LES SERIES - 15 WATT
DESCRIPTION
FEATURES
LES DC/DC converters provide up to 15 Watts of output
• Industry Standard Package • 24V and 48V Inputs
power in an industry standard package and footprint. With a • Industry Standard Pinout
maximum case temperature of 100°C, the LES is well suited • 85°C Case Operation
for the most demanding telecom, networking, and industrial • Short Circuit Protection
applications. The LES features 1500 VDC isolation, short
• Input Pi Filter and
6-Sided Shielding
• Regulated Outputs
• 1500V Isolation
circuit, and overtemperature protection, as well as six-sided
shielding. The LES is available with optional enable and
voltage trim. Please see the IAD series for dual-output
applications.
