产品详情

welding machine capacitor: dmj-mc series

introduction:

1.aluminum round shell encapsulation, sealed with dry resin;
2.
copper nut / screw leads, insulated plastic cover positioning, easy installation;

3. large capacity, small size;

4. resistance to high voltage, with self-healing;

5. high ripple current, high dv / dt withstand capability.

application

1. widely used in dc-link circuit for filtering energy storage;

2. can replace electrolytic capacitors, better performance and longer life;

3. wind power, photovoltaic power inverter,electric vehicles and hybrid vehicles;power suppliers svg, and induction heating equipment, for the dc link filter.
