solid state relay
Solid State Relay (SSR) is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices; it is a kind of two terminals for input and the other two terminals for output The four-terminal device at the end uses an isolation device in the middle to achieve electrical isolation of input and output. The input terminal of the solid state relay uses a tiny control signal to directly drive a large current load.
Product Functions
Solid state relay has been widely used in computer peripheral interface system, air-conditioning, electric heating equipment, temperature control, motor control, numerical control machine, remote control systems, industrial automation device; Lights, dimmer, flasher, lighting, stage lighting control system; Instrumentation, medical equipment, copiers, automatic washing machines; Automatic fire control, security systems, as well as the grid power factor compensation of power capacitor switch, and so on

FAQ:
1) What is the difference between a moulded case current transformer and a split core current transformer?
A moulded case current transformer is a solid ring of steel in a plastic or resin case and can only be used when you fit the cable through the hole in the middle of the plastic/resin case.
A split core current transformer is manufactured with the steel core in two pieces. This enables the core to be separated, allowing you to fit the cores around the cable without disconnecting the cables. The disadvantage with split core current transformers is that they can be larger than standard moulded case and the price is approximately four times more expensive.
2) Which way round do the Current Transformers go?
The current transformers must be fitted and connected in the correct way or the meter will not be accurate. The current transformers are marked on two sides: 'P1' and 'P2.' 'P1' must face the mains side and 'P2' must face the load side. 'S1' must be connected to the main side of the meter and 'S2' to the load side. Refer to appropriate wiring diagram of the meter for correct connections.
3) Can the current transformers be a higher or lower ratio then my maximum load?
The current transformers should ideally be about 80% of the normal running load, thus allowing a 20% allowance of increasing the load in the future.
