High-voltage regulated DC-DC converters aimed primarily at electronic engineers designing IT equipment for industrial, instrumentation and transportation applications are available at RS Components. The TRI Series power converters from TRACO Power combine a sophisticated reinforced isolation system, able to withstand high test voltages, with high common-mode transient immunity.

The TRI Series offers five power options: 3.5W, 6W, 10W, 15W and 20W. The first three options, housed in compact 1.25 x 0.80 x 0.40-inch DIP-24 packages, provide 7071VDC regulated I/O isolation and 9000VDC peak isolation of up to one second duration. The 15W and 20W models, with a 2.00 x 1.00-inch footprint, feature 5940VDC I/O isolation and 8000VDC peak isolation up to one second.

All models have a 1000VAC RMS working voltage and common-mode transient immunity (dv/dt) of 15kV/µs.

Other TRI Series characteristics include low no-load power consumption ranging from 96–192mW for 3.5W models to 240–480mW for 20W versions; high efficiencies of up to 90%; and overload, overvoltage and short circuit protection.

Mean time between failure is over one million hours.

TRI Series DC/DC converters offer 12V (9–18V), 24V (18–36V) and 48V (36–75V) input voltage options with a wide 2:1 input range, and precisely regulated output voltages of 5.1V, 12V or 15V single mode or ±12V or ±15V dual mode.

A 4.5–9V input range option is available for 3.5W models.

An internal filter enables all TRI power supplies to comply with EN 55032 class A EMC emission requirements for multimedia equipment used in non-residential environments — including professional IT, broadcast, audio-visual and lighting control products — without any external components.

All models are safety qualified to IEC/EN/UL 62368-1 with IECEE CB Report, operating safely over a wide temperature range from –40°C to +85°C.

All TRI Series DC/DC converters are supported by a three-year warranty provided by TRACO Power. They are stocking now at RS in the EMEA and Asia Pacific regions.
