The TDK-Lambda DRF series will operate across a wide range of input voltage, 85 to 264VAC, and can withstand voltage surges of 300VAC for five seconds. The DRF is available in three package sizes – 120, 240, and 480 watts with an output of 24V. Because of the high efficiency of the product line waste heat is reduced, allowing the package size to be smaller without compromising reliability.
