Inhibit
The inhibit function prevents electric vehicles from moving while charging, which prevents accidental damage to the connected cabling system. The inhibit port contains a 20A relay that closes when connected to A/C power and disables the vehicle.
Supply Mode
Supply Mode converts the industrial battery charger into a constant current, constant voltage power supply for zero voltage charging for troubleshooting low voltage batteries or equalizing unbalanced battery system for longer battery life.
Repair Mode
Repair Mode is an advanced battery recovery tool used to remove sulfated batteries, and regain lost battery capacity. It uses a combination of high voltage and low current to melt down sulfation and return it to the active material again.
Ingress Protection
Industrial battery charger applications get exposed to some of the toughest, and most extreme operating environments. Whether an on-board or off-board application, these chargers are shock, vibration, water, dirt and dust proof and rated at IP66.
