Why Choose Rogue’s 12V/30Amp LVD?

Bene ts

• Easy to install

• Control up to 360 Watt load directly or add a separate relay to control

even larger Loads

• 7 position selector switch makes it easy to choose the shut-o
voltage or “always on” LVD override

• Disconnect voltage selections range from 9.5V to 11.5V

• Low voltage LV Alert output

• Uses a 30 Amp automotive style fuse for protection and easy

replacement

Applications

• Idle reduction for work vehicles

• O -grid solar installations

• Recreational vehicles

• And many other battery-powered installations

Features

• Supports all 12V lead acid batteries

• Conformal coated and potted for humid conditions

• Disconnect voltages are every 0.5V from 9.5V to 11.5V

• Approximate 10 second delay before disconnect

• Self-consumption (Typical): LVD unit “ON” or set an LVD threshold: 8

milliamps (mA) and LVD unit set to “OFF”: 800 microamps (uA)

Installation Instructions

• Connect 12V Battery and 12V Load as shown in the illustration above.

• Connect black ground wire to system’s common ground.

• Turn knob to selected disconnect voltage or to “ON” for continuous

operation or “OFF”.

• Power to the load will be disconnected when battery voltage reaches
selected voltage and

will reconnect when the battery is charged

1 Volt higher than selected voltage.

• If Load does not receive power when connected to a good battery, check
the fuse.

• If used, connect the orange LV Alert wire to relay or other control
equipment. When battery is low, LV Alert outputs battery voltage at
300mA max.

Note: Under no circumstances should a fuse over 30 Amps be used with this
device.
