Product Features FMQ4G series ATSE is composed of two parts: switch body and
changeover control. The switch is driven by solenoid coil and has
fast changeover speed. Type NA is a special integrated ATSE, with the intelligent
controller installed inside the switch body in a compact structure,
so that the user only needs to connect the main circuit and then it
can be put into use, which is convenient for the user to connect. N, C, M type is split external control, the controller and the
switch body are connected with a special cable to make the
installation and wiring more convenient. The N, C, M type is split
type external control, the controller and the switch body are
connected by a special cable to make the installation and wiring
more convenient. The integral type and split type also have the
function of detecting fault such as overvoltage, undervoltage and
shortage of two-way three-phase power supply, and the function of
starting and stopping signal output of generator set can be added
as an option (about 3 seconds delay when the main power supply
fails, and about 3 seconds delay when the main power supply returns
to normal).
