WAF150 Series

Wide Input Range DC/DC Converter for Railway & Industrial Applications

The WAF150 series is a compact and ruggedised range of DC/DC converters that will deliver 150 W output power for harsh industrial environments. The series features ultrawide input range voltages of 9 to 36 V, 18 to 75 V and 43 to 160 VDC. Available in five single outputs of 12V, 15V, 24V, 28V and 48 VDC, the output can be trimmed up to 20% of nominal.

Features include an operating temperature range of -40 to +100°C ambient; remote ON/OFF; OCP, OVP and OTP protection; and adjustability. The WAF series convection/conduction-cooled package construction makes it suitable for extreme environmental and electrically demanding applications. The fully enclosed and encapsulated converters come in a compact package of 98 x 52 x 17 mm. They comply with the stringent requirements for railway EN50155 standard, vibration MIL-STD-810F and UL 62368-1 approval.
