High Slew-Rate Option For Power supplies

With the high slew-rate option, Magna-Power Electronics power supplies standard output stage, designed to provide the lowest possible output voltage ripple, is exchanged for low capacitance film and aluminum electrolytic capacitors and lower loss bleed resistors. As a result, faster voltage and current transitions can be realized: voltage slew rate down to 4 ms and bandwidth up to 60 Hz. Applications for the high-slew rate option include battery charging, photovoltaic emulation, power waveform generation, medium speed power pulsing, and laser diode powering.

All Magna-Power Electronics power supplies come standard with isolated digital and analog programming, enabling voltage and/or current to be driven by a 0-10 V analog signal. It is possible to superimpose waveforms or produce a medium speed pulse on top of the dc output and expect normal capacitor life. With standard models available up to 4000 Vdc and currents up to 24000 Adc, the new option enables high performance at the cost and size of switched-mode power processing.
