Green Watt Power, a division of Powerland that manufactures EV chargers and DC/DC converters in California, has announced a new series of IP67-rated DC/DC converters for EVs.

The fully enclosed, IP67-ruggedized EVD500 Marble Series offers two DC input ranges featuring output voltages of 12 V and 24 V to power auxiliary EV functions such as lights, instruments and accessories. It has Enable/Remote on/off and a quiescent current draw of less than 30 µA for low battery conservation. The EVD500 Marble Series is input-to-output isolated and protected against input under-voltage lockout, reverse polarity, over-voltage, short-circuit and over-temperature.

Main features include:

• DC input ranges of 30-65 V and 50-130 V
• DC output voltage of 13.5 V or 27.5 V
• Output power of 500 W to 5,000 W with parallel connection of up to 10 units
• Efficiency of up to 93%
• All-around protections: IRPP, UVLO, OVP, SCP, OTP
• 1.5 kV input-to-output isolation test voltage
• Designed to meet IEC, UL and CSA safety requirements
• Wide working temperature: -40 °C to +85 °C Tc
• Available with Molex connector or flying leads

“Unlike most DC/DC converters in the EV market, the EVD500 has a constant current function, so it can connect directly to a battery load,” the company said.
