The CY-K40A PWM controller enables charging of Pb, Li-Ion or LiFePO4 batteries with a current of up to 40A and connection of PV panels 18V (for system voltage 12V) or 36V (for system voltage 24V) up to 480W (960W-24V). It is equipped with an LCD display for setting and displaying operating parameters.


Product parameters:

PWM solar controllers connect solar panels directly to the charged battery and after reaching the set or given terminal voltage of the battery, the subsequent regulation is solved by pulse limitation-current interruption. This happens at a frequency of units up to tens of Hz and for some controllers is indicated by a flashing LED labeled "charge" or "solar". The controllers are suitable for panels with the same system voltage as the battery voltage, otherwise there are losses when part of the power is wasted due to inappropriate V-A characteristics of the panel.
