Core advantages of ER transformer
1. The round core magnetic core has smooth winding, high window utilization rate, and excellent leakage flux control performance.
2. Plastic housing packaging, the magnetic core is protected by the housing, resistant to shock and drop, suitable for the environment of large vibrations of the entire machine, fixed with steel clips.
3. Dual-slot frame structure: Primary and secondary are physically isolated, the creepage distance is easier to meet safety standards, and the distributed capacitance is lower.
4. High customization freedom: Pins, turns ratio, inductance, withstand voltage, and the number of windings can all be designed as needed.
5. Strong reliability: The magnetic core is not prone to loosening, reducing the risk of working squeaking, suitable for industrial and energy storage long-term operation equipment.

Q: How is the magnetic core of ER4215 fixed?
A: The locking magnetic core is wrapped with a special plastic shell, which is different from the metal steel clamp locking method. This design offers better vibration resistance performance.
Q: What are the advantages of the ER4215 round core magnetic core?
A: The circular central column winding is smoother, and the bending stress of the wire is smaller. The window utilization rate is high, which is beneficial for reducing leakage inductance and distributed capacitance, and improving power supply efficiency.
Q: Can ER4215 be used as multiple auxiliary windings?
A: Yes, it supports the main power winding + multiple auxiliary windings. The turns ratio, inductance, output voltage, and pin layout can all be customized.
Q: What are the advantages of the ER4215 dual-slot frame compared to the single-slot frame?
A: For primary-secondary physical isolation, the creepage distance can be more easily met the standards, reducing the distributed capacitance between windings, and being more favorable for EMI performance of LLC and resonant power supplies.
