MAX2024-U
20A PWM SOLAR CHARGE CONTROLLER
PWM, 20A, 12V/24V auto,
LCD display, 5V2A USB, IP32
- LCD display design, read operating data and working condition easily.
- 12/24 automatic recognition.
- Built-in over-temperature protection mechanism, the temperature exceeds the set value to the charging current drop operation.
-
Automatic limit function of rated charging current.
- Flexible System battery selection: Liquid, Gel, AGM and Lithium.
- Lead-acid battery charging in four stages:fast charge, boost charge, equalization charge, float charge.
- PWM charging is programmable to prevent system failure caused by BMS.
-
Short-circuit protection is programmable to prevent output shutdown when opening the capacitive or inductive loads.
- Small size, PID algorithm adopt to control the voltage output, make the control more stable and accurate.
- The optical control point voltage and charging voltage can be set.
- Perfect EMC & thermal design.
