Parameters

---

● Rated current: 200A,250A,300A,400A

● Rated voltage: Three phase 380VAC (three-phase three-wire)

● Control signal: 4-20mA,0-5VDC,0-10VDC

● Control frequency: 50Hz/60Hz

● Output mode: phase output

● Protection function: Over temperature protection

● Operating environment: Ambient temperature below 45 °C, ambient humidity below 90% RH

Notice

---

● The input circuit of the main circuit adopts three-phase three-wire connection, no phase sequence requirement.

● SCR is a high current component, so please be sure to tighten the (R, S, T) and (U, V, W) terminals, otherwise it will heat up the terminals and then burn out the SCR.

● If the load adopts Y-connection, the neutral point cannot be connected to the neutral line, otherwise the SCR will lose control.

● When the heat sink temperature exceeds 75 °C, the over-temperature protection will be automatically turned on and stop the module from working. At this time, only the power status LED is lit.
