Notes while using
- Allow for different margins in current rating based on the nature of the load. (For resistive loads, choose 2-3 times the load current. For inductive or capacitive loads, choose 3-4 times the load current.)
- The actual load current is greatly influenced by the ambient temperature. When the ambient temperature is high or the heat dissipation conditions are poor, increase the current capacity. To prevent short circuits in the load circuit during use, overload protection should be added. For specifications above 600V, GZ20SL/GZ20CSL current-protected solid-state relays can be used as an option.
- To prevent the generation of inductive counter electromotive force due to long output power lines, overvoltage protectors should be connected in parallel at the output end to protect the solid-state switch from damage during overvoltage. The selection of metal oxide varistors (MOV): choose a value of 80% of the rated voltage of the solid-state relay.
- The contact surface between the matching heat sink and this product must be flat and smooth. Apply a layer of thermal conductive silicone grease on the surface. When fixing it, tighten the screws symmetrically with spring washers and flat washers to prevent loosening due to thermal expansion and contraction of the screws.
- Ensure that the screws are properly tightened to prevent loosening due to thermal expansion and contraction.
Product Details
- Optical-magnetic isolation between input and output circuits.
- Light Emitting Diode (LED) indicates the working status.
- The output end consists of two sets of normally open, contactless bidirectional DC solid-state switches.
- Output is non-polarized, compatible with both AC and DC power supplies, and easy to install.
- The GZ20SL/GZ20CSL model features automatic protection against overcurrent and short circuits.
- Utilizes solid encapsulation for corrosion and shock resistance, ensuring stable and reliable operation. The product is used as a charging and discharging switch for electric vehicles or battery power supplies.
