Operating from 200–425 Vdc input, PH-A280 series offers 50, 75, 100, and 150 W output power levels and nominal output voltages of 3.3, 5, 12, 15, 24, 28, and 48 Vdc. Latter figures are adjustable from -20% to +10% (±20% for 5 V output models), and efficiencies reach up to 90%. Operating from -40 to +100°C, quarter brick (37.2 x 12.7 x 58.3 mm) series comes with remote sense, remote on/off, overvoltage, and overcurrent protection circuitry as well as input-to-output isolation of 3 kVAC.
