Módulo de búfer de carril DIN original Mean Well DBUF40-24 24 V 40 A, respaldo de condensador sin mantenimiento para fuente de alimentación industrial (DBUF40-24)

Descripción

Overview MEAN WELL DBUF Series - 24V DIN Rail Buffer Module for Short-Term Power Failure BridgingThe DBUF20-24 and DBUF40-24 buffer modules from MEAN WELL are supplementary devices designed to work alongside 24V DC regulated power supplies. In the event of momentary mains failure, voltage sag, or power interruption, these modules instantly provide stable power to the load, bridging the gap until input power recovers. Buffer Mode Selectable via DIP Switch:Fixed Mode (22Vdc): Output stabilizes at 22Vdc when bufferingDynamic Mode (Vin-1Vdc): Output maintains input voltage minus 1V Why choose DBUF Series over traditional battery-based UPS?Maintenance-Free: Utilizes long-life electrolytic capacitors instead of lead-acid batteries. No battery replacement, no recycling costs, and a significantly longer operational lifespanInstant Response: No switching delay—full power is available immediately during a power disturbanceSpace-Saving DIN Rail Design: Slim form factor (63mm width) allows seamless integration into existing control cabinets without requiring bulky battery packs.

Características

• Tecnología de respaldo de capacitores sin mantenimiento: a diferencia de los sistemas UPS tradicionales que requieren reemplazo de baterías de plomo-ácido, la serie DBUF utiliza capacitores electrolíticos de larga duración para almacenamiento de energía. Esto elimina los costos de mantenimiento de la batería, ofrece una respuesta ultrarrápida sin demora de conmutación y garantiza un rendimiento confiable incluso en entornos con frecuentes perturbaciones eléctricas.
• Reliable Short-Term Hold-Up Protection: Provides stable 24V output during momentary power interruptions or voltage sags. DBUF20-24 delivers 350ms hold-up time at 20A full load, while DBUF40-24 delivers 250ms at 40A full load. Under light loads (as low as 0.1A), hold-up time extends up to 62 seconds. Prevents PLCs, industrial PCs, and sensitive equipment from unexpected shutdown or data loss.
• Space-Saving DIN Rail Mounting & Parallel Expansion: Standard TS35/7.5 or TS35/15 DIN rail mounting with a compact footprint (63 x 125.2 x 114.9mm). Supports parallel connection of multiple DBUF modules to proportionally extend hold-up time or increase output capacity, offering flexible scalability for different system requirements without redesigning your power architecture.
• Dual Buffer Modes & Smart Status Monitoring:Selectable buffer modes via DIP switch: Fixed Mode (22Vdc) or Dynamic Mode (Vin-1Vdc) to match various load characteristics. Features LED status indicators (Ready / Charging / Buffering), plus remote control (Inhibit) and signal outputs (Ready / Buffering) for easy integration into automated control systems.
• Wide Temperature Range & Comprehensive Protection:Operates reliably in harsh environments from -25°C to +75°C. Built-in full protections: short circuit, overload, over-voltage, and reverse polarity (no damage). Certified with CB / UL / CUL / EAC / CE, backed by MEAN WELL's 3-year warranty – ideal for industrial automation, security surveillance, telecom, and medical equipment.
