Mean Well - DRS-480

The Mean Well DRS-480 series is a compact backup power supply line built for installers who need dependable performance without complicated setup. Designed for critical electrical and plumbing control systems, this series keeps your equipment running when the main power fails. You get two straightforward options: the Backup Power Supply 480W 24V 20A DRS-480-24 delivers 24 volts at 20 amps, while the Backup Power Supply 480W 48V 10A DRS-480-48 provides 48 volts at 10 amps. Both models are engineered to work seamlessly with standard control panels, access readers, and pump controllers.

Reliable Power When You Need It Most

Power outages can shut down security gates, fire alarms, and water circulation pumps in seconds. The DRS-480 series solves this by automatically switching to backup power the moment the main supply drops. There is no delay and no manual reset required. The 24V 20A model handles heavier loads like motor starters and multiple sensors, while the 48V 10A version is ideal for longer cable runs and low-current control circuits. You can trust these units to hold voltage steady and protect sensitive electronics from sudden drops.

Built for Fast, Clean Installations

Installers appreciate gear that fits standard racks and DIN rails without extra adapters. The DRS-480 series mounts quickly on standard 35mm DIN rails, saving you time on every job. Clear terminal markings and screw-type connections make wiring straightforward, even in tight electrical panels. The compact footprint leaves room for other components, and the open design allows for natural airflow, so you do not need extra cooling fans. Everything you need is right there on the unit, reducing guesswork on site.

Simple Maintenance and Long-Term Use

Keeping backup systems running smoothly should not require a specialist. The DRS-480 series uses high-quality capacitors and robust switching components that resist heat and voltage spikes. Status LEDs give you a quick visual check on input power, battery connection, and output status, so troubleshooting takes minutes instead of hours. The units are built to handle daily cycling between main power and backup mode without wear. This means fewer service calls and happier end users who know their systems stay online.

Why Installers Choose the DRS-480 Series

Mean Well has earned a strong reputation for delivering industrial-grade power supplies at practical prices. The DRS-480 series continues that tradition by combining proven reliability with installer-friendly features. Whether you are wiring a new plumbing control room or upgrading an existing security panel, these power supplies give you the confidence to finish the job right the first time. Stock them in your van, mount them in the panel, and let the system run without interruption.
