REVO SSR Solid State Relay is suitable for resistive loadsCurrent range depend by the heatsink and ambient temperature. The rating included in the code number is the teoretical range of the junction, to understand the max current allowed you need to calculate it on the graph.Range: 0:62; 0:74; 0:90Supply voltage up to 480V or 600Vac as optionFully isolated from the powerZero crossing firing mode (ZC).Logic input signal 4 to 30Vdc typical (SSR).Constant current drain, independent of supply voltage with SSR inputIntegrated Fuse and Fuse Holder with SR1 Size.Load type: ResistanceIP20 protectionComplies with CE, EAC and cUL (pending).An Heatsink is necessary for the correct work of the units, CD Automation offer a wide range of heatsink to allow you to customize your unit.Heatsink are sold separately and are not included with this ordering code
