Select option using the dropdown box above. Fear not, because the Cristec Isolators have a special isolated excitation 'IG' terminal, which, when conected to the ignition switch power, feeds current-regulated power to the B+ terminal on these types of alternators for the initial excitement and power-up.Ĭristec Isolators are available in 100A, 150A and 200A, with 2 or 3 outputs. Some modern automotive type alternators have an micro-processor controlled internal voltage regulator which requires a minimum of 8VDC at start up in order to power-up and function properly.

With a voltage drop of less than 0.05V, Cristec Isolators dissipate 30x less wattage in the form of heat than traditional diode designs (due to voltage drop).

Smart battery isolator vs traditional battery isolator series#

The Cristec RCE Series uses MOSFET (MOS Field-Effect Transistors), which don't have a voltage drop like diodes do. Most battery isolators use diode splitters, and therefore suffer from an unwanted voltage drop. This Isolator also has an automatic voltage sensing function, so can work with 12VDC or 24VDC systems. This smart FET-based isolator always charges the lowest bank first, and keeps managing the batteries until they are all charged.

This isolator replaces the battery switch, and does the switching automatically, so you never have fiddle with a switch, or worry about which battery is charging. These Cristec electronic battery isolators allow multiple banks of 12V batteries (or 24V batteries) to be automatically tied together for charging, but then will automatically prevent the current from flowing from one battery bank to another.
