The GPS-x303 series of linear programmable power supplies is available in 2-4 channels , with maximum outputs of 180W and 200W. Overload protection , reverse polarity and an output on/off switch protect the GPS series and their load from unexpected conditions. A 'high regulation capability (0.01% + 3mV) and low ripple/noise value (<1mVrms, 5Hz ~ 1MHz) are typical for the two channels in constant voltage mode. Automatic control of the speed of the cooling fan according to load conditions allows its noise to be minimized, ensuring quiet operation. The GPS-x303 series are the ideal solution for benchtop applications. The power supplies are portable , lightweight , economical and offer multiple outputs.
