Battery Ventilator Controller

Features:-

Ventilates enclosed battery compartments, especially for lead acid batteries, to remove explosive gasses, acid fumes, excess heat and humidity.
Turns on automatically when the battery reaches its gassing voltage of 14.0 volts or higher. Use with one or two 12V box fans for rapid air exchange.
Starts a 15 minute drying cycle when the voltage drops below 13.8 volts to the float level cycle of most modern charging systems. After timeout, the blower shuts down automatically with only microamp voltage sensing load on the battery.
Manual ON control for forced ventilation when not in a charging cycle. The 15 minute drying cycle can be started manually for unattended shutdown. The controller can be mounted on the battery Compartment or at a remote location.	Optional Blowers

• The electronics package behind the panel is splash proof and sealed for the corrosive atmosphere. An LED indicator light shows when the blower is operating. A splashproof flush rocker switch selects On, Off or Automatic.

• The controller has electronic switching and when combined with a brushless blower all sparks are eliminated, allowing safe operation in the explosive battery compartment atmosphere. A self resetting electronic fuse protects against accidental wiring shorts with no maintenance or arcing. Stall detection in the blower reduces power consumption until operation can resume safely.

• Additional blowers can be added in parallel for large or multiple battery compartments up to a maximum load of 1 amp. Use a sealed 12 volt relay to switch higher loads.
