KS4

Product catalog summary

Specifications:
The KS4 Solid State Relay (SSR) is designed for industrial control applications, particularly suitable for small motor control. It features a compact size of 24.2 x 6.7 x 21.4 mm and supports a load current of 2A. The relay is available in a PCB mount Mini-SIP type with SPST-NO AC output and offers three DC input options: 5VDC, 12VDC, and 24VDC. It provides photoelectric isolation between input and output and supports two switching modes: zero-cross turn-on and random turn-on.

Procedures and Precautions:
1. Soldering should be completed within 10 seconds at 260°C or 5 seconds at 350°C.
2. Ensure proper ventilation to avoid derating the load current.
3. Correct wiring of input and output is crucial as the SSR lacks reverse polarity protection.
4. Use a varistor with a recommended voltage of 470V to prevent breakdown from transient voltage.
5. For phase modulation, ensure a time interval of over 200μs between the input pulse signal's negative edge and the line voltage zero crossing point.
6. Do not exceed the specified limitations in the datasheet.

General Specifications:
Operating temperature ranges from -30°C to 80°C, with a storage temperature range of -30°C to 100°C. The unit weight is approximately 6g, and it operates effectively in ambient humidity of 45% to 85% RH. The dielectric strength between input and output is 2500VAC, and the insulation resistance is 1000MΩ at 500VDC.

Application Scenarios:
The KS4 SSR is widely used in household appliances, medical devices, communication equipment, and more.

Characteristic Curves:
The document includes graphs showing the relationship between maximum load current and ambient temperature, as well as peak surge current versus continuance time.

The SSR’s case serves to dissipate the heat generated by the SSR itself. If poor ventilation is unavoidable, the load current must be derated. Please refer to the curve of Max. Load Current vs. Ambient Temperature for derating. 3. The internal input circuit of SSR does not have the reverse polarity protection, thus make sure the wiring of input and output and the input polarity is correct so as to avoid any...
