New Type SSR KRE Product Introduction
KRE is a 3 phase intelligent voltage regulation module with integrated heat sink. This product adopts a unique software programming method to make the power regulation have excellent linearity; This product has SCR fault detection function, load circuit disconnection detection function, phase-lack detection function and multipole adjustable temperature protection function. When the product detects a fault, it will cut off the output and send a fault signal to the upper computer; When the fault is eliminated, the module can resume operation by itself. It is widely used in the load control of various industrial equipment, such as 3 phase heating rods.

Product Special Function Introduction.
Over-temperature Protection | When the product is working, the temperature of the product is monitored in real time. When the set temperature value is exceeded by 100 ℃ (typical value), the output of the product will be cut off. At the same time, the fault indicator light is on and the output is normally open and the alarm contacts (NO, COM) are closed. It is necessary to wait for the temperature of the product to drop below the set value of 60 ℃ (typical value) before the product can return to normal working state on its own. |
SCR Fault Detection | When the product is not connected, if the SCR short circuit is found, the product will cut off the output, at the same time, the fault indicator light is on and the output is normally open and the alarm contact (NO, COM) is closed. |
Load Disconnection Detection | When SSR is not connected, if load disconnection is found, SSR output will be cut off. At the same time, the fault indicator will be lighted and the output of the alarm contacts (NO, COM) will be closed. |
Phase-lack Detection | When the phase-lack failure happens in 3 phase voltage, the relay will automatically cut off the output with the fault indicator lighted and the output of the alarm contacts (NO, COM) will be closed. |
