Wide input AC/DC power supplies for embedded applications

22-09-2021 | XP | Power

XP Power has introduced the LCW series of regulated output cased AC/DC power supplies ideal for embedded industrial electronics, technology and equipment needing household approvals. The nine new series (LCW15, LCW25, LCW35, LCW50, LCW75, LCW100, LCW150, LCW200 and LCW320) provide power levels from 15W to 320W. All models meet EN 55032 Class B conducted and radiated emissions for simple and low-cost integration and offer an integrated connector cover to improve safety once installed.

The input voltage range of the series is from 85VAC to 305VAC, meeting global regulatory demands, suiting nominal inputs from 100VAC to 277VAC, with the 150W, 200W and 320W models featuring active PFC. Applications cover auxiliary power sources, security installations, smart home or office systems, lighting control, and ticketing and vending machines.

Depending on power level, the series is offered with nominal outputs ranging from 3.3V to 48V. To accommodate non-standard voltage applications, all models are user-adjustable by ±10% without exceeding the output voltage rating.

Provided with an extensive operating temperature range of -30C to +70C, the series gives full rated power to +50C, derating linearly to 60% up to +70C. The series is convection cooled up to 200W with the higher power LCW320 series providing an integrated temperature-controlled cooling fan, decreasing acoustic noise.

The low profile and compact footprint of the units further eases integration into the end application. Standard features in the series incorporate a low standby power consumption of less than 0.3W and output short circuit protection, as well as over-current and over-voltage protection. Furthermore, the LCW320 series offers a power ‘ON’ LED. As an option, conformally coated versions are provided.

Input to output isolation is 4,000VAC, input to ground isolation is 2,000VAC, and output to ground isolation is 500VAC. All models are safety certified to UL/EN 62368-1 with models in the LCW35/50/75/100/150 series also certified to EN 60335 for home automation and applications needing household or domestic approval. The operating altitude is up to 5,000m, which strengthens its global use.
