DC/DC Converter TRI 3 Series, 3.5 Watt Reinforced I/O-isolation 5000 VAC rated for 1000 VAC working voltage Ultra-high isolation peak voltage 9000 VDC (1s) Common Mode Transient Immunity (dv/dt) 15 kV/s Operating temperature range -40 to UL 62368-1 IEC 62368-1 +90C The new TRI 3 is a high isolation, regulated 3.5 Watt DC/DC converter series Low no-load power consumption 96 which comes in a compact DIP-24 package. The core characteristic of the TRI 192 mW 3 series is a sophisticated reinforced isolation system which is able to with- stand high test voltages (9000 VDC for 1s and 5000 VAC for 60s) and working Internal EN 55032 class A filter voltages (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 87% integrate an EN 55032 class A filter and greatly reduces the no-load power 2:1 input voltage range: 4.5-9, 9-18, consumption. High efficiencies up to 87% allow safe operation from 40C to 18-36, 36-75 VDC +90C without derating. All models have a wide 2:1 input voltage range and precisely regulated, isolated output voltages. With the latest IT safety certifica- Protection against overload, overvoltage tions (IEC/EN/UL 62368-1) the TRI 3 series is the perfect choice for many de- and short circuit manding applications in the industrial, transportation and instrumentation sec- 3-year product warranty tors.
