Details
Meanwell ENC-240-48 is single output 240W AC/DC desktop type charger with 57.6V55.2V36-60V4A230.4W15-45AH<1mA. The item is equipped with 3 stage charging curve, and accepts 90~264VAC input. Meanwhile, it provides built-in active power factor correction (PFC) function, 7" standard width, and complete safety certification (UL/CUL/CB/CE/FCC). In addition to the embedded pre-defined charging curves, the default curve is programmable, and therefore able to accommodate different types of batteries such as lead- acid batteries (gel, flooded and AGM) and li-ion batteries (lithium iron and lithium manganese). The design is specially controlled by MCU, permitting users to adjust the appropriate charging methods and parameters for different battery specifications. Furthermore, ENC-240-48 could work for the ambient temperature range -30℃~+70℃ under free air convection. it is also supplied with various protections such as Short circuit, Over voltage, Over temperature, Battery under voltage, Battery over voltage and Battery reverse polarity protection. In light of its longevity, good quality, and high reliability, Meanwell ENC-240-48 is very suitable for radio system backup program, land radio system, monitoring system electric and bicycle charger and other applications
