Frequently Asked Questions
Can I use the RSDW20H-12 for 12V industrial controllers or relay modules?
Yes, if the load needs a regulated 12V output and stays within 1.67A and 20W. This model is a constant-voltage 12V converter with a 43-160VAC input range for systems operating inside that specified input window.
Is this a good fit for 12V automation sensors, HMIs, or panel devices?
It is suited to 12V automation devices that require up to 1.67A, with total load power not exceeding 20W. The compact 50.8 × 25.4 × 10.2 mm size and 1U low-profile form can also help where panel space is limited.
Can the RSDW20H-12 be used in railway or transit electronics that need 12V power?
It can be considered for 12V railway or transit electronics when the load is within 1.67A and 20W. The stated features include compliance with EN50155 and EN45545 railway standards and 4000VDC isolation.
Is this converter meant for indoor use only, or can it handle wider temperature swings?
The specified operating temperature range is -40°C to +85°C, so it can handle broad temperature variation within those limits. No IP rating is provided, so exposed outdoor use should rely on a suitable enclosure rather than the converter alone.
What is the difference between the RSDW20H-12 and the other models in the same series?
The RSDW20H-05, RSDW20H-12, and RSDW20H-15 all share 20W power, 43-160VAC input, 50.8 × 25.4 × 10.2 mm dimensions, 0.035 kg weight, and -40°C to +85°C operation. Their outputs differ: 5V at 4A for the -05, 12V at 1.67A for the -12, and 15V at 1.33A for the -15.
