The Orion Tr-Smart DC-DC from Victron Energy (MPN ORI242440140) is a professional, DC to DC adaptive 3-stage charger with integrated Bluetooth, known on the market as a battery-to-battery (B2B) charger. The charge booster is suitable for use in dual battery systems in vehicles or on boats where the alternator and the starter battery are used to charge the service battery. The charger can be used in 12V or 24V systems and is suitable for both lead-acid and lithium batteries. Models up to 400W are available and an unlimited number of units can be connected in parallel to increase the output power.

Key features

• Suitable for Bluetooth Smart
• Fully programmable
• Adaptive 3-stage charging algorithm
• Remote on/off
• Short-circuit proof
• Parallel connection possible to increase the output current
• Overtemperature protection
• Protection class IP43

Suitable for Bluetooth Smart

Monitoring, changing settings and updating the charger with newly available software functions can be carried out with any Bluetooth-enabled smartphone, tablet or other device.

Adaptive 3-stage charging algorithm: constant current - constant voltage - conservation

• With lead batteries, it is important that the charging time is kept short during shallow discharges in order to avoid overcharging the battery. After a deep discharge, the constant voltage period is automatically extended to ensure that the battery is fully charged.
• For lithium batteries, the recording time is fixed, with a default setting of 2 hours.
• Alternatively, a fixed output voltage can be selected.

Remote on/off

A remote on/off switch or a relay contact can be connected to the two-pin connector. Alternatively, connection H (right) of the two-pin plug can be connected to a positive battery terminal or connection L (left) of the two-pin plug can be connected to the negative battery terminal (or to the body of a vehicle, for example).
