DC/DC Converter TRI 20 Series, 20 Watt Reinforced I/O-isolation 4200 VAC rated for 1000 VAC working voltage Ultra-high isolation peak voltage 8000 VDC (1s) Common Mode Transient Immunity (dv/dt) 15 kV/s Operating temperature range -40 to UL 62368-1 IEC 62368-1 +76C The new TRI 20 is a high isolation, regulated 20 Watt DC/DC converter series Low no-load power consumption 240 which comes in a compact 2x1 package. The core characteristic of the TRI 20 480 mW series is a sophisticated reinforced isolation system which is able to withstand high test voltages (8000 VDC for 1s and 4200 VAC for 60s) and working volt- Internal EN 55032 class A filter ages (1000 VACrms). Complementing this isolation characteristic is a high Common Mode Transient Immunity of 15 kV/s. The new design allows to fully High efficiency up to 90% integrate an EN 55032 class A filter and greatly reduces the no-load power 2:1 input voltage range: 9-18, 18-36, consumption. High efficiencies up to 90% allow safe operation from 40C to 36-75 VDC +55C without derating and up to +76C with derating. All models have a wide 2:1 input voltage range and precisely regulated, isolated output voltages. With Protection against overload, overvoltage the latest IT safety certifications (IEC/EN/UL 62368-1) the TRI 20 series is the and short circuit perfect choice for many demanding applications in the industrial, transportation 3-year product warranty and instrumentation sectors.
