    Tips: Application of battery voltage sensor

    With the development of industry, people pay more and more attention to the development of power. Among them, UPS (Uninterruptible Power Supply) is used more and more. Battery monitoring becomes the last barrier to ensure power operation.
    The measurement of battery pack voltage is sometimes difficult, because some UPS do not effectively filter the harmonics loaded into the battery during double conversion processing, resulting in the terminal voltage loaded at both ends of the battery containing a lot of harmonic components. This makes voltage measurement very difficult. At the same time, the measurement of the internal resistance of the single battery in the whole group of batteries, the measurement of the single battery voltage and even the transmission of the communication system have caused a lot of trouble. Effective and reliable monitoring of the battery pack voltage is a problem that needs to be solved, and the battery voltage sensor can avoid such high-frequency harmonic components.
    The measured voltage enters through the terminal input of voltage sensor, passes through the photoelectric isolation element, thus realizes the isolation measurement of the primary voltage, and after appropriate transformation, outputs a standard signal proportional to the DC voltage of the primary side, such as DC 0-5V, 0-10V, 4-20mA, etc.
    Because the photoelectric isolation element is not sensitive to AC harmonic components, the harmonics loaded by the high-frequency UPS to both ends of the battery will not have any adverse effect on the output of the voltage sensor, so the voltage sensor of this principle has a natural shielding against high-frequency harmonics. It shows good adaptability in a large number of practical applications. It is very important to monitor the battery pack effectively and reliably. For the monitoring of group voltage, the battery voltage sensor has unique special advantages, which can be very convenient to use in the measurement environment with high interference.

    The limits of voltage sensor
    I have the bidirectional voltage sensor to measure 500V DC to 500V DC and output 5 to 5V DC signal via DAC. It requires a power supply of 24V DC.
    My question is, what are the limits of this spec I have a 24V DC PSU that outputs 27V DC, will that work?

    The positive and negative deviation of the power supply does not exceed 10%, so 27V cannot be used as a power supply, and the voltage is a little higher.
