muRata ULS-3.3/30-D48N-C

The new ULS 100 Watts series offers output voltages of 3.3Vout (30A), 5Vout (20A), 6.5Vout (15A), and 12Vout (8.3A). The ULS sixteenth - brick series maintains a width of 0.9 inches while still retaining up to 100 Watt output and full 2250 Volt DC isolation. The PC - board mount converter family accepts 36 to 75 Volts DC inputs and delivers fixed outputs regulated to within ±0.2%. The ULS converters are ideal for datacom and telecom applications, cell phone towers, data centers, server farms and network repeaters. ULS outputs may be trimmed within ±10% of nominal output while delivering fast settling to current step loads and no adverse effects from higher capacitive loads. Excellent ripple and noise specifications assure compatibility to circuits using CPU’s, ASIC’s, programmable logic and FPGA’s. No minimum load is required. For systems requiring controlled startup/shutdown, an external remote On/Off control may use a switch, transistor or digital logic. Remote Sense inputs compensate for resistive line drops at high currents. Many self - protection features on the ULS series avoid both converter and external circuit hazards. These include input undervoltage lockout and overtemperature shutdown. The output current limit uses the “hiccup” autorestart technique (i.e., the outputs may be short - circuited indefinitely). Additional features include output overvoltage protection too. The synchronous rectifier topology yields high efficiency for minimal heat buildup and “no fan” operation.
