Key Specifications

Instrument and apparatus requests the transformer is with high efficiency, small loss, Low interference resistance, small magnetic leakage, low temperature rise and high safety requirements. It is better to choose toroidal structure. The magnetic circuit closure is good for Toroidal transformer. It can take full advantage of the magnetic properties of silicon steel, reduce the magnetic leakage of the core.

Product Feature:
1. Pure copper coil
2. High permeability silicon steel
3. Full power design
4. The tranformer has wiring terminal at the end of lead wire, it is very easy to install.
5. Low magnetic leakage, low noise.
6. Has temperature protector to ensure the safe operation of the transformer.

Sample Lead Time： 3~5 days
Production Lead Time：3 Weeks (Urgent order can be negotiated)
Quantity：No MOQ Require
Production : 80k units per month
