DESCRIPTION
APPLICATIONS
Wireless Network
Telecom/Datacom
LCD10W 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 4:1 ultra wide input voltage of 9~36 VDC and
18~75VDC, 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.
