300W DC/DC for E-Mobility with Standard Footprint and IP67

300w-marble-dcdcFeb. 08, 2024. Green Watt Power, a division of Powerland Technology Inc., announces the EVD300 Watt DC/DC converters as extensions of the successful Marble™ Series. The fully encapsulated, IP67 class ruggedized DC/DC converters are designed for Electric Vehicle applications having two DC input ranges covering 30-130V, with output voltages for 12V and 24V batteries used to power auxiliary EV functions such as lights, instruments, accessories, and similar. In addition, unlike most DC/DC converters in the EV market, the Marble™ Series has a constant current function, so it can connect directly to a battery load. Additional features include Enable/Remote on/off, superior low battery conservation with a Quiescent Current draw of less than 30uA and IP67 ingress protection.

The EVD300 Marble™ Series is fully input-to-output isolated and protected by, Input Under Volage Lockout, Reverse Polarity, Over Voltage, Short Circuit and Over Temperature Protection. Two options are offered for connecting the DC/DC converter, either via flying leads or via standard Molex connector.

Top Features:

  • Two DC Input Ranges: 30-65V and 50-130V
  • Two DC Output Voltages: 13.2V or 24V
  • Output Power of 300W, parallel connecting up

to 10 Units with up to 3000W

  • High Efficiency, up to 93%
  • Fully Protected with UVLO, OVP, SCP, OTP, IRPP
  • 1500V Input-to-Output Isolation
  • Designed to Meet IEC, UL, and CSA Safety
  • Operating Temperature: -40oC to +85oC
  • Available with Molex Connector or Flying Leads
  • IP67 Rated Enclosure
  • Industry Standard Size and Footprint

The company’s advanced automation manufacturing facilities allow Green Watt Power/Powerland to provide the highest quality products for the lowest possible cost. Parts are available direct for high-volumes OEM’s, or through the Digi-Key website with lead times from stock to 8 weeks.
