The E1950 (E200II Series) dc to ac inverter is
specifically designed to power the Sharp LQ10D421
LCD display to a moderate brightness level from a
+12 volt dc source.
The E1950's small size and encapsulated package
makes it the ideal power source for applications where
small size, high efficiency and reliability are critical.
This inverter is designed to satisfy the most common
cold-cathode lighting requirements for the Sharp
LQ10D421 LCD display. Custom units, providing
different inputs, outputs or package refinements are
available.
