The ECBD014 three-phase AC current sensor transmitter is a device that converts AC current into standard DC current and outputs isolated analog or digital signals.
It is used for measuring three-phase AC current, and is especially suitable for power-frequency 50Hz sinusoidal three-phase AC current.
The product is widely applied in various locations where three-phase AC current measurement is required.
• 35mm standard mounting slot.
Adopts international standard DIN-rail mounting with a retractable locking clip for easier installation.
• High-quality pure copper coil.
Safer than copper-clad aluminum coils, with faster conversion speed and higher stability.
• High-quality wiring terminals.
Provide excellent electrical conductivity and corrosion resistance.
Comply with U.S. UL safety standards, using copper-zinc spring contacts for long service life.
• Imported operational amplifier chip.
Uses an imported U.S. IN chip, offering high stability and extended service life.
