on DC UPS Systems
what is a DC UPS?
A DC UPS (Direct Current Uninterruptible Power Supply) ensures that connected devices are reliably supplied with power even in the event of a power cut or voltage fluctuations. Unlike traditional AC UPS systems, a DC UPS operates directly with direct current, e.g. 12 V, 24 V or 48 V, and supplies control systems, sensors, communication systems or safety-critical applications without interruption.
which applications require a DC UPS?
A DC UPS is used wherever electronic systems need to continue operating reliably even in the event of a power cut or voltage fluctuations.
These include:
• Industrial Automation
• Transport Infrastructure
• Medical Technology
• Telecommunications
• Building and Security Technology
• Renewable Energy
• Measurement and Monitoring Systems
You can find detailed information on the areas of application here.
how does a UPS work?
A UPS consists of a mains power supply, a DC UPS with charging electronics, and an energy storage system – usually in the form of batteries or rechargeable batteries. During normal operation, the mains power supply feeds the loads whilst simultaneously charging the battery. If the mains supply fails, the DC UPS switches over seamlessly and the energy storage system takes over the power supply.
what is a DC UPS module?
A DC UPS supplements an existing DC infrastructure by providing a pure bridging function. It fits neatly into existing system environments, such as electrical cabinets, and is particularly suitable for users who wish to expand or scale their system in a targeted manner. In addition to a DC UPS module, an energy storage unit is required, which may, amongst other things, be integrated into the module itself.
what is an all-in-one UPS?
All-in-one systems combine a power supply unit, battery and UPS module in a single unit. They are the first choice for new installations or wherever a turnkey, quick-to-install solution is required without any existing infrastructure.
what happens in the event of voltage fluctuations or a power cut without a DC UPS?
There are many areas in which a reliable power supply is essential. This applies, amongst other things, to measurement and control technology, where control systems, sensors or communication systems would fail without the use of DC UPS systems. A power cut or voltage fluctuations can, for example, lead to production stoppages, data loss, equipment malfunctions or safety-critical situations – and result in financial loss or even a risk to life and limb.
what are the typical voltages for DC UPS systems?
Typical output voltages are 12 V, 24 V and 48 V DC. In industrial applications, 24 V DC is particularly widespread, as many control systems, sensors and automation components operate at this voltage.
how long can a DC UPS power a system?
The backup time depends on the capacity of the energy storage system and the power consumption of the connected loads. Depending on the application, it can range from a few minutes to several hours.
what types of energy storage are used in DC UPS systems?
Depending on the application, different energy storage systems are used, such as lead-acid batteries, lithium iron phosphate batteries or supercapacitors. The choice depends on factors such as service life, temperature range, maintenance requirements and space requirements. We provide detailed information on the differences and advantages of the various energy storage technologies in our Webinars
which devices can be protected by a DC UPS?
A DC UPS can be used to protect the following components, amongst others:
- Programmable Logic-Controller (PLC-Systems)
- Sensors and Actuators
- Industrial PCs
- Communications and Networking Technology
- Security Systems
- Measurement and Monitoring Technology
how is the appropriate DC UPS sized for a particular application?
When selecting a DC UPS, three factors in particular must be taken into account: output voltage, the power requirements of the connected devices and the required runtime. On this basis, we determine the appropriate DC UPS module and battery capacity.
how is a DC UPS monitored and maintained?
Many of our systems are equipped with diagnostic and monitoring functions. This enables the condition of the battery to be identified at an early stage, allowing for its replacement to be planned before its ability to provide a temporary power supply is compromised.
can DC UPS systems be retrofitted into existing installations?
Yes. Our DC UPS systems can generally be integrated into existing DC power supplies without any problems. They are installed between the power supply unit and the load and, using an external or internal energy storage device, automatically take over the power supply in the event of a mains failure.
what is an UZB?
An UZB is a plug-and-play battery module that is connected externally to the DC UPS module.
