TXH 240-148 TRACO Power

Metal Case Power Supplies TXH Series, 120 480 Watt CB Scheme UL 60950-1 Features Compact U-bracket and enclosed power supplies Screw terminal block Very high efcfi iency up to 93 % No internal fan for 120 W & 240 W models. Universal input 90 264 VAC Adjustable output voltage EMI/EMC compliance with EN 61000-6-3 and EN 61000-6-1 Compliance to EN 61000-3-2 (PFC) Short circuit and overvoltage protection 3-year product warranty The TXH series is a family of power supplies in metal enclosure, designed for a wide range of cost critical applications. The very high efcfi iency of up to 93% admits of a compact design with free air convection coouling for the 120 and 240 Watt models. The units are equiped with screw terminal blocks and are easy to install in any equipment. These power supplies have universal input and comply with European EMC stan- dards and the Low Voltage Directive (LVD).
