Features

◆ Semi-regulated output (load) ◆ Industry standard pinout ◆ High efficiency up to 88.5% ◆ Single and dual output models ◆ I/O isolation voltage 1000 VDC ◆ Operationally reliable up to 5‘000m altitude ◆ Operating temperature range –40°C to +95°C ◆ 3-year product warranty The TRA 1 series are miniature, I/O-isolated 1W DC/DC-converters with a semi load regulation. They are the ideal solution to power drivers and circuits where unregulated DC/DC converters do not meet the input voltage range at load change.
