ATS— Automatic Transfer Switching
Necessity ： In order to ensure the continuity and reliability of power supply for important loads 。
Hospital Commercial Industry Factory Fire Protection
What is ATS
Function: when the normal power supply fails, it will automatically transfer to the
standby power supply
What is ATS
VS
PC Class CB Class
The actuator is the circuit breaker The actuator is a disconnector
Faster conversion time, ≤ 250ms Longer conversion time, 1000～2500ms Without over current protection With over current protection
CB class is mainly concerned with load safety
PC class mainly concerned with continuous power supply
Differences between PC and CB class
PC Class
（Disconnector type） CB Class
（Circuit breaker tpye）
Overload and shortcircuit
protection NO YES
Actuator Disconnector Circuit breaker
Driving mechanism Electromagnetic coil Motor
Action time 100～250ms 1000～2500ms
Reliability High Low
Volume 1 / 2 of the same level of CB Big

添加标题What is ATS
ATS has 3 conversion methods
Self-throwing
& Not Self-reset Self-throwing
& Self-reset
Grid to Grid
Self-throwing means when the normal power fails, the power supply will automatically switch to the standby power supply Self reset means that when the normal power returns to normal, the power supply will automatically switch from the
standby to the normal power

Highlights of NXZ series
Generator Control
Only for grid-generator mode
When the normal power fails, ATS will send a closing signal to the generator
Generator Grid
When the ATS receives the fire signal, the ATS will break the normal power and the backup power at the same time, Then output a feedback signal
