DESCRIPTION
LCD10 DC/DC converters provide up to 10 watts of output power in an industry standard
package and footprint. These units are specifically designed to meet the power needs of low
profile. All models feature with 2:1 wide input voltage of 9~18 VDC, 18~36 VDC and 36~75VDC,
comprehensively protected against over-current, over-voltage and input under-voltage protection
conditions, and trimmable output voltage. The converter can meet EN55022 Class B with an
external capacitor only.
