Frequently Asked Questions
Can I use the RSDW20G-12 for 12V automation and control devices?
Yes, it delivers a constant 12V output rated at up to 1.67A, with 20W total output power. It is suitable for 12V automation, control, and embedded devices that stay within those output limits.
Is the RSDW20G-12 a fit for converting a wide industrial input range to 12V?
Yes, the converter accepts 18-75VAC input and provides a regulated 12V output. That makes it useful for industrial or embedded systems that need a 12V rail from a source within that input range.
Can this model be used in railway or transit electronics that require 12V power?
It is intended for rugged transport-related use because the features list compliance with EN50155 and EN45545 railway standards. The -40°C to +85°C operating temperature and 4000VDC isolation further support use in demanding electronic environments.
Is the RSDW20G-12 suitable for compact embedded equipment with limited mounting space?
Yes, the unit measures 50.8 × 25.4 × 10.2 mm and weighs 0.035 kg, which helps in compact enclosures. Its 1U low-profile, half-encapsulated construction is also relevant for dense industrial and embedded layouts.
What are the output differences between the RSDW20G-12 and its sibling models?
Each listed RSDW20G version is rated at 20W, but the voltage and current combinations 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.
Can the RSDW20G-12 be used where temperatures swing widely?
The specified operating range is -40°C to +85°C, so it is rated for very cold and hot conditions. No IP rating is included in the provided specifications, so ingress protection for outdoor exposure is not stated here.
