Please note that the specifications of the control voltage, the magnitude and polarity when wiring. If the voltage is greater than the actual control of the calibration control voltage can be appropriately series resistance in the control loop, using the controller to control current to the current is greater than the minimum.

Prevent load short-circuit, so as not to burn solid state relays, operating current is greater than 5A should be equipped with suitable heat sink. Should be added between the solid-state relay and heat sink thermal grease must be in close contact.

Operating current is greater than 30A should be considered forced air cooling. The factory can supply matching the radiator.

AC solid state relay for inductive load and should take appropriate varistor as overvoltage protection (matching factory can supply). DC solid state relay for inductive load, the load should be at both ends and connected protection diodes.

The user must choose the appropriate standard models of solid state relays. Incandescent bulb for electric vehicles and other loads must consider the impact of starting current. Ambient temperature exceeds 40 ℃, it should be less than the rated current use.
