❓ FAQ – Frequently Asked Questions
| Question | Answer |
|---|---|
| What's the difference between PWM, VR, VS, and S? | PWM = PWM signal speed control. VR = 0-5V/potentiometer control. VS = voltage regulation control. S = fixed speed. |
| What is the 18V model for? | Designed specifically for solar panels – working voltage 10V~24V, ideal for solar systems. |
| Can it be submerged? | Yes. IP68 waterproof – fully submersible. Also works land use (non-self-priming). |
| What is the operating temperature range? | -30°C ~ 100°C (built-in driver, external use). |
| What does constant power output mean? | Power remains stable when voltage varies within a certain range. For example, a 12V 10W pump maintains 10W from 12-18V. |
| Do you offer customization? | Yes! OEM/ODM services available – parameters customizable within max power range. Contact us! |
