EVO-AT Series Battery Charger

The “EVO” Series battery charger is a SCR-based float battery charger for stationary/utility applications. Its next-generation design incorporates all the quality and reliability of the original AT charger series and offers a built-in health and diagnostics system (patent-pending).

• The EVO is designed to help with compliance to NERC PRC-005 standards and other utility industry requirements.
• The charger’s open architecture design allows for flexible operation including user-configured alarm relays and field-upgradable firmware.
• Its built-in health system continuously runs self-diagnostics to provide status notifications, alerting you of any issues in real-time.
• Pressing the Health button initiates a system diagnosis of all parameters and components to verify that the charger is operating properly.
