Rail power supplies harsh environment and hazardous location qualified

21-05-2019 | Traco Power | Power

Traco Power has released their TIB 240-EX Family of 240W DIN rail power supplies that are constructed for harsh environments and hazardous locations with certifications for ATEX II3G and UL HazLoc Class I/Div 2 standards.

These products are the new leaders of industrial power featuring 24/48VDC outputs (-2% ~ +17% VADJ Range); high-efficiency operation of 95%; 150% peak power for four seconds; and packaged in a ruggedised metal enclosure that is EN61373 qualified to the uncompromising railway shock and vibration standards. Protection circuits comprise back power immunity, short-circuit/overload protection and a DC OK dry signal contact. DC-OK LED indicators on both the side and front panels with optional side panel mounting allow use in flat panels. The product’s reduced heat dissipation enables a -40C to +60C full load operating temperature range (up to +70C operation with just 20% de-rating). Outputs are radio-interference-suppressed to block radiation at long output lines. This filter lowers the common mode current to inside limits of telecommunication ports. The products work with a high power factor of up to 99% with active power factor correction which also decreases input inrush current. All models are safety approved to satisfy 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 the company’s extended five-year product warranty.
