TRA 1-1211 TRACO Power

DC/DC Converters TRA 1 Series, 1 Watt CB Scheme UL 60950-1 Features Semi-regulated output (load) Industry standard pinout High efcfi iency up to 88.5% Single and dual output models I/O isolation voltage 1000 VDC Operationally reliable up to 5000m altitude Operating temperature range 40C to +95C 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.
