MPDCD3-B - CRYDOM

MPDCD3-B Frequently Asked Questions (FAQs)

• What is the maximum surge current that the MPDCD3-B can handle?
  The MPDCD3-B can handle surge currents up to 100A for 10ms, but it's recommended to derate the current to 80% of the maximum rating for continuous operation.
• How does the MPDCD3-B handle overvoltage protection?
  The MPDCD3-B has built-in overvoltage protection (OVP) that triggers when the input voltage exceeds 30V. The OVP circuit limits the output voltage to prevent damage to the load.
• What is the thermal derating curve for the MPDCD3-B?
  The thermal derating curve for the MPDCD3-B is not explicitly stated in the datasheet, but Crydom Inc recommends derating the output current by 1.5% per degree Celsius above 50°C to ensure reliable operation.
• Can the MPDCD3-B be used in parallel for higher current output?
  Yes, the MPDCD3-B can be used in parallel to increase the output current, but it's essential to ensure that the units are properly synchronized and that the output currents are balanced to prevent uneven current sharing.
• What is the recommended PCB layout and thermal management for the MPDCD3-B?
  Crydom Inc recommends a 4-layer PCB with a solid ground plane and a thermal pad connected to a heat sink or a metal chassis for efficient heat dissipation. A minimum of 1 oz copper thickness is recommended for the PCB.
