| Q1: What makes 800A a significant threshold for a DC rectifier? |
| A: 800A represents a tier of power required for starting the largest diesel engines, charging massive battery banks in minutes, or driving high-energy industrial processes. It signifies a transition from standard industrial equipment to specialized, high-power infrastructure. |
| Q2: Can this rectifier be used in a parallel/redundant configuration? |
| A: Yes, it is designed with peer-to-peer parallel capability. Multiple units can be connected to share load for higher currents or to provide N+1 redundancy for critical applications where zero downtime is required. |
| Q3: What are the specific cable requirements for the 800A DC output? |
| A: It requires heavy-duty, finely-stranded copper cables, typically two sets of 500 MCM or equivalent, per terminal. Proper crimping, insulation, and routing to manage electromagnetic forces are crucial. We provide detailed specification sheets. |
| Q4: How is heat dissipation managed at full load? |
| A: The unit employs a multi-zone, forced-air cooling system with high-static-pressure fans and an optimized, finned-aluminum heatsink design. Airflow is front-to-back, making it suitable for racking in a controlled airflow environment. |
| Q5: Is customization available for different voltage/current ratings? |
| A: Absolutely. The 28VDC 800A is a standard high-power model. We engineer custom rectifiers from 100A to several thousand amps, and from 12VDC to 600VDC, tailored to unique project specifications. |
