Frequently Asked Questions
Can I use the WDR-120-12 in a 12V PLC control cabinet?
Yes, this model is suited to 12V industrial control panels and PLC cabinets that need a 12V DC supply up to 10A. Its DIN rail form factor and 40.0 mm slim width help it fit into space-constrained control enclosures.
Is this a good choice for 12V industrial automation devices in a DIN rail panel?
It is appropriate for 12V industrial automation equipment when the total load stays within 120W and 10A. The wide 180-550VAC input also makes it suitable for panels using 1 phase or 2 phase input power.
Can this power a 12V building management or control panel assembly?
Yes, it can be used in 12V building management and control cabinet applications where the connected devices require 12V DC and the combined demand does not exceed 120W. The metal case and DIN rail design are aligned with enclosed industrial panel use.
Is the WDR-120-12 meant for open-air use or for control cabinets?
This unit is better suited to indoor control cabinets and electrical enclosures rather than exposed locations. The provided specs list a metal case, DIN rail format, and an operating range of -25°C to +70°C, but no outdoor IP rating is provided.
How does the WDR-120-12 compare with other WDR series models?
Within the series, the closest same-power siblings are WDR-120-24 at 120W, 24V, 5A and WDR-120-48 at 120W, 48V, 2.5A. Higher-power options 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-power options 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.
