Power supplies ruggedised for railway shock

The release of the TIB 80-EX Family of 80W DIN rail power supplies has been announced by TRACO POWER. The power supplies are designed for harsh environments and hazardous locations with certifications for ATEX II3G and UL HazLoc Class I / Div 2 standards. 

These products feature 12, 24, 48V outputs (-2% ~ +17% VADJ Range), high efficiency operation of 88 to 90%, 150% peak power for four seconds, and packaged in a ruggedised metal enclosure that is EN61373 qualified for railway shock and vibration.

Protection circuits include back power immunity, short-circuit / overload protection and a DC OK dry signal contact. DC-OK LED indicators on both the front and side panels with optional side panel mounting enable use in flat panels.

The product’s reduced heat dissipation enables a -40 to +60°C full load operating temperature range (up to +70°C operation with only 20% de-rating). Outputs are radio-interference-suppressed to impede radiation at long output lines. This filter reduces the common mode current to within limits of telecommunication ports.

The units operate with a high power factor of up to 99% with active power factor correction which also minimises input inrush current. All models are safety approved to meet UL/EN 60950-1, UL508 listed, EN 600079-0/-7/-15, ATEX II3G and UL HazLoc Class I, Division 2 with EN55032 Class B for both radiated and conducted emissions. High reliability of greater than one million hours per IEC 60079-0 is supported by TRACO POWER’s extended five year product warranty.

Products are in stock and available through distributors around the globe with manufacturing lead times of 12 to 14 weeks.
