AVO Intros Multi-Amp SR-98 Relay Test Set

AVO International (Dallas) introduced the Multi-Amp SR-98 Relay Test Set, a universal relay test system. The SR-98 performs at 115A at 920VA, allowing for testing high burden relays requiring more than 700VA output. The unit provides phase shift capability of 0 to 359.9 degrees between the main ac current and auxiliary ac voltage outputs, or between the 230V output terminal on the main ac current and the auxiliary ac voltage outputs. The SR-98 is designed to test all electromechanical, solid-state and microprocessor-based overcurrent relays including voltage controlled, voltage restraint and directional.
