Grewin 220vac 230vac Custom Made Pcb Toroidal Transformer For Power Supply - China

We have passed ISO9001: 2015, CE, CB, SGS approval and IEC report Grewin 220VAC-230VAC Custom-Made PCB Toroidal Transformer for Power Supply GW-I Series: High Quality Encapsulated Toroidal Transformers with Pins

Grewin 220VAC-230VAC Custom-Made PCB Toroidal Transformer for Power Supply Grewin 220VAC-230VAC Custom-Made PCB Toroidal Transformer for Power Supply Remark:

A.

D refers to the volume of a corresponding transformer, which will be replaced with a digit.

For the transformer with a single winding, the corresponding max.

volume can be reached; for the transformer with two or more windings, the corresponding volume will be reduced properly.

B.

Being a tendency of future pin transformer, it is applide with our best self-made toroidal core (Po≤0.9W/Kg) in the result of High Efficiency, Low Power Loss and Low Temperature-rise to be Green, Energy-saving & Environment-friendly.

C.

Attributed to our Patent Technology, excluding the pins distribution mentioned above, the pins distribution can be freely adjusted by following customer's advice.

D.

Nice Appearance, Small Size, Moisture Proof & Mould Prevention.

E.

Pins Quantity can be reduced or increased based on your requirement.
