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-
• 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
• AC-58 — One-pole motors. These loads often have overcurrent at turn ON and overvoltage at turn OFF, so use 400VAC SSR on
• AC-53 — Three-phase motors. 2 or 3 SH zero-cross relays can drive these motors, but generally use E3P/E3PT or other three-
• 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

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 specifi ed by Teledyne.
