LAD 120W-600W Security/Fire Alarm Power Supplies

MEAN WELL LAD 120W-600W Security/Fire Alarm Power Supplies are enclosed-type, cost-effective power supplies with 120W, 240W, 360W, and 600W versions. The series includes basic (LAD-120, LAD-240, LAD-360, and LAD-600) and UART communication (LAD-360xU and LAD-600xU) versions. MEAN WELL LAD Power Supplies are designed with a 1U thin enclosed design. Channel 1 of the basic and UART versions can be used to supply power to the loads. The built-in auxiliary output Channel 2 of both versions can charge the battery, with the battery providing an uninterruptible power supply (UPS) function. Channel 1 output voltage can be adjusted from -20% to +5%, and can fulfill all needs for different battery types and fine voltage adjustments. These power supplies include complete protections and safety approvals and can be used for security control, fire protection, emergency lighting, and more.
