A large range of heat sinks is available. For heat-sink mounting, use thermal grease or a thermal pad with high conductibility specified by Teledyne. See our website for additional heat sinks. Thermal Pad Teledyne P/ n –12 Typical Loads (Random) HIPpak relays with random turn-on are designed for high inductive loads or phase angle control applications. Our data sheet lists nominal current of power thyristors corresponding to a resistive load (AC-51). Depending on the loads, check the inrush current at turn ON and possible overvoltages at turn OFF. Main applications: • —AC-55b Incandescentor infraredlamps.Inrushcurrentis generally10 timesIn duringfew10ms.Randomrelaysoftenuse in-phaseanglecontrollersor soft-starterswiththe right control. • —Three-phase AC-53 motors.2 or 3 randomturn-onrelayscan drivesuchmotors. • —AC-56a Transformerloads.Very highinrushcurrentupto 100 timesIn. Use a randomturn-onSSR liketheSH. The table below lists recommended current values for proper lifetime expectancy. Typical Loads (Zero-Cross) HIPpak relays with zero-cross turn-on are designed for most types of loads. Our data sheet lists the AC-51 current value corresponding to resistive loads. For other loads, check the inrush current at turn ON and possible overvoltages at turn OFF: • —AC-55b Incandescentlamps.Inrushcurrentis generally10 timesIn duringfew10ms. • —AC-55a Electricdischargelamp.These loadsoftenhaveovercurrent at turnON andovervoltage at turnOFF, so use 400VACSSR on 230VACmains. • — One-pole AC-58 motors.These loadsoftenhaveovercurrent at turnON andovervoltage at turnOFF, so use 400VACSSR on 230VACmainsandadapttheSSR currentto the starting current of the motor. • —Three-phase AC-53 motors.2 or 3 SH zero-crossrelayscan drivethesemotors,butgenerallyuse E3P/E3PT or otherthree-phaserelaysor SH randomrange. • —AC-56a Transformerloads.Very highinrushcurrentupto 100 timesIn. Use SH randomrelayor peakcontrolSSR. • —AC-56b Capacitorloadswithveryhighcurrentat turnON andovervoltage at turnOFF. Ourhigh-voltage relaysare welladaptedforhighinrushcurrent.
