Question What is R.SMPS Answer The R.SMPS (Regulated Switch Mode Power Supply) is designed to keep supply voltage rails at optimum levels even when the mains voltage drops. Mains voltages can drop as much as 20% below nominal before there is any effect on rail voltages. Thus the R.SMPS can deliver full rail voltage to the output stage at all times, allowing the PLM to exhibit consistent transient response and a clean LF response. The PLM 20000Q is also equipped with a universal power supply with power factor correction (PFC). The device can take any mains voltage, from 65 V to 265 V, allowing it to function worldwide in many different configurations. The PFC reduces current peaks on the lines and reduces the requirements placed on the mains distribution system. The PLM 20000Q has an unparalleled power factor extremely close to one.
