Product overview

RM9001C uses adaptive LED four segment driver mechanism, can be flexible to set up LED string, adapt to different market power voltage, thereby improving the utilization of LED and total output lumens. RM9001X integrated 700V high voltage MOS tube makes surge resistant design easier. RM9001C with adjustable temperature control function. Can be set according to different application of different temperature control node.

Functional characteristics

1, very low THD and high PF value;

2, adjustable over temperature control function;

3, multi chip parallel application;

4, the four paragraph LED lamp string can be configured flexibly;

5, LED current can be set externally;

6, the external circuit is simple, no electrolytic capacitors and magnetic components.

application area

The utility model is used for high power lamps, such as ceiling lamps, industrial and mining lamps, projection lamps, etc.
