OPQ5A Automatic transfer switch hot sales 3P/4P automatic generator changeover switch generator

Model description

Function of intelligent controller

TQ5A automatic transfer switch is a new device of high quality and intellectualization,

has many functions like automatic/manual operation, double break, power generation,

fire control, etc.. The controller inputs by the keyboard, displayed by LED, the intelligent

controller can detect the single phase of normal power (N) and reserve power (R)

synchronously: When detecting the situation of over-voltage, under-voltage, phase

failure or voltage loss, it will judge higher than 115% of the rated operating voltage as

the over voltage, and lower than 80% of the rated operating voltage as the under voltage,

the microc omputer makes corresponding processing to the test result, then it will send

out command, the processing result can be displayed by LED.

Application

OPQ5A automatic transfer switch (hereinafter referred to as switch) is only used for

transfer between two circuits of power supplies, not for the main power supply. This

product is applicable for dual-power system of AC 50H z, rated operating voltage 38 0V

and rated operating current 63A below, to serve the transfer between normal power

and reserve power by automatic or manual operation. It is mainly used in such fields

that need transfer between two circuits of power supplies like hospital, store, bank,

chemical engineering, metallurgy, high-rise building, military, etc..

Structure

JTQ5A automatic transfer switch, with reasonable construction, powerful functions,

stable performance, light weight, compact volume, convenient operation, is mainly

made up of power changeover actuating circuit breaker, there are three state positions

for selection, that is state I (N ON, R OFF), state III (N OFF, R ON) and state (N OFF, R

OFF). The switch has advantages of compact volume, stable performance, powerful

functions and so on, and wins favorable comments from users.

Power grid-power grid (R)

After starting up the machine, you have to regulate it to automatic and normal

power state first, when the power supply comes across abnormal situation, the normal

power indication lamp of controller LED will go out, and it will transfer to reserve

power after time delay and continue to supply power, when the normal power

resumes, it will transfer to normal power from reserve power again, with memory

function.
