⚠️ Important Selection & Usage Notes

1. Current Rating Selection

The rated current shown on the module is the average on-state value, not the continuous RMS operating current. Always leave adequate margin based on your actual load and environment:

• Resistive Load: Select a module rated at 2–2.5× your actual operating current (e.g., 10A load → choose 20A–25A module)
• Inductive Load: Select a module rated at 6–7× your actual operating current (e.g., 10A load → choose 60A–70A module)

2. Heat Sink Required

If the actual working current exceeds 5A, a properly rated heat sink must be fitted to ensure safe, stable long-term operation and prevent thermal damage.

3. Stock & Bulk Orders

Standard models are held in stock and available for immediate dispatch. For large-quantity orders, please contact customer service to confirm availability and delivery schedule before placing your order.

Typical Applications

• Industrial motor drives and variable-frequency drives (VFDs)
• Welding machine power supplies
• Battery chargers and DC power supplies
• Elevator and crane control systems
• Electroplating and electrolysis equipment
• Three-phase AC-to-DC conversion in power electronics

Frequently Asked Questions

Q: What is the difference between MDS60-16 and MDS100-16 three-phase rectifier modules?

A: Both are three-phase diode bridge rectifier modules in the MDS series with a 1600V voltage rating. The primary difference is the current rating: MDS60-16 is rated for 60A, while MDS100-16 is rated for 100A. Choose your module based on your application's load current — and remember to apply the recommended safety margin (2–2.5× for resistive loads, 6–7× for inductive loads).

Q: Do I need a heat sink with this three-phase rectifier module?

A: Yes. Any time the actual working current exceeds 5A, a suitable heat sink must be installed. Without adequate thermal management, the module may overheat during continuous operation, reducing performance and lifespan. Always select a heat sink appropriate for your module's current rating and ambient temperature.

Q: Can the MDS rectifier module handle both resistive and inductive loads?

A: Yes, the MDS series three-phase diode bridge rectifier modules can handle both resistive and inductive loads. However, inductive loads (such as motors and transformers) require a significantly higher module current rating — typically 6 to 7 times the actual working current — due to inrush and reactive current considerations. Always verify your load type before selecting a module.

Q: Is this rectifier module available for bulk or custom orders?

A: Yes. Standard current ratings (30A, 50A, 60A, 75A, 90A, 100A, 120A, 150A) are available from stock. For bulk orders or custom specifications, please contact customer service with your required quantity and rating so delivery time can be confirmed.
