Installation Guide

Preface
The Automatic Transfer Switch (hereafter referred to as ATS) uses world-famous ATS or AC Contactors as
the main switches, and are manufactured from advanced and closely-controlled production processes. It is
combined with all our automatic generators to form a complete and thorough Automatic Transfer System.
The DKG-173 Transfer Controller is installed inside the ATS, which applies to three phase or single phase
systems with phase voltage of 220v AC. Pluggable connectors are connected with external connections, which
make the maintenance, inspection, or replacement easy and convenient.
We have 125A single phase ATS, 125A three phase ATS, and 200A single phase ATS for your different needs in
various conditions.
Functions
ATS has control functions (such as generator start-up delay, mains restore delay and voltage
detection, etc.). When the ATS is connected to automatic generators, the generator's control
box will send the transfer signal in order to transfer loads automatically. It can operate with our automatic
control systems or other brands that have remote-start self-control functions which are simple and economic.
