SUNNYVALE, CALIF. The three-member MV380 Megaverter Series of 520- to 600-W dc/dc full-brick converters from RO Associates is designed for circuit board mounting in telecom and other distributed power or centralized modular power applications.
They convert a 380-Vdc input to 26, 48 or 56 V out at 88 to 92 percent efficiency. The modules use a low-noise ZVS architecture and can be paralleled for n+m redundancy.
Other features include nonshutdown overvoltage protection, logic on/off, current-limiting and overtemperature shutdown at 105 degrees C. Output voltage can be externally trimmed. The modules are UL/CSA/TUV compliant. Input-to-output isolation is 4.5 kVdc. Pricing in single piece quantities is $225. They sell for $199 each in hundreds. Availability is from stock to 6 weeks.
