Overview
The Cristec Voltage Guard unit is a very useful tool for managing the potential for accidental deep discharge of service batteries on DC systems.
On simple systems it may be enough to manually turn off consumer groups or even consumers individually but on larger vessels the potential to lose a lot of battery power without noticing is greater and some form of automation is helpful.
Consider these devices as automatic load-shedding relays. If a number of them were used in a system, they can even be configured to disconnect loads at varying levels of battery discharge to a point where only critical navigation and communication units remain connected.
