UWS-5/10-Q48P-C

The world of “brick” DC-DC converters has seen a steady size reduction. The UWS series makes another dramatic size shrink down to a “sixteenthbrick” width (0.90 inches) while still retaining a high power output and full 2250 Volt DC isolation. The PC-board mount converter family accepts 18 to 75 Volts DC inputs and delivers fixed outputs regulated to within ±0.125%. The UWS converters are ideal for datacom and telecom applications, cell phone towers, data centers, server farms and network repeaters.UWS outputs may be trimmed while delivering fast settling to current step loads and no adverse effects from higher capacitive loads. Excellent ripple and noise specifi cations 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.Many self-protection features on the UWS series avoid both converter and external circuit hazards. These include input undervoltage lockout and overtemperature shutdown. The output of these DC-DC converters have current limit using the “hiccup” autorestart technique and the outputs may be short-circuited indefi nitely. Additional features include output overvoltage and reverse conduction elimination.The synchronous fl yback topology yields high efficiency for minimal heat buildup and “no fan” operation.
