Question:

What is the maximum allowable maximum current for a solid-state relay?

What is the maximum allowable maximum current for a solid-state relay?

Answer:

Solid-state relay secondary side generally optocoupler isolation primary, voltage control, only the maximum allowable voltage at all, generally 32VDC, the current consumption will not exceed 15mA. Solid State Relay: Solid State Relay (SSR), which is a non-contact switch consisting of microelectronic circuits, discrete electronic devices, and power electronic power devices. It is a two terminal for the input and the other two End for the output of the four-terminal device, the middle of the isolation device to achieve the input and output of the electrical isolation. Solid-state relay input with a small control signal to achieve direct drive high current load.

Solid-state relay secondary side generally optocoupler isolation primary, voltage control, only the maximum allowable voltage at all, generally 32VDC, the current consumption will not exceed 15mA. If it is a side of the output current, according to the use of thyristor capacity and cooling different, the current maximum size I have seen single-phase 600A 380V, but not actually used.

If the 32V solid state relay control circuit in series with a 32V lamp, light and solid state relay can work properly? To answer Do you want to judge whether the solid state is burned? General solid can work high level range is 8-32V, in order to reliable work at least should ensure that the drive voltage above 12V. Then if the demon king loop inside the string lights, then there are two points to note: 1, if it is a direct string of LED, LED light pressure drop is very low, little impact on the drive solid state. But it should be noted that, to choose a little more resistance to the current LED, in general, this one can be met. 2, if you string into the counter with the kind of 16,22 specifications of the 24V drive LED indicator, because of this indicator light inside the limited current resistance, so this time need to consider the indicator of the partial pressure problem, there May be too large pressure, resulting in solid can not work reliably.
