Harmony Relay. Semiconductor relay for mounting on a heat sink or mounting plate. The low internal voltage drop reduces power loss heat. The factory-mounted thermal conductive film allows for direct and clean installation without the use of thermal paste. The internal diagnostics enable monitoring of the load circuit for wire breakage, short circuit, or missing mains voltage and switching function of the semiconductor, which is indicated via LED display and fault signal output. A button allows for testing the switching output. Switching voltage 24-300 VAC. Current 25 A. Phases 1. Zero voltage switching behavior. Control voltage 3-32 VDC. LED display. Dimensions 45x59x44 mm. Design Hockey Puck. Terminals with telescopic screws facilitate the connection of wires with ring terminals and cable lugs. Special feature: pre-mounted thermal conductive film, diagnostic function of the switching output with diagnostic output and button for testing. A thermal analysis must be conducted for the selection of a separate heat sink.
