Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 400VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
6. Derating may be needed under low input voltage. Please check the derating curve for more details.

FAQ

Can I use the WDR-480-48 for a 48V industrial control cabinet?

Yes, this unit is designed for DIN rail industrial power distribution where 48V DC is required inside a panel or enclosure. It provides 480W at 48V with 10A output current for higher-capacity 48V control loads.

Is the WDR-480-48 suitable for building automation panels that use 48V DC equipment?

It can be used for building automation or control systems that operate on 48V DC and fit within 480W and 10A. The slim metal housing and DIN rail form factor are intended for organized cabinet integration.

Can this model support multiple 48V devices in an industrial automation enclosure?

Yes, it is a higher-capacity WDR option for 48V DC systems, with 480W total output and 10A available current. That makes it appropriate when one DIN rail supply must support several 48V panel loads within those limits.

Is the WDR-480-48 appropriate for enclosed control cabinets in demanding temperature conditions?

It is intended for control cabinets and enclosures rather than exposed locations. The operating temperature range is -30°C to +70°C, and the metal-case DIN rail design aligns with enclosed industrial installations.

How does the WDR-480-48 compare with other models in the WDR family?

Among 48V versions, the WDR family includes WDR-60-48 at 60W, 1.25A; WDR-120-48 at 120W, 2.5A; WDR-240-48 at 240W, 5A; and WDR-480-48 at 480W, 10A. Other siblings are WDR-60-5 at 50W, 5V, 10A; WDR-60-12 at 60W, 12V, 5A; WDR-60-24 at 60W, 24V, 2.5A; WDR-120-12 at 120W, 12V, 10A; WDR-120-24 at 120W, 24V, 5A; WDR-240-24 at 240W, 24V, 10A; and WDR-480-24 at 480W, 24V, 20A.
