FAQ
What does the Mean Well DET01L-12 do?
The DET01L-12 is a 1W DC-DC converter designed to convert a 5V DC input to a ±12V dual DC output. It is intended for low-power DC power conversion in compact electronic equipment.
What are the main electrical specifications of the DET01L-12?
This model is rated for 1W output power and provides a ±12V dual DC output. Its rated output current is ±42mA, and it operates from a 5V nominal DC input (4.5–5.5V range).
Is the DET01L-12 suitable for electrically isolated applications?
Yes. The DET01L-12 provides 3000VDC input-to-output isolation, which can be important in designs that require separation between input and output circuits. That makes it a stronger choice than non-isolated DC-DC converters for applications where isolation is required.
What protection and reliability features are included in this converter?
The DET01L-12 includes momentary short-circuit and overload protection; sustained faults can damage the unit, so an input fuse is recommended. It is built using internal SMD technology, undergoes a 100% full-load burn-in test, and is described as a low-cost, high-reliability model.
What operating temperature range does the DET01L-12 support?
This model is specified for operation from -40°C to 85°C, with output derating at higher temperatures according to the datasheet's derating curve. That wide temperature range makes it suitable for demanding industrial or embedded environments where ambient conditions can vary significantly.
What approvals and warranty does the Mean Well DET01L-12 have?
The DET01L-12 is approved to UL and CUL standards. It also includes a 1-year warranty from the manufacturer.
