Manufacturer profiles associated with Voltage Sensing Circuit.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The input voltage range is 3.3 to 30 V DC, as listed in the directory. This is the operating range for monitoring; confirm the exact range for your specific model with the manufacturer.
The circuit continuously measures battery voltage and provides a signal to the charge controller. When voltage thresholds are crossed, the controller triggers actions to prevent overcharge or deep discharge, such as switching to float charging or disconnecting the load.
Hysteresis (0.5% to 2%) prevents oscillation at the threshold by requiring the voltage to change by a certain amount before the output switches back. This ensures stable operation in noisy environments.
The ESD rating of ±2 kV (human body model) per IEC 61000-4-2 is a reference value from the directory. It indicates the level of robustness tested, but it does not certify that a specific product is compliant. Always verify with the legal manufacturer or supplier.
