industrial electronics, mobile telecommunication and
distributed power markets. With a wide input voltage
range of 36-75V they are available with output voltage
of either 1.8, 2.5, 3.3, 5.0, 12, 15, 24 or 28 Volts. All
models feature an input filter, input undervoltage
lockout, output overvoltage and overtemperature
protection, output current limiting and short circuit
protection. The unique open-frame construction with
aluminum heat spreader design achieves efficient heat
transfer with no hot spots.
