Description
- Powerful Performance, Lower Startup Current : Soft starter for up to 7 Ton (84,000 BTU) RVAC & HVAC units. Equipped with magnetic latching relays, dual SCR control, Hall detection and cyclic capacitor tech. It delivers gentle startup, reducing startup current by up to 75%, cutting power surges and extending compressor service life.
- Bluetooth Smart Monitoring & Control: Connect through Bluetooth for real-time system monitoring and easier setup. The smart interface helps detect operating conditions and provides better control over your RV or HVAC soft start system.IP6 Waterproof & Heavy-Duty Protection: Built with IP6 waterproof enclosure, S72 Pro HVAC soft starter is engineered for demanding outdoor environments including RV applications, protecting internal components from moisture and weather exposure.
- Intelligent Protection for Compressor Operation: Equipped with advanced current detection technology and intelligent control algorithms, TURBRO AC soft starter helps manage compressor startup load, improve electrical efficiency, and extend AC system lifespan.
- Works with Generators, Inverters & Solar Power: Engineered for generators, inverters and limited-utility/off-grid power systems, this home AC soft-start kit cuts startup current for smooth air-conditioner performance under low-amperage conditions. It works with 2-stage compressors and heat pump units, ideal for RVs, solar setups, backup power and blackout scenarios.
- Installation Reminder: Please kindly check and remove original start components before installation. If there are PTCR and START CAP., please remove both. If there are START RELAY and START CAP., also remove both. Otherwise, these components will cause compressor startup failure or ineffective peak starting‑current control. Please contact us for confirmation before installation if you are in doubt.
