DESCRIPTION
Industry Control System
Measurement Equipment
Semiconductor Equipment
LED15W single output DC/DC converters provide up to 15 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 18-75 VDC, comprehensively protected against
over-current, over-voltage and input under-voltage protection conditions, and
trimmable output voltage.
