Emerson DC Voltage Sampling Box PFU-3 High-performance Original DC Panel PFU-3
Product name: DC voltage sampling box
Product Model: PFU-3,
Brand: Emerson, USA
Function:
The basic function of the DC voltage sampling box is to convert the DC high-voltage signal into the input signal that can be collected by the distribution monitoring board. Since the output voltage is relatively high in the power operation power supply, this special DC voltage sampling box is adopted in order to realize the isolation of the detection signal and the high voltage, and to consider eliminating the high common-mode signal generated by the DC output floating. Dc voltage sampling box uses isolated operational amplifier to realize electrical isolation of high and low voltage and signal sampling. After linear amplification and compensation, the sampled weak signals are converted into DC voltage signals and sent directly to the distribution monitoring box for processing.
Technical parameters:

Input voltage range: DC 0 ~ 300V;
Output voltage amplitude: 0 ~ 5V, adjustable output;
Appearance: 136*58*36, installation size: 125*45
