1 OVERVIEW

HMAT880 Medium Voltage Bypass ATS Controller is a module that integrates programmable
function, automatic measurement, PT break detection, load stepwise switch, LCD display and digital
communication. It combines digital, intelligent and network technology, realizes automation of
measurement and control process, thus reducing manual operation error, which is an ideal product
for medium voltage bypass transfer.
HMAT880 Medium Voltage Bypass ATS Controller is composed of microprocessor as the core,
which can precisely detect 2-way 3-phase incoming voltage, make accurate judgment for voltage
abnormal situations (over/under voltage, over/under frequency, loss of phase, reverse phase
sequence) and output passive control coil. It fully considers various applications in bypass switch
and can be directly used for single bypass, dual bypass switch, also for manual/remote control switch.
With compact structure, advanced circuits, simple wiring and high reliability, it can be widely used in
electric device, server supply and debugging system of electric power, telecom, petrochemical
industry, mining, railways, municipal administration, data center, intelligent building and other
industries.
