High-Isolation 3- to 20-Watt DC-DCs with 1000 VACrms Working Voltage

The new TRI line from Traco Power comprises a set of high isolation, regulated dc-dc converter series which come in compact DIP-24 (3- to 10-Watt) or 2″x1″ (15- to 20-Watt) packages. The core characteristic of the TRI line is a sophisticated reinforced isolation system which is able to withstand high test voltages (9000Vdc for 1s and 5000Vac for 60s) and working voltages (1000Vac).

Complementing this isolation characteristic is a high Common Mode Transient Immunity of 15kV/µs. With the latest IT safety certifications (IEC/EN/UL 62368-1) the TRI line is the perfect choice for many demanding applications in the industrial, transportation and instrumentation sectors.

The new design allows to fully integrate an EN 55032 class A filter and greatly reduces the no-load power consumption. High efficiencies up to 90% allow safe operation from -40°C to +85°C. All models have a wide 2:1 input voltage range and precisely regulated, isolated output voltages.
