Frequently Asked Questions
Can I use the RSDW10H-03 for a 3.3V embedded processor, FPGA, or logic rail?
Yes, it is a constant-voltage converter with a 3.3V output rated at 2.5A and 10W. That aligns with applications that need a regulated 3.3V rail within those output limits.
Is the RSDW10H-03 suitable for industrial or rail electronics running from a higher input range?
It is built for a 43-160VAC input range and provides 3.3V output on the secondary side. The listed EN50155 and EN45545 compliance also makes it relevant for railway-related electronic subsystems.
Would this model work for compact automation or communications boards that need isolated 3.3V power?
Yes, the converter provides 4000VDC isolation in a 31.8 x 20.3 x 10.2 mm package. Its 1U low-profile, half-encapsulated construction supports dense board-level or enclosure-level designs.
Can the RSDW10H-03 handle wide ambient temperatures, and is it rated for outdoor exposure?
Its operating range is -40°C to +85°C, so it is specified for broad temperature conditions. No IP rating is listed, so the provided data does not establish exposed outdoor or sealed-enclosure performance.
What changes across the RSDW10H series besides the part number?
The RSDW10H siblings share the same 10W platform but have different outputs. RSDW10H-03 is 3.3V at 2.5A, RSDW10H-05 is 5V at 2A, RSDW10H-12 is 12V at 835A, and RSDW10H-15 is 15V at 666A.
