AC/DC Power Supply TPI 125A-J Series, 125 Watt 125 Watt open frame power supplies in a 3 x 2 package Compact and cost efficient design Peak power function up to 120% I/O reinforced isolation 3000 VAC Operating temperature range 40C to +85C No load input power <0.3W (acc. ErP directive) High efficiency up to 92% Internal EN 55032 class B filter Protection class II prepared UL 62368-1 IEC 62368-1 3 year product warranty The TPI 125A-J is a 125 Watt AC/DC open frame power supplies series with a 3000 VAC reinforced isolation system. Our TPI line specifically focuses on pro- viding cost efficient industrial power supplies in compact designs. This series offers a peak power function which enables the unit to deliver up to 120% of the rated power for up to 10 seconds. Excellent efficiency of up to 92% allows a compact design and an operating temperature range (natural convection) of 40C to +50C without derating, while going up to +85C 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 dedicat- ed 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 125A-J an ideal solu- tion for any demanding industrial devices or space critical applications. Models Order Code Output Power Output Voltage Output Current max. Output Current max.
