High isolation, regulated DC/DC converters in compact package


TRACO Power’s new TRI line comprises high isolation, regulated DC/DC converters that come in compact DIP-24 (3-10 Watt) or 2”x1” (15-20 Watt) packages.

The core characteristic of the TRI line is a sophisticated reinforced isolation system which is able to withstand high test voltages (9000 VDC for 1s and 5000 VAC for 60s) and working voltages (1000 VACrms). Complementing this isolation characteristic is a high Common Mode Transient Immunity of 15 kV/µs.

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. 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.
