ARCO Zeus A225S High Output Dynamo<\/strong><\/p>\n

The ARCO Zeus A225S<\/strong> is a powerful and compact 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 considerably faster and limit the number of engine running hours required.<\/p>\n

The A225S is designed to deliver high charging currents for extended periods. The combination of dual internal fans, an externally positioned rectifier and a heat-dissipating coating ensures excellent cooling and high continuous performance.<\/p>\n

With a maximum output of 254A<\/strong> and a continue charging current to 187A<\/strong> is the A225S an interesting alternative to a separate onboard generator.<\/p>\n

Even at lower engine speeds, the charging output remains high. At 3,000 alternator rpm, the warm A225S still delivers approximately 157A<\/strong>. With a standard pulley ratio of approximately 1:2, this corresponds to roughly 1,500 rpm engine speed<\/strong>. The exact ratio may vary depending on the motor and pulley configuration.<\/p>\n

For safely and correctly regulating the charging current, a external dynamo controller necessary<\/strong>, such as the ARCO Zeus of Omega Bluetooth Controller<\/strong>. This allows the charging process to be precisely tailored to lithium and other battery types, and monitors voltage, current and temperature, among other things.<\/p>\n
