The ERG DMF63232F (DMF SeriesDMF Series
DMF SeriesDMF Series
DMF Series) DC to AC inverter
features onboard connectors and can be easily dimmed
using an external pulse-width modulated control signal or
using the onboard PWM with an external analog voltage.
This unit is less than 9mm in height and the six mounting
holes makes installation very straight forward.
Powered by a regulated +12 Volt DC source, the
DMF63232F is designed to power the 6-lamp backlights
of the NEC NL204153BC21-01, NL204153BC21-01A and
NL204153BC21-02 displays, with onboard PWM.

(Note 1) Surface temperature must not exceed 80 degrees C; thermal management actions may be required.
(Note 2) Input current in excess of maximum may indicate a load/inverter mismatch condition, which can result in
reduced reliability. Please contact ERG technical support.
(Note 3) Provided data is not tested but guaranteed by design.
Application Notes:
1) The minimum distance from high voltage areas of the inverter to any conductive material should be .12
inches per kilovolt of starting voltage.
2) Mounting hardware to be non-conductive.
3) Open framed inverters should not be used in applications at altitudes over 10,000 feet.
4) ACreturn should be left floating, not grounded.
5) Contact ERG for possible exceptions.
Specifications subject to change without notice.
