By: Frank Chen / Product Manager

MEAN WELL is the global standard power supply leader, marketing its own MEAN WELL brand in over 80 countries worldwide. In the security and fire alarm industry, MEAN WELL has three complete product lines, PCB type, DIN rail type and enclosed type, which include the PSC, DRC, DRS, SCP and AD series that cover from 35W~480W. In recent years, due to the needs created by rapid urban development, the demand for safe, reliable, certified and smart security/ fire alarm power supplies has been increasing. Accordingly, MEAN WELL is announcing its new Enclosed Type Economical Security/ Fire Alarm Power Supply LAD-120/ 240/ 360/ 600 series.

The LAD series is designed with 1U thin enclosed design, and is separated into the basic model (LAD-120/ 240/ 360/ 600) and UART communication model (LAD-360/ 600xU). The CH1 of both models can be used to supply power to the loads, and the built-in auxiliary output CH2 for both models can charge the battery, with the battery providing a UPS function. The CH1 output voltage can be adjusted from -20~+5%, and can fulfill all needs for different battery types and fine voltage adjustments. Complete protections (Short circuit/ OLP/ OVP/ OTP/ BAT, UVP/ BAT, Reverse polarity) are provided, and include complete safety approvals (CB/ UL/ RCM/ CE/ UKCA/ EAC) as well as design in line with GB17945 and GB4717 (UART version only) fire regulations. The LAD series is suitable for security control, fire protection, emergency lighting, access control alarm, computer room and peripherals, central monitoring, and all other UPS system needs.
