T Series Data Sheet 500 Watt AC-DC Converters Features Universal AC input range 70 to 255 VAC with PFC Class I equipment DC output for 24 and 48 V loads Battery charging for 24 and 48 V batteries with remote temperature control 4 kVAC I/O electric strength test voltage Telecom rectifier applications Very high efficiency, typically 93% Power factor >0.96, harmonics according to IEC/EN 61000-3-2, low RFI No inrush current, hot swap capability High power density, rugged mechanical design, all boards covered with a protective lacquer Very compact 19 cassette (28 TE, 3 U, 160 mm) Safety according to IEC/EN 60950-1 and UL/CSA nd 60950-1 2 Ed. 111 4.4 3 U 141 5.6 168 28 TE 6.6 output voltage is backed-up by a battery. The float charge of the Description battery can be set by a cell-voltage selector switch according to The T Series converters are electrically isolated AC-DC the battery type used. These converters are equipped with a converters with an output power of up to 550 W. For higher temperature sensor input, in order to improve the life power requirements several converters may be connected in expectancy of the battery. parallel. The rectifier models are suited for DC-bus applications at The input is ideally adapted to the mains: Full power factor constant voltage. As the output voltage is SELV, even correction, no inrush current, low RFI level, and high transient electrically non-isolated switching regulators, such as the PSx and surge immunity are key design features. A T Series models, may be connected to the output. converter behaves similar to a resistive load. The LT/UT1701 models are especially optimized to build The LT models can be operated from a universal AC-input distributed power systems together with the 48Q, CQ, or CP range from 85 to 255 VAC. It is the preferred type for 230 VAC Series DC-DC converters, as the signalling capabilities of mains, whereas the UT models are optimized for 110/ both families are matched. Distributed power systems have 120 VAC mains. The output delivers an electrically isolated as one advantage less power losses over load lines and fewer Safety Extra Low Voltage (SELV) and is short-circuit and no- regulation problems. load proof. Depending on the type, two output characteristics Power-One also offers backplanes for fast and simple set-up are available, intended either for rectifier applications or for of 19 DIN-rack systems with T Series converters see battery charging purposes. Accessories.
