Product Characteristics

Intelligent    Safe  Efficient

 ● High Power Factor: (APFC) Active power factor correction is used in AC input.    The power factor is bigger than 0.98 to achieve green grid.

● High Efficiency: LLC resonant soft-switching technology is used in the charger to achieve the efficiency of 94.0% at full load. It produces little heat and has high reliability.

● Wide voltage input range: 90VAC-264VAC and meets the net grid need of    home and abroad

● Convenient installation: Fan-cooling, sealed and  water proof structure.Temperature rise is lower than natural coolling and the charger is reliable.

● It charges lead-acid batteries intelligently. Microprocessors are built in the  chargers. They judge the battery relative capacity and identify the ambient  temperature in charging process. There will be corresponding charging curves according to the relative capacity of the battery and ambient temperature. The constant current will control in the whole charging proces. It does good to the  balance of batteries and extends the battery life.

Size and weight

Net weight:6.0 kg

Temperature

Operating Temperature: -30 ℃ -55 ℃
Storage Temperature: -40 ℃ -80 ℃

Protection Functions

●Overheat protection: when the internal temperature inside the charger exceeds 80 ℃, the charging current automatically reduces. When it is over 87 ℃, the charger shuts down for protection. When the temperature falls, the charger automatically resumes to charge.
