Notes while using

Since the load voltage of a DC solid-state relay is equal to its off-state voltage, and the load current is at its maximum value at room temperature, a margin should be left when selecting one. For resistive loads: the current should be chosen at 2.5 to 4 times the load current, and the voltage should be chosen at 2 to 3 times the load voltage. For inductive loads: the current should be chosen at 4 to 6 times the load current.


The actual load current is greatly related to the ambient temperature. When the ambient temperature is high or the cooling conditions are poor, the current capacity should be increased. To prevent a load short circuit during use, it is required to add an overload protector in the load circuit.


For inductive loads, the GDZ08GY/GDZ08CGY model must have a flyback diode connected across both ends of the load to prevent damage to the solid-state switch by over-voltage. The GDZ08GD/GDZ08CGD model has an integrated flyback diode, so it can be used directly with inductive loads without adding a separate flyback diode.


The heat sink that comes with this product must have a flat and clean contact surface, and a layer of thermal conductive silicone grease should be applied to its surface. When fixing, screws should be tightened symmetrically with spring washers and flat washers to prevent loosening due to thermal expansion and contraction.
