400W isolated DC-DC converter Wide input and regulated single output
Descriptions
VCF48_QBO-40W(F/H)R3 series is a high-performance product designed
for the field of communication powers up.The DC-DC converters
feature 40W output power with no requirement for minimum load, wide
input voltage from 36-75VDC, and allowing operating temperature as
hige as 85C. Addtional product features include input under-voltage
protection, output over-voltage, over-current,
short-circuitandover-temperature protection,remote On/Off
control,remote sense compensation,output voltage trim
adjustment.The products meet CLASB of CISPR32/EN5032 standards by
ading there commended external components,and they are widely used
in applications such as battery power suplies, industrial
control,electricity,instruments,communication and inteligent
robotic.

Note: ①Use“F”suffix is for added aluminum baseplate and“H”suffix for heat sink mounting. We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements; ②Exceeding the maximum input voltage may cause permanent damage; ③In order to ensure the output stability, a minimum capacitive load must be connected to the output side of the product. | ||||||||
