Architecture and operating principle of industrial UPS series DKS
Industrial uninterruptible power supplies, classified as heavy-duty, are built using the Online Double Conversion scheme. This means that the input AC voltage is first rectified to DC and then inverted back to AC with a perfect sine wave. This architecture completely isolates the connected equipment from interference, dips and power surges in the external network.
The key element of any UPS system is the rechargeable battery (AB). It is the quality and type of batteries used that determine the battery life and service life of the entire system. Solutions from Nanjing Qiantan Energy Storage Technologies LLC use specialized lead-acid batteries designed to meet high requirements for cyclic life and stability of characteristics. In particular, for long-term backup tasks, gel batteries of the OPzV and CG series are used, which demonstrate excellent results with deep discharges and operation at elevated temperatures.
The engineering feature of DCS systems is their ability to withstand inrush currents characteristic of active and reactive equipment. When choosing a UPS, it is necessary to take into account not only the active power (kW), but also the apparent power (kVA), as well as the power factor of the load. Our specialists conduct a detailed audit of the customer’s energy consumption to eliminate the risk of inverter overload in transient modes.
Factors in determining the price of an uninterruptible power supply DKS
The cost of an uninterruptible power supply system is not a fixed value and depends on many technical and logistical parameters. Understanding these factors allows purchasers to optimize budgets without compromising system reliability. When you're looking for an opportunitybuy uninterruptible power supply DKS, the price from the manufacturer is based on the following components:
- Power of the inverter module.The higher the rated power (from 10 kVA to several MVA), the more complex the circuit design and the more expensive the power switches (IGBT transistors). For small server rooms, 10-20 kVA models may be sufficient, while industrial lines require cabinets rated at 100 kVA or higher.
- Capacity and type of battery bank.This is the most variable part of the cost. The use of tubular monoblocks of the CL 2V series ensures a long service life (up to 15-20 years in buffer mode), but has a higher initial cost compared to standard AGM batteries. The OPzV gel technologies offered by our company occupy an intermediate position, providing an excellent balance of price and durability.
- Level of intelligent control.The presence of SNMP cards, controllers for monitoring the status of each battery (BMS - Battery Management System) and integration with dispatch systems increase the cost, but are critical to prevent sudden failures.
- Design.Execution in the form of rack-mount modules (Rack-mount) or floor-standing cabinets (Tower) affects the cost of the case and cooling system. Industrial versions often have enhanced protection against dust and moisture (IP rating).
- Logistics and customs clearance.Direct deliveries from the manufacturer, such as those carried out by Nanjing Qiantan Energy Storage Technologies LLC, allow you to minimize logistics costs by optimizing routes through China, Russia and other countries of presence.
It's important to note that saving on batteries often results in a multiple increase in total cost of ownership (TCO) due to the need for frequent cell replacement. Our company, being a full-cycle operator, including recycling of used batteries, offers environmentally friendly and economically sound solutions.
Technical parameters and selection requirements
To select the equipment correctly, it is necessary to compare the characteristics of the UPS with actual operating conditions. Below is a table of typical parameters that should be taken into account when creating technical specifications.
| Parameter | Description and influence on choice | Recommendations of Nanjing Qiantan LLC |
|---|---|---|
| Input voltage | The range of permissible network fluctuations without switching to batteries. | A wide range of input voltages reduces battery wear. Our UPSs support operation under significant frequency and voltage variations. |
| Power factor (PF) | The ratio of active power to apparent power. PF=1.0 means that all power is used usefully. | Modern UPSs must have an output PF of at least 0.9, and preferably 1.0, in order to effectively power modern server power supplies. |
| Inverter efficiency | Energy conversion efficiency. Affects heat dissipation and energy costs. | Choose models with >95% efficiency online. This reduces the load on the server room's air conditioning systems. |
| Battery type | AGM, Gel (OPzV), Li-Ion. Determines service life and temperature conditions. | For long-term backups and high temperatures, we recommend OPzV or CG gel batteries from our range. |
| Switching time | Delay in switching to batteries. For online UPS it is zero. | Purely online technology (Double Conversion) guarantees zero switching times for sensitive electronics. |
Comparative analysis of battery technologies for UPS DKS
The choice of battery base is a decisive factor in system reliability. Many buyers focus only on the brand of the UPS itself, ignoring the fact that up to 70% of failures of uninterruptible power supply systems occur precisely because of problems with the batteries. Nanjing Qiantan Energy Storage Technologies LLC offers a wide range of solutions that allow you to choose the best option for your specific budget and tasks.
