USINA 120A Smart Connect

The USINA 120A Smart Connect is a high-performance power supply and smart battery charger designed for demanding 12-volt power applications. With an output current of up to 120 amps and a maximum output power of 1,500 watts, it is particularly well-suited for high-performance car audio systems, show cars, competition vehicles, and for charging and maintaining battery banks.

The output voltage can be adjusted within the range of 12 to 16 volts DC. This allows the Smart Connect to be used both to power connected 12-volt components and to charge various battery systems. The built-in Smart Charger Plus monitors the charging process and adjusts the charge accordingly.

A key feature of the Smart Connect series is its support for an external digital control unit. This unit allows you to conveniently monitor settings, charging parameters, and operating information. The external control unit is sold separately.

The backlit display allows you to monitor key operating parameters directly. In voltmeter mode, the battery voltage can be displayed even when the power supply is disconnected from the mains. In addition to the current voltage, you can also monitor the minimum and maximum values recorded.

Various smart charging functions are available for different applications. These include an automatic and a customizable slow-charging mode, programmable charging times, a recovery function, and a special lithium mode.

The temperature-sensitive Smart Cooler fan control activates cooling only when necessary. This reduces noise and unnecessary fan runtime while simultaneously controlling the thermal load on the components.

Notes on Performance Specifications

• The manufacturer determined the 120 A output current rating using an ohmic load.

• The actual output power that can be achieved may vary depending on the line voltage and operating conditions.

• When used with lithium batteries, the charging voltage and charging parameters must always be adjusted to match the specifications of the battery or BMS being used.

• The external Smart Connect Digital Control Unit is not included as standard and is sold separately
