Modular UPS Solutions

Modular UPS adopts standard structure design, each system consists of power module, monitoring module and static switch. The power modules can be connected in parallel to share the load equally. In case of failure, the system will automatically exit the system, and other power modules will bear the load, which can expand both horizontally and vertically. The unique redundant parallel technology makes the equipment no single point of failure to ensure the highest availability of the power supply. All modules can be hot-swapped and replaced online. Maintenance is the safest power protection solution.

This solution is composed of a modular UPS host, an intelligent power distribution system, and a battery. Modular UPS host:

The modular UPS power module adopts a double-conversion on-line structure, including rectifier, inverter, charger, control circuit, and circuit breaker for input and output battery busbars. With input power factor compensation function. All modules are hot-swappable online, providing the highest level of availability and maintainability.

The modular UPS host control module adopts the industrial CAN BUS bus control structure, and the control and management of the system is completed by two redundant hot-swappable control modules. A control module failure will not affect the normal operation of the system. The control module can be hot-swapped and replaced online. The parallel connection of power modules is also centrally managed by the control module, and operates according to the unified parallel parameters. A power module failure can automatically exit the parallel system without causing harm to the entire parallel system.

The modular UPS system uses an independent static bypass module instead of multiple static bypass structures to avoid overload damage caused by uneven current flow of multiple bypasses when transferring to bypass. The module parallel output voltage accuracy is ±1%, and the parallel circulating current is less than 1%.

Standard SNMP card, using HTTP protocol, SNMP protocol, TELNET protocol and so on. The mains status, battery status, bypass status, inverter status, self-check status, power-on status and input voltage, output voltage, load percentage, input frequency, battery voltage, battery capacity, battery discharge time, UPS machine The operation status of the UPS power supply, such as the internal temperature and the surrounding environment temperature, is clear at a glance, which improves the management efficiency and management quality of the UPS power supply guarantee system. Select the open windowsNT/windows2000/windowsXP/windows2003 operating system platform.

A temperature and humidity sensor can be optionally equipped, and a multi-function network card can be inserted to monitor and alarm the temperature and humidity of the computer room environment through the network.

Intelligent power distribution system

The system is an integrated power distribution system for the input and output of UPS power supply. It is used together with the UPS host. It includes the input switch, output switch and maintenance bypass switch of the UPS, as well as the main input switch of the system. The main switch is equipped with auxiliary contacts; Contains a current sensing system and communicates with the UPS host.

The power distribution system consists of an input power distribution unit, a branched output power distribution module, a monitoring module, and an isolation transformer. Output power distribution unit Each power distribution module is equipped with 18 output branches, the current of each branch can be set from 6A-32A on demand, and the three-phase balance is adjusted according to the configuration and changes of the on-site load. The power distribution system can be Install up to 6 plug-in power distribution modules, and the number of power distribution modules is optional.

The power distribution system has the same size, appearance and color as the UPS host. The standard configuration is: LCD display, UPS maintenance bypass panel (including system main input switch, UPS input switch, output switch, maintenance bypass switch, with auxiliary contact switch). Detection circuit main board, three-phase input and output voltage and current sensor components, neutral current and ground current sensors, and external EPO signal interface.

Optional input K value isolation transformer and branch current monitor.

The power distribution system can be equipped with a network card, which can monitor the parameters, status, historical records and alarm information of the power distribution cabinet through the network. It can monitor the input and output three-phase voltage, current, frequency, neutral current, ground current, KVA number, KW number, power factor, branch current, etc. of each phase of the power distribution cabinet. And can set the current high and low voltage alarm threshold.

External battery and battery cabinet

The battery is a maintenance-free fully enclosed lead-acid battery. The battery capacity can be configured according to the brand. The battery is installed in a battery cabinet with the same brand, appearance and color as the UPS host.

Modular UPS Best Performance Features

Has a variety of working modes

The product has a variety of standard options, easy to operate, and can realize a variety of incoming and outgoing lines: 1/1, 1/3, 3/1 or 3/3, the input frequency can be 50Hz or the output frequency can be set to 60Hz, output The voltage can be set to 220V, 230V, 240V. If the input and output transformers are reconfigured, the power supply needs of all countries and regions around the world can be met.

Small size, high power density

High working efficiency and high power density are its biggest features. Can provide 5KVA (4000W), 10KVA (8000W), 15KVA (12KW) and 20KVA (16KW) power output.

Environmentally friendly

The total harmonic distortion (THDI) of the UPS is 3%, and the output total harmonic distortion under linear load is less than 2%, which minimizes the harmonic interference to the power grid and effectively reduces the power grid load and power loss. Excellent input parameters, showing pure resistance characteristics to the mains grid, is an ideal environmental protection and high-efficiency UPS.

And the size of each module is designed according to the standard 19-inch structure, so that the overall shape of the machine is consistent with the standard rack, which beautifies the appearance of the machine, and the modules can be used in common with the standard rack.

Redundancy, decentralized parallel logic control

The parallel control between the modules adopts the distributed logic control method, there is no distinction between the master and the slave, and the dialing or insertion of any module will not affect the normal operation of other modules, and constitute N+1, N+X as needed. The redundant system reduces the risk factor of the system itself and the load, and the load is fully protected by the UPS. It not only increases the reliability of the whole machine, but also simplifies the difficulty of user maintenance.
