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
SCH 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 threephase 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.
Protection
• To protect the SSR against a short-circuit of the load, use a fuse with a I2t value = 1/2 I2t value specified.
EMC
Immunity:
• Our data sheets list the immunity level of our SSRs according to the main standards for these of products: IEC/EN61000-4-4 and
IEC/EN61000-4-5. You can compare the high immunity level with other products on the market.
Emission:
• Teledyne SSRs are designed in compliance with standards for class A equipment (Industry).
• Use of this product in domestic environments may cause radio interference. In this case the user may be required to employ
additional devices to reduce noise. SSRs are complex devices that must be interconnected with other equipment (loads, cables,
etc.) to form a system. Because the other equipment or interconnections may not be under Teledyne’s control, it shall be the
responsibility of the system integrator to ensure that systems containing SSRs comply with the requirement of any rules and
regulations applicable at the system level.
• The very low zero-cross voltage of SCH relays (<12 volts) improved the conducted emission level in comparison with most SSRs
on the market with zero-cross voltage often higher than 50 volts.
