Precautions
Refer to the Technical Information for SSRs (Cat. No. J137) for gen-
eral precautions.
I Correct Use
Load Connection
For an AC load, use a power supply rated at 50 or 60 Hz.
The maximum operating frequency is 10 Hz.
The G3PA-(VD) has a built-in varistor for overvoltage protection.
At a low applied voltage, such as 24 VAC, the load current is not fully
supplied. When the Unit is switched ON, the voltage required to
power the Unit deprives the output signal of the necessary voltage
level and thus creates loss time. The lower the load voltage is, the
greater the loss time is. This condition, however, will not create any
serious problems.
For a DC or L load, a diode should be connected in parallel the load
to absorb the counter electromotive force of the load.
When attaching a heat sink to the G3PA-(VD), in order to facilitate
heat dissipation, apply Silicone Grease or equivalent heat conductive
grease on the heat sink. (Toshiba Silicon, Shinetsu Silicon, etc.)
Tighten the mounting screws of the heat sink with a torque of 0.78 to
0.98 N·m.
