bcd20020-g rev ab1, 17-nov-09 page 4 of 25 www.power-one.com ? w series data sheet 125, 250 watt ac-dc and dc-dc din-rail converters functional description the w series converters are primary controlled ac-dc or dc- dc flyback converters with a constant switching frequency of 130 khz. the power-factor-corrected single-step conversion of the input voltage to a low output voltage results in extremely high efficiency. depending upon the output power, the converters are fitted with one (125 w) or two (250 w) powertrains. models with two powertrains have one or two outputs. double-output models exhibit indiviually regulated powertrains. the input voltage is fed via fuse, filter, and rectifier to the main transformer, designed in planar technique. the input filter with very small input capacitance generates virtually no inrush current. an input transient suppressor protects the converter against high voltage peaks and surges. input over- and undervoltage lockout as well as input current limitation protect the converter from operation outside of its specification. the input voltage waveform is sensed by the primary control logic to allow active power factor correction, forcing the input current to follow the input voltage waveform. the secondary side of the main transformer supplies via the rectifier diode a large electrolytic output storage capacitor providing for the hold-up time. double-output models exhibit an individual control logic each. the output voltage and the output current are measured and fed back to the primary control logic via an optocoupler. a second control loop monitors the output voltage. it disables the output in the case of a failure in the control logic and limits the output voltage. built-in temperature sensors monitor the internal temperature of each powertrain. if the temperature exceeds the limit, the converter reduces the output power continuously to keep the temperature below its limit. a green led on the front cover confirms the presence of the output voltage(s). the r input (option r, m1, or m2) allows for external adjustment of the output voltage by means of a resistor or an external voltage source. an external sensor can be connected to the r input and allows for temperature-controlled battery charging (see accessories). fig. 1 single-output converters (125 w). product marking basic type designation, applicable safety approval and recognition marks, ce mark, warnings, pin designation, power-one company logo. specific type designation, input voltage range, nominal output voltages and currents, degree of protection, batch no., serial no., and data code including production site, version, and date of production. input filter input filter v o /i o control output filter 2 nd control loop (selv) control circuit including pfc and input ovp/uvp l n vo+ voC c y c y c y c y c y aux fuse 2 nd fuse (option f) 2 1 03103b shunt shunt 3 4 5 8 9 2 3 6 7 1 11 10 viC vi+ rectifier 1 + 1 ew models have a link or a decoupling diode (opt. q) in the vi+ line.
