PRECAUTIONS

1)

Whenchoosing a Solid State Relay (SSR), note the actual loadcurrent and ambient temperature and reference the Characteristic Curves below.

2)

SSRs require a adequate heat sinking or other effective cooling measures.

3)

With ambient temperature above 25°C refer to the curve of Max. Load Current vs Ambient Temperature for load current derating.

4)

Apply heat-conductingsilicon grease orathermal transfer padonthe space between SSR andheatsink and screw the SCR firmly in to the heat sink to

avoid damage from overheating.

5)

Tighten theSSR terminal screws properly. We recommended screw installation torque asfollows :

M4 screw mounting torque range is (0.98-1.37)N • m,

M3screw mounting torque range is (0.56-0.98)N • m.

Lose screwswill damage the SSR with heat generated from connections.Also, excessive screw torquemaydamagerelays internal components.

6)

It is recommended to use a heat sink matched to the Current Load. With any heat sink test that the SSR basetemperature does not exceed 65"C.

7)

When using the PCS15 relay with an inductive load, it is suggested to select random tum-on (i.e.,a model with "R” letter).

8)

The PCS15 is not suitable for capacitive loads; if you must then do not choose products with varistor protection(i.e., a model with “Y” letter).

9)

Listed parameters are based on resistive loads. Do not use the relay beyond the described current, temperature, load or voltage limits as de-

scribed in this data sheet.
