Advanced PWM Charge Controller with LCD and Datalogging
Product Introduction
The CXup series is a powerful family of PWM charge controllers with advanced
features for 12/24V systems. Featuring a user-friendly, back-lit LCD display, USB
charging port and up to 2-years of system performance data, CXup is ideal for a wide
range of off-grid applications requiring intelligent features.
CXup units are equipped with four, robust touch-sense buttons which allow the user
to scroll through real-time data and make settings changes with ease. The built-in
USB charging port supplies power for charging mobile devices off the main system
battery. All CXup units have an optional dusk-to-dawn load timer which can be
utilized for solar lighting applications.
