ETT (10-120KVA) series three-phase power frequency UPS is designed for high-performance sine wave high-power uninterruptible power supply designed for data centers, network computer rooms, and intelligent precision equipment (such as measuring devices, industrial automation equipment, etc.). It adopts excellent digital control technology, SPWM inverter with excellent performance, intelligent multi-mode battery management technology and other foreign technologies, and friendly LCD interface design to make man-machine communication zero distance; The functions of understanding the working history, parameter monitoring, automatic power on/off, unattended and remote network monitoring (through SNMP card) between UPS and PC through RS232 communication port can be adapted to the use of excellent network system, with good cost performance and user base. Its high reliability provides important power protection for high-power equipment in industries such as finance, communications, insurance, t

EM330 series module UPS, power module 20/30KVA/3U, a single cabinet supports 10 power modules in parallel up to 300KVA, and 4 units can be connected in parallel between a single cabinet and a single cabinet to achieve a power of 1200KVA. Each power module has an independent DSP control unit, and in the event of a power module failure, it is automatically isolated from the system and the system can continue to operate.

EDD single-in, single-output power UPS is specially designed for power plants and substations, with online zero-delay conversion function, mainly used in places with high load voltage requirements, such as power telecontrol, RTU, power carrier, monitoring, etc.

ESD three-in, single-output power UPS is specially designed for power plants and substations, with online zero-delay conversion function, and is mainly used in places with high load voltage requirements, such as power telecontrol, RTU, power carrier, monitoring, etc.

The total system is composed of four subsystems: AC power subsystem, DC power subsystem, inverter power subsystem, and communication power subsystem, each subsystem is composed of an independent configuration menu and a real-time data query menu. The size of each subsystem is affected by the total system configuration, so the size of the subsystem must be configured in the total system configuration menu to make detailed parameter configuration for the subsystem. For example, if the number of AC screens is set to 0 in the total system maintenance configuration, the AC subsystem will not be able to enter the AC subsystem for configuration, and the AC subsystem will not have the monitoring function. Because the configuration of the master system is related to the data structure of the whole system, if the maintenance level parameters of the master system are modified, the restart must take effect.

Equipped with a 7-inch large-screen color LCD touch screen, it can query the voltage, current, frequency, active power, reactive power, electricity, harmonics and other power quality status of each main and branch circuit at any time, and can record the load curve changes in real time, as well as the redundancy ability of the system in the event of partial failure

UPS incoming and outgoing power distribution cabinets all adopt Hailian's new GDH NR system, flexible cabinet structure, easy to realize cabinet combination, parallel installation between cabinets, etc.

The inlet and outlet lines of the UPS outlet cabinet are all Schneider NSX series molded case circuit breakers, and the thermal-magnetic trippers are selected, and the upper and lower levels of the circuit breakers are selectively coordinated.

It further integrates the company's new research and development achievements in recent years, especially the multi-loop electric energy metering and monitoring technology, circuit breaker hot swap and phase modulation technology, and large-screen LCD touch screen technology, so that the function of the precision power distribution cabinet is increasingly perfect

Usually, the lighting of the data center is bright, and there are no lighting windows and no suspended ceilings, but the accuracy of the computer room is very high. Therefore, in addition to considering the energy metering control to achieve the purpose of efficient use, the continuity of lighting is also required.
