The LCW series of regulated output cased AC/DC power supplies are ideal for embedded industrial electronics, technology, and equipment requiring household approvals. They are in stock at Digi-Key.

The nine series (LCW15, LCW25, LCW35, LCW50, LCW75, LCW100, LCW150, LCW200, and LCW320) offer power levels of 15 W to 320 W.

These models meet EN 55032 Class B conducted and radiated emissions standards for easy and low-cost integration and feature an integrated connector cover to enhance safety once installed.

These devices offer an input voltage range of 85 V_AC to 305 V_AC, satisfying global regulatory requirements and suiting nominal inputs of 100 V_AC to 277 V_AC.

The 150 W, 200 W, and 320 W models feature active PFC.

Applications include auxiliary power sources, security installations, lighting controls, smart homes or office systems, and ticketing and vending machines.

Depending on the power level, the LCW series is available with nominal outputs ranging from 3.3 V to 55 V.

To accommodate non-standard voltage applications, the power supplies are user-adjustable by ±10% without exceeding the output voltage rating.

Offered with a wide operating temperature range of -30°C to +70°C, the power supplies deliver full-rated power of +50°C, derating linearly at 60% up to +70°C.

The LCW series are convection-cooled up to 200 W with the higher power LCW320 series featuring an integrated temperature-controlled cooling fan, reducing acoustic noise.

The low-profile and compact footprint eases integration into the end application. Standard features include a low standby power consumption of less than 0.3 W, output short-circuit protection, overcurrent protection, and overvoltage protection.

The LCW320 series features a power ‘ON’ LED.

As an option, conformally coated versions are available. Input to output isolation is 4,000 V_AC, input to ground isolation is 2,000 V_AC, and output to ground isolation is 500 V_AC.

All models are safety-certified to UL/EN 62368-1.

Models LCW35/50/75/100/150 are also certified to EN 60335 for home automation and applications requiring household or domestic approval.

The operating altitude is up to 5,000 m which strengthens its global use.
