SD-25 series is a DC-to-DC switching power supply that uses copper coil transformers.
Each installation is safe and the power supply driver is designed with strong filter magnetic ring capacitors.
The power is larger, so the SD-15 is perfect for applications that require more power.
The white cap on the connector is for safety precautions against electric shock and dust protection
And we make transformers and power inductors with pure coppers all by ourselves,
Weho stocks 150,000 sets of commonly used models, ensuring quick delivery.
Our products have CE ROHS certification to ensure quality.
This product is covered by a 24-month warranty.
