The PFU-3 DC sampling module is designed for use with Emerson's PSM-E11 and PSM-E20 DC panel monitoring units. The function of the PFU-3 DC voltage sampling box is to convert high-voltage DC signals into input signals that can be collected by the power distribution monitoring board. In power operation systems, the output voltage is relatively high. To achieve isolation between the detection signal and high voltage, while eliminating the high common-mode signals generated by the DC output ground, this dedicated DC voltage sampling box is employed. It utilizes isolated operational amplifiers to achieve electrical isolation between high and low voltages and signal sampling. The sampled weak signal is linearly amplified and compensated before being converted into a DC voltage signal, which is then directly sent to the monitoring unit or power distribution monitoring box for processing.
