Frequently Asked Questions
Can I use the WDR-120-48 in a 48V industrial control panel?
Yes, this unit is suitable for 48V control panels and industrial cabinets that need up to 120W at 48V DC. Its rated output is 2.5A, and the DIN rail body uses a 40.0 mm slim profile for compact enclosures.
Is this model suitable for 48V building automation or monitoring equipment?
It can be used for 48V building automation and monitoring equipment when the total demand remains within 120W and 2.5A. The wide 180-550VAC input range also supports use in panels fed from 1 phase or 2 phase input power.
Can the WDR-120-48 be used for 48V industrial automation devices on DIN rail?
Yes, it is intended for DIN rail industrial applications that require a 48V DC source and fit within its 2.5A output capacity. The metal case and slim housing are useful for organized control cabinet layouts.
Is this power supply intended for protected enclosures or exposed environments?
This model is better suited to control cabinets and other protected enclosures. The listed operating range is -25°C to +70°C, but no exposed-location or outdoor IP rating is provided in the specs.
How does the WDR-120-48 differ from the rest of the WDR family?
At 120W, the series offers WDR-120-12 at 12V, 10A, WDR-120-24 at 24V, 5A, and WDR-120-48 at 48V, 2.5A. Higher-capacity models are WDR-240-24 at 240W, 24V, 10A, WDR-240-48 at 240W, 48V, 5A, WDR-480-24 at 480W, 24V, 20A, and WDR-480-48 at 480W, 48V, 10A. Lower-capacity versions are WDR-60-12 at 60W, 12V, 5A, WDR-60-24 at 60W, 24V, 2.5A, WDR-60-48 at 60W, 48V, 1.25A, and WDR-60-5 at 50W, 5V, 10A.
