Truecharge+ is an advanced battery charger designed specifically for high performance, deep-cycle lead-acid batteries. It is smaller and lighter than many other chargers and can be installed or stored in small compartments. It has AC to DC isolation, a surge protector, and many other safety features which reduce potential shock and fire hazards.
Features:
20 Amp Continuous Rating: Truecharge 20+ delivers a 20 amp charging current. The chargers only reduce the charging current below these rated levels when the battery is approaching full charge or when there may be overheating in high ambient temperatures. Because it delivers rated current over most of the charge cycle, Truecharge+ charges your batteries faster than many other chargers with a higher rating.
Simultaneous Three-Battery Bank Charging: Truecharge+ has three separate DC positive terminals to allow charging of three separate batteries (or battery banks). The total current into the batteries is a maximum of either 20 amperes or 40 amperes, depending on the model, which is divided amongst the batteries according to their state of discharge.
Wide Voltage Range Operation: Truecharge+ maintains the correct charging voltage for your battery when the AC line voltage drops as low as 90 VAC, or rises as high as 135 VAC. A surge protector in Truecharge+ protects it from surges and spikes on the AC power line.
Selector Switches: Truecharge+ has selector switches for charge mode, battery type, and battery temperature setting.
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.
Fixed Voltage Mode: The fixed voltage mode setting is meant to be used as a power supply or battery eliminator. It is not meant for charging batteries. The battery type, battery temperature, and equalize switches are all ignored in fixed voltage mode. The remote battery temperature sensor does not compensate for the voltage, but the battery over-temperature shutdown is still active.
