YDQ6 series dual power automatic conversion switch is mainly used for AC 50Hz ,, rated voltage 380V. DC rated voltage 220V, rated current or motor power distribution network 16A to 1600A of a main one or mutual load standby power switching systems and generator sets and mains switch. At the same time it can be used for infrequent making and breaking circuit and circuit isolation purposes.
Our products are widely used in fire fighting, hospitals, banks, high-rise buildings and other places not allowed off important supply of transmission and distribution systems and automation systems.

Six control features
● Dual power switch with a three-pole four poles (three poles + neutral pole can be off) product.
● Dual power development is divided into 20A, 40A, 63A, 80A, 100A, 125A, 160A, 200A, 225A, 250A, 315A, 350A, 400A, 450A, 500A, 630A, 800A, 1000A, 1250A, 1600A and other 20 current levels .
● basic types: primary - backup power, automatic recovery.
Type I: 100A or less, mains - mains, since the vote since the complex, two-way power three-phase phase detection; 125A above, mains - mains, standby or mutual support Alternatively, since the vote, two-way power three phase detection;
Type II: mains - mains, standby or mutual support optional (ie, automatic recovery or from a vote of no self-recovery), two-phase power supply phase, over undervoltage detection;
Type III: Mains - oil machine, automatic recovery, two-way power three-phase phase, over-under voltage, oil-frequency detection.

Seven basic switching control features
● applies to two standby system power, automatic recovery;
● external functional extensions.

eight, I type switch control features
● 100A of the following:
A, suitable for two-way dust Standby mains;
B, when the main power supply circuit malfunction (power failure or phase) switch after delay (can be set 1 ~ 16s) is automatically put into the standby power supply circuit.
C, when the mains supply returns to normal, the switch by the delay (can be set 1 ~ 250s) automatically switches back to the main power supply circuit.
● 125A above:
A, applicable to primary and secondary system two mains or mutual backup systems.
B, switch selected as the automatic recovery function (ie primary and secondary type). When the mains supply fails (power failure, phase), switching by the delay (can be set 1 ~ 16s) is automatically put into the standby power supply circuit; when the main circuit returns to normal, the switch by the delay (can be set 1 ~ 120s) Automatic Cut back to the main power supply circuit.
C, switch selected from a vote of no self-recovery capabilities (ie mutual standby type) ,. When I channel power circuit failure (power failure, phase); a switch by the delay (can be set 1 ~ 16s) automatically into II-way power circuit; when the power supply circuit II returns to normal, the switch does not cut back to the I-way. II road only when the power circuit failure; a switch only by the delay (can be set 1 ~ 120s) automatically cut the loop I-way power circuit.
● Priority power supply circuit terminal selection by the patch.

Nine, type II switch control features
● suitable for two-way mains standby system or mutual backup systems.
● switch selected as automatic recovery function, when the main power supply circuit malfunction (phase, over voltage) switch after delay (can be set 1 ~ 16s) from automatically into the standby power supply circuit; when the main circuit return to normal: switch by the delay (can be set 1 ~ 120s) automatically switches back to the main power supply circuit.
● switch to select the automatic switching when no self-recovery function, when the I-way power supply network failure (phase, over voltage); a switch by the delay (can be set 1 ~ 16s) automatically into the II-way power circuit; when When the I-way power circuit returns to normal, the switch does not cut back to the I-way, the road only when I power circuit fails, the switch only after delay (can be set to 1 ~ 120s) automatically switch back to I-way power circuit.
● Select priority power supply circuit (125A and above) through the terminal.

ten, III switching control features
● applies mainly to the mains power supply, standby generators powered systems.
● When the mains fails, the switch controller first sends oil machine start signal, after switching delay 3s, switch first to invest in "O" position, and then when Ting (warm-up time adjustable 1 ~ 250s) automatically into oil machine power supply circuit.
● When utility power is restored to normal. Switch by the delay (can be set 1 ~ 250s) automatically switch back to the mains supply, then delay (can be set 1 ~ 250s), the controller sends out a signal to close oil machine.
● Mains, a three-phase oil-phase, three-phase over-under voltage detection, oil-frequency detection.

XI, these four switches are characteristic
