Frequently Asked Questions
Can I use the RD-125-1248 for a compact 12V industrial controller that also needs a second output?
Yes, this is a 125W enclosed AC-DC power supply with dual output and a listed 12V output rated at 2.3A. Its 199.0 × 98.0 × 38.0 mm form factor suits tighter control boxes where space is limited. The 88-132VAC input range defines the AC source window for this model.
Is the RD-125-1248 a fit for embedded systems or instrumentation built around a 12V rail?
It can be used where the design calls for a 12V output at 2.3A within a 125W enclosed supply platform. The dual output design can also be relevant when the equipment needs more than one DC rail from one power supply. Its miniature size and 0.7 kg weight support use in smaller enclosures.
Can this model support light-duty automation panels in environments with vibration?
The feature set states it withstands 5G vibration and operates up to +70°C, which makes it more suitable for equipment environments than a basic office-only supply. The listed 12V output is 2.3A, so it is aimed at lighter 12V loads than the 3.7A RD-125-1224. Total rated power is 125W.
Is the RD-125-1248 suitable for outdoor applications?
The published operating temperature range is -25°C to +70°C, so the model is specified for a broad indoor operating range. No IP rating is listed in the provided specs, which means the outdoor ingress-protection level is not established here. The environmental data provided is the temperature range plus 5G vibration resistance.
How does the RD-125-1248 compare with nearby RD series options?
Compared with the other 125W entries listed here, RD-125-1224 is 125W 12V 3.7A, this RD-125-1248 is 125W 12V 2.3A, and RD-125-2448 is 125W 24V 2A. Other provided RD siblings include RD-125A at 130.9W 5V 7.7A, RD-125B at 133.4W 5V 4.6A, RD-3513 at 35.1W 13.5V 1.3A, RD-35A at 32W 5V 4A, RD-35B at 35W 5V 2.2A, RD-50A at 54W 5V 6A, RD-50B at 53.6W 5V 4A, RD-65A at 66W 5V 6A, RD-65B at 68W 5V 4A, and RD-85A and RD-85B at 88W 5V 8A. RD-125-2412, RD-125-4812, RD-125-4824, RD-125A-OB, RD-125NB, and RD-65A-OB are listed without full specs in the provided data.
