For over voltage protection, a Varistor may be used.
A varistor used for the above mentioned scenarios should be located as close to the main output triac as
possible.
Particular attention needs to be paid when utilizing SSRs that incorporate zero crossing circuitry.
If the phase difference between the voltage and the current at the output pins is large enough, zero crossing
type SSRs cannot be used. The result, if zero crossing SSRs are used under this condition, is that the SSR
may not turn on and off irregardless of the input current. In this case, only a non zero cross type SSR should
be used in combination with the above mentioned snubber circuit selection process.
The load current should be within the bounds of derating curve. (Refer to Fig.2)
Also, please use the optional heat sink when necessary.
In case the optional heat sink is used and the isolation voltage between the device and the optional heat sink
is needed, please locate the insulation sheet between the device and the heat sink.
When the optional heat sink is equipped, please set up the M3 screw-fastening torque at 0.3 to 0.5N･m.
In order to dissipate the heat generated from the inside of device effectively, please follow the below sugges-
tions.
(a) Make sure there are no warps or bumps on the heat sink, insulation sheet and device surface.
(b) Make sure there are no metal dusts or burrs attached onto the heat sink, insulation sheet and device sur-
(c) Make sure silicone grease is evenly spread out on the heat sink, insulation sheet and device surface.
Silicone grease to be used is as follows;
1) There is no aged deterioration within the operating temperature ranges.
2) Base oil of grease is hardly separated and is hardly permeated in the device.
3) Even if base oil is separated and permeated in the device, it should not degrade the function of a device.
