SmartPass 120S

Stand-alone DC Battery Management System

the latest improvements in DC charging see the SmartPass 120S now being a stand-alone model which can provide 120A DC power charging to your house bank. The wide DC input range means even smart alternator vehicles won't be able to slow this charging process down. With an isolated low voltage disconnect circuit, you can ensure essential communication or navigation lights are left running while non-essential equipment is turned off to save the batteries power.

The SmartPass 120S includes the emergency jump start feature which was introduced in the SmartPass 120 model to get you out of situations where you've flattened the start batteries using a winch or leaving the ignition.

• Smart alternator compatible
• Compatible with D250SA and D250SE for the ultimate 140A power management solution
• Start assistance function
• Battery separation eliminates diodes and VSR relays
• Fully automatic
• Maximizes battery life
• Battery Guard to protect your secondary battery from total discharge
• Dynamic over current protection to handle temporary inputs and outputs of up to 350A for fast charging
• Battery temperature protection for added safety
