TDK Corporation (TSE 6762) introduced the TDK-Lambda PH600A280-24 DC-DC converter. Rated at 24V 600W, this further extends the 280Vdc nominal input PH-A series from 50W to 600W. The PH-A series is utilized in HVDC (High Voltage Direct Current) equipment for data communications, high voltage transmission, renewable energy applications, robot controllers and factory automation.
Certification to the safety standard EN 62477-1 (Over Voltage Category III) benefits users requiring compliance to the machinery safety standard IEC 60204-1. The PH600A280 does not require an isolation transformer on the distribution panel, reducing cost, size and weight.
The PH600A280-24 accepts a wide range 200 to 425Vdc input delivering 24V at 12.5A. The output voltage can be set between 14.4 and 28.8V using the trim terminal. With an efficiency of 93%, the module can operate at full load with baseplate temperatures of -40°C to 85°C, derating linearly to 80% load at 100°C. Conduction cooling through the baseplate enables the PH-A to be used in outdoor sealed enclosures or liquid cooled equipment.
