DC/DC Converters TEN 50WI Series, 50 Watt g CpBendin Features ◆ Highest power density: Scheme 50 W in 1” x 2” x 0.4” package ◆ Ultra wide 4:1 input range ◆ Excellent efficiency up to 92 % ◆ Operating temperature range –40°C to +60°C ◆ Protection against over-temperature ◆ No minimum load required ◆ Output voltage adjustable ◆ Remote On/Off ◆ I/O isolation 1500 VDC ◆ 3-year product warranty The TEN 50WI Series is a range of isolated high performance dc-dc converter modules. Due to the very high efficiency of up to 92% and the use of highest reliable components these 50 W converters come with a footprint of only 1.0” x 2.0”. The 10 models have a wide 4:1 input voltage range and a tight output voltage regulation. They do not need a minimum load and a offer a high efficiency also at low load conditions. The output voltage is adjustable by external resistor. Remote On/Off and protection against overload and short circuit are standard features of these converters. Typical applications are in mobile equipment, instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is critical.
