The products provide onboard conversion of standard telecom and datacom input voltages to two independently-regulated output voltages. Leading-edge technology provides extremely high efficiency and superior thermal performance which enables the products to deliver full-rated power at 55°C ambient temperature with only 200 LFM forced air without the addition of a heatsink. The outputs also track each other during both startup and shutdown.
