This relay is designed for use

in applications in which it is

exposed to high surge condi-

tions. Care must be taken to

ensure proper heatsinking

when the relay is to be used at

high sustained currents. Ade-

quate electrical connection

between relay terminals and

cable must be ensured.

Thermal characteristics

The thermal design of Solid

State Relays is very important.

Compare the value found in the load current versus tempera-

ture chart with the standard heatsink values and select the

heatsink with the next lower value.

It is essential that the user

makes sure that cooling is ad-

equate and that the maximum

junction temperature of the

relay is not exceeded.

If the heatsink is placed in a

small closed room, contr ol panel

or the like, the power dissipation

can cause the ambient tem-

perature to rise. The heatsink

is to be calculated on the basis

of the ambient temperature and

the increase in temperatur e.
