Supplier's note

1. Technical Breakthroughs:

   • Pro Model’s 1600V Reverse Voltage: Exceeds industry standards by 25%, enabling safer operation in high-stress environments.
   • Enhanced Thermal Design: The Pro Model’s 1.5°C/W thermal resistance reduces heat buildup by 40%, extending lifespan in continuous-use scenarios.
   • Compact Bolted Housing: All models feature rugged metal construction, ensuring durability in vibration-prone industrial settings.

2. Version Selection Guide:

   • Base Model (ZPQ20A): Ideal for small workshops or light-duty welding (e.g., hobbyist use). Its compact size and cost-effectiveness make it a go-to for low-power applications.
   • Advanced Model (ZPQ40A): Perfect for medium-scale fabrication shops requiring reliable performance without excessive thermal management.
   • Pro Model (ZPQ100A): Designed for industrial heavy-duty welding systems, where high current and voltage stability are critical. Its tripled current capacity compared to the Base Model ensures seamless operation in demanding environments.

With the ZPQ100A’s 100A forward current, you can handle high-power welding tasks 30% faster than traditional rectifiers. Pair it with its low thermal resistance, and you achieve uninterrupted performance even under prolonged use.
