DC80W
80 Watt
- Extremely small and space saving
- High efficiency up to 90 %
- Ideal for low-budget applications
The extremely flat and very slender ATX DC/DC converter has been designed for installation in closed, fanless box computers. It is characterized by a very high efficiency and a low thermal dissipation rate. Due to its robust construction and high-quality components it is ideal for implementation in industrial and medical devices. A firmly connected cable harness is standard.
