9 basic knowledge of single-phase solid state relay

Single-phase solid state relays have a wide range of applications, and you can use the basic knowledge to understand them. Do you know the following?

1. Single-phase solid state relays can be divided into DC-controlled DC solid-state relays, DC-controlled AC solid-state relays and AC-controlled AC solid-state relays

2. The single-phase solid state relay has no moving parts, no mechanical wear, no action noise, no mechanical failure, and high reliability;

3. Single-phase solid state relays have no arcing contacts, no sparks or arcs between contacts, no contact jitter and wear, and little external interference;

4. Single-phase solid state relays have rapid switching speed, and the action time can reach 10-3S or less;

5. Single-phase solid state relays have high sensitivity, low control power, and are well compatible with TTL and CMOS circuits;

6. The single-phase solid state relay has excellent shock and vibration resistance, and realizes "zero" voltage switching;

7. Single-phase solid state relays are potted with insulating resin, which has moisture-proof, mildew-proof, anti-corrosion properties, and good explosion-proof performance;

8. Single-phase solid-state relay switches work fast and have a long life;

9. Single-phase solid state relays are easy to realize additional functions.