| Characteristics | Standard AGM batteries | Gel batteries (OPzV/CG) | Tubular monoblocks (CL 2V) |
|---|---|---|---|
| Service life (buffer mode) | 5-7 years | 10-12 years | 15-20 years |
| Cyclic resource | Low (up to 300 cycles at 80% discharge) | Medium (up to 600 cycles) | High (up to 1500 cycles) |
| Temperature resistance | Sensitive to exceeding +25°C | Better thermal stability | High resistance to changes |
| Cost of ownership | Low initial, high final | Balanced | High initial, low final |
| Application in UPS DKS | Short-term reservation (minutes) | Medium term (hours), difficult conditions | Critical infrastructure, long standby |
The table shows that for applications where long battery life is required or where room temperature is not always perfectly controlled, OPzV and CG series gel batteries are the preferred choice. They do not emit gases during normal operation, which allows them to be installed in close proximity to electronic equipment without complex ventilation systems.
An engineering view: the risks of incorrect selection
From the point of view of engineering practice, one of the most common mistakes is calculating the capacity of a battery bank only according to the passport data of the UPS manufacturer, without taking into account battery aging and temperature coefficients. The capacity of a lead-acid battery drops by approximately 50% when the temperature drops from +25°C to 0°C. If your property is located in a region with a cold climate (for example, Siberia or Northern Kazakhstan), the standard calculation will be incorrect.
Nanjing Qiantan Energy Storage Technology LLC takes these nuances into account at the design stage. We leverage data from our high-temperature battery and front-terminal solutions (HFS and CT Series) to compactly fit server cabinets into tight spaces. Our experience in implementing projects in Russia, Iran and other countries with diverse climates confirms that adapting a solution to local operating conditions is more important than simply following standard catalog specifications.
Application of uninterruptible power supplies DCS in industry
DKS class systems are used not only in the IT sector. Their reliability is in demand in industries where equipment shutdown leads to enormous financial losses or safety hazards.
Oil and gas sector and energy
At pumping stations and distribution substations, UPSs provide power to automation and telemetry systems (SCADA). Protection against impulse noise that occurs when switching high-voltage equipment is critical here. The use of stationary batteries of the CP series from our production guarantees voltage stability in control circuits even during long-term accidents in the external network. The local engineering support that we provide to partners in Russia and Turkey allows us to quickly resolve issues related to the installation and configuration of such systems.
Telecommunication centers
Cellular base stations and data transmission nodes require round-the-clock operation. They are often located in unheated rooms or containers. Under such conditions, traditional AGM batteries quickly degrade. Our solution is the use of OPzV gel batteries, which remain operational over a wide temperature range. In addition, the presence of a specialized workshop for environmentally friendly recycling of used batteries in the structure of our company allows our partners to comply with strict environmental standards when disposing of old batteries.
Production lines and automation
Modern factories are full of programmable logic controllers (PLCs) and frequency converters. A short-term voltage dip can lead to a program reset and the conveyor stopping. The DKS UPS, equipped with high-power solutions with front terminals (HFS series), ensures fast connection and maintenance in cramped electrical panels. The experience of our specialists, who have worked in leading Chinese battery enterprises and international corporations, allows us to integrate power systems directly into the customer’s technological process.
