Efficiency is the name of the game for PS5R-V. Improvements in operating efficiency and size lead to performance improvements. These improvements include expanded operating temperature range and a MTBF of up to 900,000 hours! Altogether, these improvements mean PS5R-V is an unmatched value. The PS5R-V series boasts numerous worldwide approvals and certifications, including UL 508. All models under 100W are UL1310 Class 2 approved. Specialized approvals include Class I Division 2 for use in hazardous locations as well as SEMI F47 for use in sensitive equipment applications. With CE approval and RoHS compliance, the PS5R-V series is truly a global product. Continuing the PS5R tradition, the PS5R-V series has spring-up screw terminals, fused inputs and overload protection. They are DIN Rail or direct surface mountable [6 directions!] and have universal [85 - 264V AC] voltage inputs. No derating means you save money, space and time. Thanks to all of these improvements, IDEC offers a 5 year factory warranty on all PS5R-V power supplies.
