SR203M02

Power Relays, Over 2 Amps

The SR203M02 is an industrial-grade power relay specifically designed for high-current applications where the rated current of the device exceeds 2 amps. It comes with features including a rubberized heat sink, a voltage control circuit, and a tracking protection circuit.

Application Field

The SR203M02 can be used for heavy-duty industrial applications such as powering high-power heaters, in large-scale industrial machinery, and in other higher-power operations requiring currents over 2 amps. Additionally, it is suitable for applications where high-current rating and or low operational noise or vibrations are required, such as in medical equipment, electronic instrumentation, precision instruments, and motors.

Working Principle

The SR203M02 utilizes a mechanical switch to control a load. This switch is controlled by a voltage-controlled current switch, which can be programmed to turn on and off in response to a specific voltage. When the set voltage is reached and the switch is on, the connected load will then be controlled via the switch. The tracking protection circuit allows the unit to track the voltage modulation of the connected load while the rubberized heat sink protects against overheating and improves performance.

Key Features

• Rated to sustain currents of over 2 amps
• Rubberized heat sink for improved heat dissipation
• Voltage control switch for precise control
• Tracking protection circuit for smoother operation

Conclusion

The SR203M02 is a dependable and cost-effective power relay designed to meet the needs of high-current applications. With its features such as a rubberized heat sink, voltage control switch, and tracking protection circuit, the SR203M02 is a reliable and efficient device that can handle considerable amounts of power. It is suited for a variety of applications from controlling large-scale industrial machinery to powering precision instruments and medical equipment.
