The DRB series will operate across a wide range input voltage of 85VAC to 265VAC and can withstand voltage surges of 300VAC for five seconds. The DRB is available in four package sizes – 15, 30, 50, & 100 Watts and the series covers four output voltage ranges - 5, 12 to 15, 24 to 28, & 48 Volts. Not all voltages are available in each power level. Because of the high efficiency of the product line, waste heat is reduced allowing the package size to be smaller without compromising reliability.
