Important Selection Guide
1. Choosing the Correct Current Rating
The marked current on the power module is the average on-state value, not the actual long-term effective operating current. Always leave sufficient margin based on your actual working environment:
- Resistive Load: Apply a 2× to 2.5× margin — Actual Current (A) × 2 to 2.5 = Module Nominal Current (A)
- Inductive Load: Apply a 6× to 7× margin — Actual Current (A) × 6 to 7 = Module Nominal Current (A)
2. Heat Sink Configuration
When the actual working current exceeds 5A, a suitable heat sink must be installed to ensure safe and reliable operation. Failure to provide adequate thermal management may reduce component lifespan and performance.
3. Availability & Bulk Orders

Frequently Asked Questions
Q: What is the difference between the MDS 150A, 160A, 200A, and 250A rectifier bridge modules?
A: The primary difference is the nominal on-state average current rating. The 150A model is suited for lower-demand applications, while the 250A model handles higher sustained current loads. All variants share the same three-phase rectifier bridge topology and are available across the same voltage range (1600V–2400V). Always apply the appropriate derating margin based on your load type (resistive or inductive) when selecting the correct module.
Q: Do I need a heat sink for these rectifier bridge modules?
A: Yes. Whenever the actual operating current exceeds 5A, a compatible heat sink is required. The module generates heat during operation, and without adequate thermal management, performance and longevity can be compromised. Choose a heat sink with sufficient thermal dissipation capacity for your specific current and ambient temperature conditions.
Q: Can I use this three-phase rectifier bridge module with an electromagnetic furnace?
A: Yes, the MDS series is specifically suited for use in electromagnetic furnace applications and other induction heating systems. These systems typically involve inductive loads, so remember to apply the 6× to 7× current margin when selecting the appropriate module rating for your furnace's actual operating current.
Q: Are bulk orders or custom configurations available?
A: Absolutely. Standard stock models are available for immediate dispatch. For bulk orders or custom voltage/current specifications, please contact our customer service team with your required quantity and configuration details to confirm availability and lead times.
