The ERG E2741 (E200II Series) dc to ac inverter is
specifically designed to power the Panasonic
EDTCB03Q2F LCD display module to a moderate
brightness level from a +12 volt dc source.
The E2741’s small size, 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 Panasonic
EDTCB03Q2F display. Custom units, providing
different inputs, outputs or package refinements are
available.
