35W to 350W AC-DC power supplies improve reliability in industrial applications
XP Power announces the introduction of the LBA series of low-profile enclosed, chassis-mount, single-output AC-DC power supplies, covering power levels from 35W to 350W. Designed for cost-sensitive industrial technology applications, the series provides a versatile, reliable, and easy-to-integrate platform for engineers developing industrial automation, security and surveillance systems, lighting control, smart home and building control equipment.
The LBA series combines compact form factors with robust performance, offering regulated single output voltages from 5V to 48VDC (model dependent) with output adjustment capability to compensate for system tolerances or voltage drops. This output voltage trim allows engineers to ensure accurate voltage delivery at the point of load and improve overall system performance and reliability. A universal 90 to 264VAC input range and active PFC support efficient and flexible operation across global applications.
With efficiency of up to 90%, the series minimises heat generation and enhances overall system reliability. In lower power ratings, the LBA series offers a compact footprint of just 99 x 82 x 30 mm (35W and 50W models) and 99 x 97 x 30 mm (75W), smaller than many alternatives at this power level and ideal for space-constrained designs. Models up to 200W feature convection-cooled, fanless operation, designed for noise-sensitive environments. The 350W variant incorporates fan cooling to support increased power density. A wide operating temperature range of -30°C to +70°C ensures reliable performance in harsh environments.
A key advantage of the LBA series is its enclosed, chassis-mount design, providing enhanced robustness and protection against dust and accidental contact in demanding industrial environments. Worldwide ITE safety approvals simplify system certification. Class I construction with protective earth provides a defined grounding path, supporting compliance with end equipment safety requirements and enhancing operator protection in industrial environments. Class B conducted and radiated emissions help eliminate the need for external EMC filtering, reducing system complexity and cost.
Additional features further simplify integration and operation. The integrated screw terminal block connector cover improves safety and installation ease, while selected models include remote ON/OFF functionality for greater system control. A power ON LED indicator provides immediate visual confirmation of status, supporting fast installation and troubleshooting. Comprehensive protection features, including short circuit, overvoltage, and overload protection, enhance system reliability.
The LBA series is available from Avnet Abacus, DigiKey, Distrelec, element14, Farnell, Mouser, RS, TME, approved regional distributors, or direct from XP Power with a 3-year warranty.
