Summary

The ADDFK series capacitor switching switch adopts high-speed 32 bit CPU precise control to close and open the capacitor specific magnetic holding relay. Realize the capacitor's zero crossing voltage and zero crossing current switching, with no surge current switching and no arc pulling during switching. The magnetic holding relay has the advantage of zero power consumption during normal operation, with extremely low overall power consumption. The starting power consumption is less than 10% of the same capacity AC contactor, making it a replacement for AC contactors.

Functional characteristics

☆ Equipped with a DC negative 12V voltage signal control interface

☆ Equipped with automatic networking function with dedicated 32 loop controllers

☆ Protection functions such as phase loss protection, automatic disconnection and closure of contacts during power outages, etc

☆ Automatically adapt to reverse phase sequence

☆ Direct indication of power supply, switching, alarm and other status LEDs

☆ The control terminal provides 2 common signal connection points, facilitating cascading wiring of multiple switches

☆ Rail mounted (limited to 30kvar and below capacity models)

Note 1: A dedicated controller for a single network synchronization switch can connect 32 network type synchronization switches, and the split compensation synchronization switch is only counted as one switch.

Note 2: The dedicated controller for network synchronization switches has two operating modes

Mode 1: Co compensation mode (requires connecting one sampling transformer); Mode 2: Mixed compensation mode (requires connecting 3 sampling transformers)

Ordering Notice

When placing an order, the user must provide parameters such as the rated voltage, rated capacity, co compensation type, and sub compensation type of the product
