Load Manager 2

The Load Manager 2 is a compact load management controller designed to automatically shed up to two electrical loads when low-voltage conditions are detected. This device is specifically tailored for use in fire apparatus, ambulances, rescue vehicles, command vehicles, and other specialty vehicles that require reliable electrical systems. The Load Manager 2 helps reduce electrical demand and protect battery system performance by sequentially controlling non-critical electrical loads as system voltage decreases. Its ability to manage multiple loads makes it an essential component in ensuring the continued operation of critical vehicle systems during low-voltage situations.

The Load Manager 2 continuously monitors the vehicle's 12 VDC electrical system, providing real-time feedback on system voltage levels. When system voltage drops below the preset threshold, the first relay operates to control or disconnect the first load. If voltage drops an additional 0.5 volts, the second relay operates to manage the second load. Both relays provide normally open and normally closed 30-amp contacts, allowing for flexible integration with a variety of vehicle electrical circuits. The voltage set point is field adjustable from 10.5 to 13 VDC, with a standard set point of 11.5 volts. This flexibility ensures that the Load Manager 2 can be adapted to different vehicle systems and operational conditions.

When system voltage rises to an acceptable level, the Load Manager 2 automatically resets and restores normal operation, ensuring continuous and reliable electrical performance. The device's automatic reset feature is a key aspect of its design, as it minimizes downtime and ensures that critical systems remain functional even during low-voltage events. The Load Manager 2 is built with heavy-duty components to ensure durability and reliability in demanding environments. Its compact design simplifies installation in emergency and specialty vehicles, making it an ideal solution for a wide range of applications including fire apparatus, ambulances, rescue vehicles, and command vehicles.
