High Industrial Performance (HIPpak) Solid-State Relays
Mounting
HIPpak 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.

Typical Loads (Random)
SH 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 — Incandescent or infrared lamps. Inrush current is generally 10 times In during few 10ms. Random relays often use in-
phase angle controllers or soft-starters with the right control.
AC-53 — Three-phase motors. 2 or 3 random turn-on relays can drive such motors.
AC-56a — Transformer loads. Very high inrush current up to 100 times In. Use a random turn-on SSR like the SH.
The table below lists recommended current values for proper lifetime expectancy.

Typical Loads (Zero-Cross)
SH 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 — Incandescent lamps. Inrush current is generally 10 times In during few 10ms.
AC-55a — Electric discharge lamp. These loads often have overcurrent at turn ON and overvoltage at turn OFF, so use 400VAC
SSR on 230VAC mains.
AC-58 — One-pole motors. These loads often have overcurrent at turn ON and overvoltage at turn OFF, so use 400VAC SSR on
230VAC mains and adapt the SSR current to the starting current of the motor.
AC-53 — Three-phase motors. 2 or 3 SH zero-cross relays can drive these motors, but generally use E3P/E3PT or other three-
phase relays or SH random range.
AC-56a — Transformer loads. Very high inrush current up to 100 times In. Use SH random relay or peak control SSR.
AC-56b — Capacitor loads with very high current at turn ON and overvoltage at turn OFF. Our high-voltage relays are well adapted
for high inrush current.
