe around the clock.
With standard dual RS485 (Modbus RTU) communication, the SP600 connects smoothly to HMIs and IoT systems for smart control and one‑click startup. Covering a wide power range from 5.5kW to 132kW (380V) and 3.7kW to 75kW (220V, special order), it supports open‑loop vector, V/F, and permanent magnet motor control.
- Adaptable Installation for Any Site: Designed for both wall-mounted and floor-standing use, offering flexible placement options to suit different workshop and compressor room layouts.
- Error-Proof Pluggable Terminals: Anti-misconnection design prevents wiring errors, while quick-connect terminals significantly reduce on-site installation time and maintenance costs.
- Full-Parameter Monitoring & Protection: Built-in dedicated circuits for PT100 temperature sensors, PTC motor protection, pressure transducers, solenoid valves and cooling fans, delivering comprehensive fault detection and system protection.
- Seamless Connectivity for Smart Operations: Dual-channel RS485 (Modbus RTU) communication comes as standard, supporting direct connection to HMIs, PLCs and IoT platforms for remote monitoring, control and one-click startup functionality.
