The PH1200A280-28 is a 1200W isolated DC-DC converter with a 28V nominal output, adjustable from 16.8V to 33.6V, designed for input voltages of 200 to 425VDC. It operates at 94% efficiency with a maximum input current of 4.61A at 280VDC input under full load. The converter includes remote sense, remote on/off, an inverter good signal, and a 12V auxiliary output, with internal ORing FETs for parallel or N+1 redundant operation. It supports conduction cooling or optional heatsinks, has a baseplate temperature range of -40 to +100°C, and measures 116.6 x 61 x 12.7mm. Safety certifications include IEC/UL/CSA/EN62368-1
The isolated PH-A DC-DC converters have output power levels of 50W, 75W, 100W, 150W, 300W, 600W and 1,200W and accept a wide 200 to 425Vdc input. The range is available with multiple output voltages; 3.3V, 5V, 12V, 15V, 24V, 28V, 36V and 48V. For non-standard outputs, they feature a wide adjustment range of up to -60% to +20%. All models feature remote sense and remote on/off and can be conduction cooled to a cold plate or mounted with optional heatsinks. The PH-A models have efficiencies of up to 94% and can operate with baseplate temperatures of up to -40 to +100°C for use in harsh environments. Applications include custom power supplies, high voltage DC distributed power architecture systems in high power semiconductor test equipment, plus data communications, power transmission, industrial and renewable energy.
