Product Details
The R-78HE-5.0-0.3 is a low cost switching regulator module in a compact package that has been specially designed for battery-powered use, but will find many other high input voltage applications. The exceptionally wide input voltage and operating temperature range, high MTBF (15 mio. hrs), tight regulation and low quiescent current consumption makes this converter ideal for 36V/48V lithium-ion and 12V/24V/48V lead-acid battery-powered applications. The 100V surge withstand capability means that external voltage clamping circuits can be eliminated.
Designed for 12V - 60V battery-powered apps
