ErP directive)** - **High efficiency up to 93%** - **Internal EN 55032 class B filter** - **Protection class II prepared** - **3 year product warranty** UL 62368-1 IEC 62368-1 The TPI 50A-J is a 50 Watt AC/DC open frame power supplies series with a 3000 VAC reinforced isolation system. Our TPI line specifically focuses on providing cost efficient industrial power supplies in compact designs. This series offers a peak power function which enables the unit to deliver up to 140% of the rated power for up to 5 seconds. Excellent efficiency of up to 93% allows a compact design and an operating temperature range (natural convection) of –40°C to +60°C without derating, while going up to +85°C with either load derating or forced cooling. They are designed to meet the ErP directive (< 0.3 W no load power consumption) and come with an EMC characteristics dedicated for applications in industrial/automation and test & measurement fields. High reliability is provided by use of industrial high-quality grade components and an excellent thermal management. It makes the TPI 50A-J an ideal solution for any demanding industrial devices or space critical applications. ## **Models** |**Order Code**|**Output Power**
