PRECAUTIONS

DIMENSIONS (mm)

1.

Maximum Soldering Temperatures: 260°C for a maximum of 10 seconds or 350°C for a maximum of 5 seconds.

2.

The SSR case serves to dissipate heat. Install the relays so that they are adequately ventilated. If poor ventilation is unavoidable, the load current must be

reduced. Please refer to the curve of "Max. Load current Vs. Ambient Temperature".

3.

The input circuitry does not incorporate a circuit protecting the SSR from being damaged due to a reversed connection. Make sure that the polarity and the

input and output are correct when connecting.

4.

If the output transient voltage exceeds the nominal value a varistor should be mounted on the SSR output terminals in parallel to prevent a breakdown of

the triac output junction. The result could be a permanent short of the output. The recommended varistor voltage 470V.

5.

When using the relay in phase control applications, at a phase control angle close to 180 degrees the relay's input signal will turn off at the trailing edge of

the AC sine wave. The phase delay must be limited to end 200us before AC zero cross. This assures that the relay has time to switch off. Shorter times

may cause loss of control at the following half cycle.
