Enclosed single-output PSUs for industrial equipment

September 14, 2015 // By Graham Prophet
Artesyn Embedded Technologies’ LCB family of enclosed AC-DC power supplies comprises 23 models designed to be a low cost solution for general-purpose industrial applications requiring a single low voltage DC supply. Efficiency is typically 89/90% and no-load power consumption is 0.5W.

Four series have nominal power output ratings of 35, 50, 100 and 150W. The LCB35, LCB50 and LCB100 series each comprises six single-output models, offering voltages of 3.3V, 5V, 12V, 15V, 24V and 48V, while the LCB150 series comprises five single-output models, offering voltages of 5V, 12V, 15V, 24V and 48V. LCB35, LCB50 and LCB100 series units accept a universal 88–264 Vac input and are also capable of operating from a 125–373 Vdc input, while the each LCB150 model accepts an 88–132 Vac or 176–264 Vac input and is also capable of operating from a 248–373 Vdc input.

Designed for normal convection cooling, all LCB family power supplies accommodate an ambient operating temperature range of -25 to 70C, with linear derating above 50C. An externally accessible trim allows the output voltage to be adjusted by ±10%. The supplies carry UL/TUV 60950-1 safety approvals and have calculated MTBFs ranging from 200,000 to 460,000 hours.
