Mounting
Most SSRs must be mounted on heat sinks. 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.

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
