Snaptec has released a new DC/DC converter range called GB3 series.
The GB3 is a 300W highly integrated DC/DC converter designed for heavy duty industrial and mobile applications.
The input stage of these converters is designed in accordance to ISO7637 and SAE J1113; with wide input window, additional surge protections, as well as EMC harden.
Different output voltages are available. The full encapsulation of these converters provides ideal moisture and shock protection.
The GB3 series also uses a patented startup circuitry to enhance startup of high surge load.
The converter is encapsulated into an aluminium U-channel as the heatsink surface for the converter.
Utilising the new planar magnetic and high integration ceramic technology; the unit footprint measures only 90x180mm, with the total height of 95mm. Input and output to the unit is via 5mm pluggable screw-lock terminal blocks.
A green LED indicates the presence of output voltage. Output voltage is factory set to the initial accuracy of 0.5%.
Maximum operating ambient temperature of the unit is 60°C without derating. The maximum surface temperature rise of the heatsink would be around 40°C above ambient.
(Direct skin contact with the heatsink surface should be avoided.) The module has an internal shunting device for input surge and reverse polarity protection.
In order for these protections to function correctly and also to avoid fire risk, the unit must be connected with an external fuse.
Various input ranges from 9V up to 120VDC and output voltages of from 5V to 60VDC are available. Custom designs are also possible.
The GB3 represents a breakthrough in high power density and robust design and is ideal for high vibration, high temperature applications.
