Phocos CML USB Charging Output Positive Grounding 10A 20A IP68 PWM 12V 24V AUTO Solar Charge Controller
The CML-USB series is designed for-low cost applications and is ideal for small solar systems in need of a low battery disconnect feature. The electronic circuit is equipped with a microcontroller that provides high-efficiency charging technology together with a number of outstanding features like status display, warning and safety functions. Leisure and rural electrification systems are the typical applications for the CML-USB controllers. They provide a perfect solution for costsensitive systems that require state-of-the-art system management.
A built-in USB charging output is ideal for charging mobile devices off a solar home system. Low-voltage disconnect prevents battery damage from deep discharging.
