Solid State Relays (SSRs) are modern switching components and, as their name suggests, use solid state means to electrically switch on and off, rather than mechanical means. They generally have a higher switching speed than mechanical relays, as well as a longer lifespan. One of the mos popular models of Sand State Relays is the PS7801E-1A-F3-A. This article looks at its application field and working principle.

Application Field of PS7801E-1A-F3-A

The PS7801E-1A-F3-A is a single-phase SSR with zero-crossing control. It is designed for load currents up to 12A and is suitable for applications such as induction stove control, electric ovens, industrial motors, electric cookers, household appliances, industrial switching, and lighting control.

Working Principle of PS7801E-1A-F3-A

The PS7801E-1A-F3-A is a zero-crossing SSR, meaning that it is designed for use with AC power. It operates by sensing when the applied AC voltage passes through zero volts. At this point, it turns on or off based on the control signal. When a control signal such as a switch, photo diode, or thermocouple is applied, the internal opto-coupler of the SSR is activated, allowing current to flow through the relay and connect the load. This allows the load to be switched on or off quickly and without any mechanical contact, meaning it can operate for many hours or even years without maintenance.

Operating Parameters of PS7801E-1A-F3-A

The PS7801E-1A-F3-A has a variety of operating parameters that must be taken into consideration to ensure correct operation. The AC voltage range is from 85V to 265V, with an operating frequency between 47Hz to 63Hz. It has an insulation voltage of 200V, static current of 6mA, and a maximum switching capacity of up to 12A. It also features a switching time of 10ms with a minimum power off-state capacitance of 0.2uF.

Conclusion

The PS7801E-1A-F3-A is a single-phase, zero-crossing Solid State Relay with a variety of uses including induction stove control, electric ovens, and lighting control. It is a cost-effective, reliable, and long-lasting solution for switching applications. With its various operating parameters, the PS7801E-1A-F3-A can be used in a wide variety of applications.
