Relec Electronics announces the Mornsun LS Series of high density, high efficiency, low-cost power supplies. The versatile, board-mount AC-DC converters can be used in industrial & commercial internet of things (IoT) applications.

Power specialist, Relec Electronics announces that Mornsun’s established LS Series of board mount AC-DC converters is now available in outputs up to 15W.

The high density, vertical single in-line package (SIP) mount devices are suitable for industrial and commercial IoT applications where PCB space is at a premium. 

Models in the LS Series start at 1W, with a footprint of 35 x 18 x 11mm and Mornsun has extended the series up to 15W with dimensions of 44.5 x 24 x 15mm. The flexible AC-DC converters can be placed either horizontally or vertically to optimise use of space in what are typically constrained applications.

The LS Series modules meet EN62368 and EN60335 safety approvals, enabling them to be used in industrial designs and home appliances, respectively to create cost-effective designs, with the minimum of design effort. There is also a range of peripheral circuits and application notes to support engineers designing power for even the most challenging applications.

All variants cover 85 - 264Vac, with options to 305Vac and 528V ac, and wide dc input ranges of 120 - 430Vdc or 100 - 745Vdc, respectively. They operate across the -40 to +85°C temperature range.

The LS Series also has output short circuit protection, over-current protection and output over-voltage protection to ensure reliable operation in a wide selection of applications, from telemetry, robotics and instrumentation to household appliances and white goods, smart home networks, lighting systems in the home and agricultural monitoring and watering systems.

Relec’s engineers can arrange samples and discuss any peripheral components that may be required. Mornsun’s LS series are available to sample from stock at Relec Electronics and with production pricing and lead-times making them ideal for almost any project.
