CSNV500M-152G
Key Attributes
Model Number:
CSNV500M-152G
Product Description
Overview
The CSNV500 series current sensors utilize a closed-loop principle with temperature calibration technology, operating on a single power supply with CAN bus output. Designed for automotive applications, they measure peak DC, AC, or pulsating currents up to 500A. The CSNV500M features a 6.5mm standard mounting hole, while the CSNV500N offers a reinforced 4.3mm mounting hole.
