The TXO 300 is a series of AC/DC open frame power supplies with 300 Watt and a 3000 VAC reinforced isolation system. Our TXO line specifically focuses on providing cost efficient industrial power supplies. High efficiency of up to 88% allows a compact design and an operating temperature range of –20°C to +50°C without derating, while going up to +70°C with load derating. They feature remote control, come with an active power factor correction and EMC characteristics dedicated for applications in industrial/automation and test & measurement fields. It makes the products an ideal solution for various industrial and cost sensitive applications.
