C85107

The Battery Protector 300 is a fully automatic battery protector for mobile homes and boats as well as fire, rescue and emergency vehicles, which can also be used as a powerful switching module. It consists of a high-current relay designed for switching currents of up to 300 A (permanent, 600 A for 20 seconds) and a separate control unit. As battery protection, it protects the battery from dangerous deep discharge and the consumers from both undervoltage and overvoltage. It is connected between the on-board battery and the consumer and is suitable for all classic lead battery types as well as modern lithium LiFePO4 batteries. With its extremely low current consumption of less than 3 mA, it meets the strict requirements of DIN EN 13976. The device can also be used as a remote-controlled battery main switch from an external, 1-pole switch. The Battery Protector 300 has an EMERGENCY ON function, which can be used to switch the device back on at any time in an emergency. This function can also be remotely controlled using a switch. The device is equally suitable for 12 V and 24 V battery systems and has the same intelligent automatic switching thresholds or fixed, selectable switching thresholds as the Battery Protector 100. It also has a visual and acoustic pre-alarm, a separate warning switching output and two LEDs on the housing that show the operating status of the device. Alternatively, it can be used as a remote-controlled power relay ("switch unit"), e.g. on the LCD Battery Computer S, LCD Energy Monitor or VPC.

Operation as Battery Protector:

• Optical display of the operating status by two LEDs
• Acoustic alarm can be activated (when the pre-warning threshold is reached or when switched off)
• Output for external alarm display (max. 0.3 A, short-circuit proof)
• Suitable for all common lead battery types with 12 V or 24 V nominal voltage
• Suitable for lithium batteries (LiFePO4)
• Can also be used as a powerful battery main switch with protective function
• Various switching thresholds configurable
• EMERGENCY-ON function, also remote controllable

Operation as a switch unit:

• Can be used as a battery main switch
• Electronic delay prevents too fast reaction, e.g. in case of voltage drops caused by switching on heavy loads
• Optical display of the operating status by two LEDs
• Alternatively, it can be used as a remote-controlled power relay (“switch unit”)
