DIN rail mount power supplies achieve very high efficiencies

Traco Power has released their TIB Family of DIN Rail Mount Power supplies featuring high efficiencies up to 94.5%. This new generation of DIN-rail power supplies combines the most efficient circuit topology with optimized cost/performance ratio for industrial environments and control cabinets. These products substantially reduce power losses. Their high efficiency enables a slimmer package design with a DIN Rail clip that can be mounted on either the rear (typical installations) or side (flat panel installations) of the power supply with DC-OK LED indicators on both the front and side panels. The product’s reduced heat dissipation enables a -20C to +60C full load operating temperature range and up to 70C with only 20% de-rating. The supplies offer 150% boost power for a minimum of four seconds to support stepper motors, solenoids or actuators with true power-back immunity (no voltage over / under shoot). EMC immunity is compliant for applications in industrial environments (EN 61000-6-2) with emissions compliant with the standard for residential and commercial environments (EN 61000-6-3). The 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. The TIB Family is available in four power ranges of 80W, 120W 240W or 480W with 24VDC outputs (adjustable from 23.5VDC to 28VDC). All models are safety approved to meet UL/EN60950-1 and UL508 listed with compliance to EN61000-6-2 and EN61000-6-3 EMC Standards.
