The system consists of rectifier / charger, inverter, static bypass, maintenance bypass, rectifier isolation transformer, inverter isolation transformer, bypass line isolation transformer, automatic line stabilizer, DC distribution, AC distribution, controls and monitoring. The AC output of the inverter is connected to the critical load, the storage battery is connected between the inverter input and rectifier / charger output through a battery isolation MCB. The normal AC input power is connected to the rectifier; the bypass circuit also takes power from the same power source to provide power for the critical load during bypass operation when the system is in maintenance mode.
Technical Features
 |  |  | ||
| Adopting High-speed DSP Control | High Reliability | Advanced BMS | ||
Adopting voltage and current stepping technology under CPU control, the rectifier of UPS has a soft start function. The input step is less than 15 seconds (adjustable), and the maximum impact current on the power grid does not exceed the rated current. | Built-in input transformer, output transformer, and bypass transformer realize complete Galvanic isolation. Instead of discrete IGBT and SCR components, we uses Modular IGBT and SCR in Rectifier and Inverter, bringing in extremely high reliability. | Intelligent battery management, comprehensive charge and discharge management of batteries, including charging voltage and current limiting, discharge cut-off voltage, extending battery lifetime 30%-50% | ||
 |  |  | ||
| Flexible customization | Integrated design | Strong Impact Ability | ||
Industrial UPS can be customized according to the customer's environment, including input and output voltage, phase, frequency, battery voltage, charging current and IP level of the cabinet, etc; | the entire machine adopts a less fuse design, using circuit breakers, contactors, and electronic static switches. The circuit protection technology is advanced, greatly improving the reliability of the entire machine. | Adopting pulse-by-pulse technology to ensure that the maximum short-circuit current does not exceed the allowable range of single pulse short time IGBT, a pulse-by-pulse current limiting scheme is adopted. | ||
 |  |  | ||
| Suitable for harsh environments | Parallel operation | High compatibility | ||
It can be applied in harsh environmental conditions such as dust, pests, high-temperature conditions, and earthquake areas to protect your important production processes and systems. | Advanced distributed active parallel technology can realize parallel operation of 6PCS UPS units without the need for centralized bypass cabinet. | Compatible with Lead Acid ( vented/sealed) , NiCd (vented/gas recombination) batteries and lithium batteries. |
