240W DIN Rail Supplies Can Take A Good Beating

TRACO POWER’s TIB 240-EX Family of 240W DIN rail power supplies are designed for harsh environments and hazardous locations with certifications for ATEX II3G and UL HazLoc Class I / Div 2 standards. They feature 24 / 48 Vdc outputs (-2% ~ +17% VADJ Range); high efficiency operation of 95%; 150% peak power for 4 seconds; and packaged in a ruggedized metal enclosure that is EN61373 qualified to the rigorous railway shock and vibration standards.  

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°C 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 minimizes 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. For deeper insights, datasheets are available.
