Share
The KINYO KYA0611A is an industrial-grade Air Conditioner Soft Start PCBA designed for recreational vehicle (RV) rooftop units, commercial heat pumps, and hermetic refrigeration compressors. By integrating onboard solid-state micro-controlled phase-angle regulation, it slashes compressor startup in-rush current by up to 70% without requiring external mechanical AC contactors, eliminating contact wear and electrical arcing while protecting generators and inverter battery systems.
Direct Factory Engineering Support
Backed by 20+ years of electronic control board engineering and PCBA manufacturing expertise. We support custom board geometries, specialized wire harness pinouts, custom voltage programming (110V/220V/wide range), and volume OEM production.
PERFORMANCE & VERIFICATION

| Overload Current Trip | Triggered > 23A / 32A | Automatic Motor Lockout |
| Under-Current Stall Detection | Triggered < 3A | Open Circuit / Stall Safety |
| Operating Temperature Range | -40°C to +85°C | Thermal Chamber Tested |
| Short-Cycle Restart Delay | 4 Minutes | Pressure Equalization Protect |
Note: Performance results were obtained under controlled laboratory conditions. Actual performance may vary depending on test conditions, compressor brand, generator capacity, and electrical installation environment. Test reports are available upon request.
ENGINEERING HIGHLIGHTS
- No External Contactor Required: Directly drives compressor motor windings via onboard solid-state switching, eliminating bulky electromechanical contactors, contact chatter, and arcing failure points.
- Up to 70% In-Rush Surge Drop: Smooth ramp-up algorithm protects backup generators, portable inverters, and pedestal breakers from abrupt locked-rotor current spikes.
- Intelligent Hardware Protection: Continuously monitors line current in real time, automatically cutting power if current exceeds 23A (overload) or drops below 3A (stall/unloaded fault).
- Continuous Self-Learning Firmware: Onboard microcontroller continuously senses motor back-EMF, dynamically tailoring voltage ramp rates across varying head pressures and temperatures.
