/ Product Characteristics /
1. This product adopts high-quality stainless steel as the support, and high-quality insulation material as the lining plate is firm and durable.
2. After resistance combination, the power can be made into 3X200W and 3X450W.
3. Resistance welding process is adopted between the leading end and the resistance body. There is no contact resistance and cracking is not easy when the current is too strong.
4. Continuous surface temperature rise does not exceed 350°C.
5. Modular assembly, can be required series, parallel, to meet the voltage current and other parameters of the requirements, easy replacement
6. This product is widely used in photovoltaic grid-connected inverter equipment.
