ARCO Zeus A275L High Output Dynamo
The ARCO Zeus A275L is a powerful 12V high-output alternator, developed for onboard systems with a high energy demand. Thanks to its high charging capacity, even at low revs, you can charge large lithium and lead-acid battery banks significantly faster and limit the number of engine operating hours required.
The A275L is designed to deliver high charging currents for extended periods. The combination of dual internal fans, an externally positioned rectifier and a heat-dissipating Cerakote coating ensures excellent cooling and high continuous performance.
With a maximum output of over 300A and a maintain charging current up to 227A at cruising speed is the A275L an interesting alternative to a separate onboard generator?.
For safely and correctly regulating the charging current, a external dynamo controller necessary, such as the ARCO Zeus Bluetooth Controller. This allows the charging process to be precisely tailored to lithium and other battery types, and monitors voltage, current and temperature, among other things.
