DDL Single-entry Single-out Dedicated Power UPS

DDL single-entry single-out dedicated power UPS description:
DDL single-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.
