Truecharge+ Features
1–3
Selector Switches
Truecharge+ has selector switches for charge mode, battery type, and
battery temperature setting.
Charge mode The charge-mode switch allows you to select three-step charge, two-step
charge or 13.5 volt fixed output modes. Refer to Appendix B, “Battery
Charging” for an explanation of the charging algorithms.
Battery type The battery-type switch allows you to set the Truecharge+ for the
charging characteristics of flooded, AGM, and gel batteries.
Temperature The battery temperature switch allows you to set charging characteristics
based on the battery temperature. By setting the switches correctly before
you begin charging your battery, you will be ensuring that it receives the
best possible charge.
Extensive Protection Features
Truecharge+ provides the following protection features:
• Opening of the internal output fuse if a battery is accidentally
connected with reversed polarity
• Fuse opening or electronic shutdown if there is a short circuit on the
output of the Truecharge+
• Built-in protection against accidental connection to a higher battery
voltage, up to 24 VDC
• Unit shutdown if it becomes overheated because of inadequate
ventilation or a high ambient temperature
• Unit shutdown if the battery gets too hot (with battery temperature
sensor only)
Isolated Design
The DC battery charging circuits of Truecharge+ are galvanically isolated
by a transformer from the AC power circuits. This feature reduces the risk
of electric shock and helps to prevent corrosion problems in marine
applications.
