Switchmode Power Conversion Technology; Safety Features - Xantrex Truecharge TC10TB Owner's Manual

Automatic restarting of the charging sequence if 21 days has passed
since the last charging cycle has occurred. This eliminates reduced
battery capacity problems caused by normal internal battery leakage.
Automatic restarting of the charging sequence each time AC power is
reconnected.

3.2 Switchmode Power Conversion Technology

The Truecharge employs advanced high frequency switchmode power
conversion circuitry resulting in these benefits.
Much smaller size and lower weight as compared to traditional 10-amp
chargers.
Totally silent operation, without the buzz or hum traditional chargers
often generate.
High efficiency solid state circuitry, resulting in minimum heat generation.
Full charging capability even when the AC line voltage has fallen to 90
volts, where many other chargers no longer function.
Pure DC output without the current pulsations common to traditional
chargers. This results in increased battery life and eliminates the "buzz"
traditional chargers often cause on audio equipment operating from
the battery.

3.3 Safety Features

These advanced safety features come built into the Truecharge.
Isolated design. Charger output is galvanically isolated from the AC
power line to eliminate electrolysis problems on boats.
Overheat protection. The Truecharge shuts down before its internal
temperature rises to dangerous levels that may be caused by poor
ventilation or high ambient temperatures, and automatically restarts
after cooling.
Installer error protection. Output short circuit and reverse battery polarity
protected.
Protected against damage that could otherwise result from connecting
to a 24 volt battery.
