Automation Controls Catalog VDE Ideal for solar inverter compact size, 1a 35A/48A power relays HE RELAYS PV Type FEATURES • 35A/48A current at 250 V AC achieved in compact size (L: 33 × W: 38 × H: 36.3 mm L: 1.299 × W: 1.496 × H: 1.429 inch) Due to improved conduction efficiency, wide terminal blades are used. (for high capacity type) • High insulation and 10,000 V surge breakdown voltage (between contacts and coil) achieved. • Conforms to various safety standards UL/C-UL and VDE TYPICAL APPLICATIONS • Photovoltaic power generation systems (Solar inverter) RoHS compliant • Contact gap: 2.5 mm (VDE0126 compliant) Compliant with European photovoltaic standard VDE0126 Compliant with EN61810-1 2.5 kV surge breakdown voltage (between contacts) • Contributes to energy saving in devices thanks to reduced coil hold voltage Coil hold voltage can be reduced down to 40% of the nominal coil voltage (ambient temperature 20°C 68°F). This equals to operating power of approximately 310 mW. *Coil hold voltage is the coil voltage after 100 ms following application of the nominal coil voltage.
