Relays RSS Series

At higher voltages, the current will be
correspondingly higher.

Recommended Loads

Lamp Loads

Transformer Loads

Transformer loads sometimes result in severe inrush current when the trans­former saturates during the first cycle. Use a relay rated for this surge, which
has a 1/2 cycle surge current greater than the maximum applied line voltage ÷
the transformer’s primary resistance (approximately 10x rated current).

Heater Loads

When using solid state relays for driving heaters where the load is switched
on and off rapidly and continuously, severe thermal stress will result. In such
cases, use an SSR relay at no more than 75% of the rating.

Zero voltage switching is ideal for driving incandescent lamps,

Calculating Input Current

RSS relays (DC in/AC out) have a circuit with 1,000Ω in series

with opto-couplers LEDs. At 4V input, the relay will turn on with

3mA: [4V – (1V drop across LED) = 3V]; [3V ÷ 1,000Ω = 3mA].

[(Input Voltage – 1) ÷ Impedance] = Input Current (A)

Technical Notes

Environment

Do not install SSRs near sources of excessive heat. Make sure applications are dry and well ventilated.

If SSRs must be installed in an environment subject to high temperatures or poor ventilation, or if SSRs are mounted collectively, reduce the load current so that it
does not approach the ambient temperature-load current recommendation. (See the Temperature Derating Curves on the following page.)

When SSRs are used with inductive loads, suppress the inrush current to half of the peak surge current.

Heat Sinks

Heat sinks are recommended for 10, 25, 50, 75, and 90 amp rated solid state relays depending on ambient temperature and mounting position. The recommended
heat sink dimensions and material are shown in the table:

Output Rating Dimensions Material

10A 12" x 12" x 1/8" Aluminum (black anodized)

25A 12" x 12" x 1/8" (DC/AC) Aluminum (black anodized)

25A 15" x 15" x 1/8" (AC/AC) Aluminum (black anodized)

50A 15" x 15" x 1/8" Aluminum (black anodized)

75A 17" x 17" x 1/8" Aluminum (black anodized)

90A 17" x 17" x 1/8" Aluminum (black anodized)

Using a thermal compound between the base of the SSR and the heat sink for heat dissipation is recommended.

Wiring

Locate SSRs as far from motor leads as possible to prevent malfunction from induced current.

Use shielded wires for input leads when they are exposed to a source of induced current.

Mounting

Provide sufficient ventilation.

Use #6 – 32 screws, flat washers, and lock washers to secure mounting on heat sinks.

Vertical mounting is recommended to allow air to flow unimpeded. Horizontal or inverted mounting is possible, but the SSR must be derated according to the der­ating curves on the following page.

Additional Information

Do not exceed the load voltage and current specifications.

A small-capacity load may not turn off due to the leackage current present after the SSR has turned off. If this is the case, use a resistor in parallel with the load
to shunt the leakage current.

Observe the polarity of input terminals. Failure to do so may cause damage to the SSR.

When the SSR output is subjected to a higher than rated voltage, a varistor or other element should be connected to the output terminals to absorb the over-volt­age.

When the input signal contains a ripple voltage, the lowest ripple amplitude should exceed the minimum pick-up voltage of 4V.
