SDL Three-entry Single-out Dedicated Power UPS
SDL three-entry single-out dedicated power UPS description: SDL three-entry single-out dedicated power UPS is designed for dedicated power
plant, substation design, with online, zero-delay conversion
function, are mainly used in the load voltage for better places,
such as power telecontrol, RTU, power line carrier, monitoring and
so on. Dedicated UPS power circuit structures such as icons, electricity
is normal, single-phase 220V AC (or three-phase 380V) After
isolation, the filtered rectified power to the inverter, if the AC
input power failure, will be owned by the electric power system the
DC-screen through the anti-anti-diodes to the inverter, and then
through the output isolation to the important post-load power; if
the DC panel power outages, are being examined by AC input power
supply; if the inverter overload or a failure by the static switch
to the bypass supply.
Features: 【Improve the quality of supply】 Through the input and output isolation, as well as dual-mode
dual-conversion to output a standard voltage regulator sine wave
frequency stabilization. From the input power changes. 【Electricity brown-out protection】 If the input supply power, UPS power system owned by the DC panel
power supply (DC110/220V), the load power without interruption. 【To improve noise rejection】 As the use of isolation transformers and AC - Direct - AC
conversion method, input power of the clutter is effectively
filtered, so that the load can get clean power. 【Diode internal installation of backstop】 UPS DC input side and DC bus connected between the diode through
the backstop to prevent DC bus voltage is higher than the DC input
side of voltage to the DC-screen anti-irrigation, play a role in
protection of DC panel. 【AC bus and DC bus isolation】 Completely shielded communication bus and the interaction between
the DC bus. 【Delay soft-start function】 Delay with a complete soft-start function, can greatly reduce the
system startup process equipment and grid impact. 【Alarm and protection functions】 With a variety of alarm mode is available through sound, light,
LCD, input and output contact and communication transmission of the
current alarm occurred in timely, accurate and detailed tips,
improving system reliability, while helping maintenance personnel
to quickly and accurately locate and troubleshooting. Passive fault
contact. 【Protection】 With input received anti-protection, input under-voltage
protection, input over-voltage protection, output overload
protection, output short circuit protection, over-temperature
protection 【Communication function】 With RS232/485 communication interface can communicate with the
host computer.
