KS53

Product catalog summary

Overview: The KS53 is a solid-state relay (SSR) designed for panel mounting with a maximum AC load capacity of 25A. It features options for round screw terminals or fasten terminals and includes a transparent finger-proof cover compliant with IP20 standards. The relay is compact, single-channel, and suitable for various applications.

Specifications:

Input Voltage: 4~32VDC
Output Voltage Options: 240VAC and 380VAC
Output Current Ratings: 10A and 25A
Dielectric Strength: 4000V
Built-in RC Snubber Circuit: Yes
Encapsulation: Epoxy resin

Application Scenarios: The KS53 SSR is primarily used in equipment such as rubber and plastics machinery, commercial kitchen appliances, instant hot water dispensers, and coffee machines.

Features:

Photoelectric isolation between input and output
TRIAC output
Removable protective cover

Selection Guide: The relay offers various configurations based on control voltage, load voltage, switching mode, load current, LED indicator, and termination type. Special attention is required for load current and ambient temperature during selection.

Precautions:

Ensure proper heat sinking for full load operation, especially above 40°C ambient temperature.
Apply thermal grease or a thermal pad for effective heat dissipation.
Tighten screw terminals within the recommended torque range (0.58~0.98N·m) to prevent damage.
Do not exceed specified limitations in the datasheet.

Characteristic Curves: The document includes curves showing the relationship between maximum load current and ambient temperature for both 10A and 25A configurations.

Panel Mount – AC Output ■ PRECAUTIONS 3. Tighten the SSR screw terminals properly. If the screws are loose, the SSR would be damaged by heat generated from connection. Also excessive screw mounting torque may damage the SSR’s internal components. The recommended mounting torque range for M3 screw is 0.58~0.98N·m. 4. Please do not use the SSR exceeding the limitation which is speciﬁed on this datasheet. ■ OUTLINE DIMENSIONS, WIRING DIAGRAMOUTLINE Outline Dimensions Quick connection type screw type Wiring Diagram Mounting Holes Control Signal Max.
