Brief Introduction For Kpec Series Ats Cabinet; Brief Introduction For Automatic Transfer Switching (Ats) - Kipor KPEC Series User Manual

2. Brief introduction for KPEC series ATS cabinet

KIPOR KPEC series ATS cabinet applies intelligent controller KPD100 and automatic transfer
switching (ATS), and shells with cabinet of IP32 and IP54 protection grade. It can realize the
manual/auto switching on multi power supply system at various switching modes according to the
various customer requirements.
2.1 Brief introduction for KPEC series ATS cabinet
KPEC series ATS cabinet is the KPD100 intelligent controller and ATS control system researched
and developed by KIPOR, which integrates the digital, intellectual and networking technology,
realizes manual/auto switching control between standby and main power, and obtains the data
measuring, alarm protection and 3 remote functions. It features compact design, convenient wiring,
simple handling and reliable operation.

2.2 Brief introduction for automatic transfer switching (ATS)

Automatic transfer switching (ATS) features:
(1) Conform to the international standard.
There is standard from International Electrotechnical Commission especially for ATS, i.e.
IEC60947-6-1. Automatic transfer switching (ATS) accords with this standard and has passed the
certificate of KEMA testing institute.
(2) Integrated design.
(3) Dual interlock of mechanical and electrical. ATS has reliable mechanical interlock and will never
power on two supply lines simultaneously. This is controlled by the ATS controller through the
control over electromagnetic drive coil.
(4) Electromagnetic drive switch, with high speed.
Depend upon the unique electromagnetic coil driving, with the switching time within 0.2s (open-loop
switching mode). As electrical switching on both the two power lines may generate electric arc
conduction (about 0.12s), the actual time of load power off will not exceed 0.5s.
(5) Internal mechanical state remaining mechanism
ATS is driven by electromagnetic power. The coil only works during switching, therefore greatly
increase the lifespan of the actuating element.
(6) High withstanding capability to short circuit
ATS is to switch between two power supplies, bearing no protection function. When short circuit or
overload occurs, ATS only can withstand but not trip. So it is not until the breaker trips will not the
ATS stop withstanding the high current. This withstanding capability may equal or exceed the short
circuit breaking capability of ATS front-end circuit breaker.
