Frequently Asked Questions
Can I use the RSDW20G-15 for a 15V automation or embedded load?
Yes, this model provides a constant 15V output rated for up to 1.33A and 20W. It is appropriate for 15V automation, embedded, or industrial electronics that require a regulated 15V supply within those limits.
Is the RSDW20G-15 suitable for systems that need 15V from an 18-75VAC source?
Yes, that is the intended conversion range for this unit. It accepts 18-75VAC input and converts it to a constant 15V output, making it suitable for equipment designed around that input window and a 15V rail.
Can this converter be used in railway-related 15V electronics?
Yes, the listed features include compliance with EN50155 and EN45545 railway standards, which is relevant for rail and transit electronics. Its 4000VDC isolation and -40°C to +85°C operating temperature also support use in demanding electrical environments.
Is the RSDW20G-15 appropriate for low-profile industrial assemblies?
It can be, because the converter uses a 1U low-profile, half-encapsulated design and measures 50.8 × 25.4 × 10.2 mm. Those mechanical specs help when integrating isolated 15V power into compact control or embedded hardware.
How does the RSDW20G-15 differ from the other RSDW20G output options?
All listed RSDW20G models share the same 20W power class, but their outputs are different. The RSDW20G-03 is 3.3V at 5.5A, the RSDW20G-05 is 5V at 4A, the RSDW20G-12 is 12V at 1.67A, and the RSDW20G-15 is 15V at 1.33A.
Is the RSDW20G-15 rated for outdoor conditions or only for temperature extremes?
The provided specifications define an operating temperature range of -40°C to +85°C. They do not include an IP rating, so moisture and dust protection for exposed outdoor use are not specified here.
