The Phoenix 24/25 (1 + 1) ip43 smart charger from vitron Energy (mpn psc242551085) is a powerful state-of-the-art battery charger. The device is designed for 24v battery voltage and offers in addition to the powerful main charging output 25a also a secondary charging output with a charging power of 3a for a starting battery

With the built-in Bluetooth module, the Phoenix 24/25 (1 + 1) ip43 smart charger fits in with Vitron's ever-growing Smart family, which can be perfectly networked and also centrally controlled via various channels. In addition to the Bluetooth module, there is also a vE.Direct connection and a freely programmable relay. Optionally, the Smart Battery Sense can also be connected to control the battery temperature compensation. The proven five-step charging algorithm and the ability to program your own charging algorithm make the Phoenix Smart Charger 24/25 (1 + 1) ip43 a universal high-tech battery charger that can optimally charge almost any type of battery.

Bluetooth Smart enabled
Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, change settings, and update the charger when new software features become available.

Two outputs for charging 2 batteries
The second output, limited to about 3A and with a slightly lower output voltage, is intended to charge a boot battery.

Customizable 5-step charging algorithm: mass absorption-repair-floating storage-storage
The Phoenix Smart Charger features our well-known "adaptive" battery management system that can be pre-configured to suit different types of batteries. The "customizable" function will automatically optimize the charging process in relation to how the battery is used.

BatterySafe function. Prevention of damage due to excessive gas:  
If, for fast charging of a battery, a high charging current is selected in combination with a high suction voltage, the charger will prevent damage due to excessive gas ejection by automatically limiting the rate of voltage rise as soon as the gas voltage is reached.

It also charges Li-ion (LiFePO4) O batteries
Charger on-off control can be applied by connecting a relay or an open collector optical couple output from a Li-ion BMS at the remote on-off port.
Alternatively, complete control of voltage and current can be achieved with Bluetooth.
