Power supply units
Power supplies and power supplies from Feas - Made in Germany
A power supply or power supply unit is used to supply power to devices or assemblies that require different voltages and currents than those provided by the power grid. Power supplies are divided into switching power supplies and transformer power supplies, the latter of which can be distinguished into regulated and unregulated ones.
We offer you a variety of power supplies that are tailored to your respective application. Whether a power supply unit for control cabinets, sub-distributions, uninterruptible power supplies, power supplies with DIN rail or power supplies with extremely high degree of protection, we have the right power supply for all applications - contact us!
The high-quality power supplies from Feas are manufactured according to the highest industry standard and in compliance with the relevant regulations. The power supplies, which are suitable for the tropics due to their casting resin full encapsulation and have a high degree of protection against vibration, condensation, etc., are suitable for all industrial sectors.
Standard Power Supplies
The output voltage of the power supplies is in a wide range between 5Vdc and 230Vdc
Depending on the type and technology, the input voltage ranges from 85 to 550Vac, and 1-phase and 3-pahsen power supplies are also available.
The power supplies are equipped with the available technologies such as screened-smoothed, linear control or switching power supply.
LED power supplies - optimized for applications with light-emitting diodes
With the LED switching power supply, the mains voltage is converted into a regulated output voltage. After filtering and rectiving, the input AC voltage is converted into a high-frequency wave-like pulsating voltage with a pulse width modulated semiconductor switch and transformed into the required voltage by means of a transformer to the secondary side. It is then rectified and filtered. The higher power supplies are all equipped with Power Factor Correction (PFC).
The regulated LED power supplies are ideal for powering LED displays and control panels.
The LED switching power supplies supply LED displays with a stabilized output voltage. Therefore, the LED power supplies are particularly suitable for the power supply of LED billboards or other applications with LEDs. The LED power supplies are also used, for example, in electronic show boards or stadium banner boards.
ASi Power Supplies - Power Supplies with Certified ASi Interface
ASi power supplies are special switching power supplies (SNT) whose interfaces are certified according to ASi, and thus facilitate cooperation with components from other manufacturers.
Tests and certification ensure that the devices from different manufacturers work together. The powerful and robust ASi switching power supplies are ideal for supplying sensitive consumers in harsh industrial environments.
The AS-Interface (ASi=Actuator-Sensor-Interface) is a standard for fieldbus communication that has been developed for connecting actuators and sensors. The aim is to replace the previous parallel cabling. The AS-Interface is mainly used at the sensor/actuator level. The AS-Interface has been an international standard according to EN 50295 and IEC 62026-2 since 1999. The certification of ASi products is carried out by the AS-International Association.
Buffered Power Supplies - Power Failure Bridging Power Supplies - DC UPS with Battery
The buffered power supply is switched between the mains voltage and the system in order to supply them with DC voltage. The device stores the energy in batteries as long as the power supply provides the voltage. In the event of a failure of the mains voltage, the buffered power supply takes over the load current for a certain period of time. As a result, e.B operations can be terminated in a defined way or process data can be stored to enable controlled restarts.
With buffered power supplies, you can supply your systems with power and protect them from power outages at the same time!
The buffered power supplies are uninterruptible power supplies (DC UPS) with power supply and batteries. They reliably supply your systems or assemblies with the required energy. The built-in batteries ensure a bridging even in the event of mains interruptions to protect your consumers – depending on the device in the range of seconds or up to 2 hours.With the buffered power supplies, you ensure a steady power supply even in the event of disturbances due to mains voltage faults, peak loads and switching processes. The reliability of your overall system is significantly increased.
Installed and fully encapsulated in an aluminum housing, the robust buffered power supplies are characterized by vibration resistance, industrial and tropical suitability.
High-protection power supplies (IP65/IP68/IP68K)
Power supplies (IP65/IP68) - vibration-resistant, tropical compatible, IP65 to IP68K
The casting resin full encapsulation of the power supply electronics, embedded in a sturdy aluminum housing, ensures high vibration resistance, dust protection and moisture protection of classes IP65 to IP68K for the power supplies (IP65/IP68).
The power supplies as a cable version also meet at least the requirements of protection class IP65 due to the casting resin full encapsulation and reliably sealed cable inputs and outputs and LEDs, power supplies without potentiometers even up to IP68. But even with devices with potentiometers, you can usually achieve protection class IP68K by subsequent sealing.
IP protection classes define the protection of electrical equipment against contact, foreign bodies and water. Enclosures and covers must be designed in such a way that they comply with the required IP protection classes.
The IP protection classes have the following significance:
- IP65: tight against dust, protected against contact and against water jets
- IP68: tight against dust, protected against contact and even against permanent immersion
- IP68K: additionally protected against hot water jets (100bar, 80°C)
Power supplies for 19 inch slot
Do you need power supplies for installation in 19" slide-in frames?
This housing of the powerful and robust switching power supplies is adapted to the installation in 19 inch bays. The functional and stable aluminium housings are manufactured in the 3U 8TE version.
These power supplies for 19" slide-in frames are available as versions with or without partial front panel 3H with handle.
On the back there are different connection variants:
- via power strip H15
- via cable
- Primary connection via terminals and secondary connection via cable
- wall mounting is also possible.
General information about the switching power supply:
The switching power supply converts the mains voltage into a regulated output voltage. After filtering and rectiving, the input AC voltage is converted into a high-frequency wave-like pulsating voltage with a pulse width modulated semiconductor switch and transformed to the required voltage on the secondary side by means of a transformer. It is then rectified and filtered. The higher power supplies are all equipped with Power Factor Correction (PFC).
Power supplies for sub-distributions
Do you need power supplies for installation in electrical distributors?
These powerful and robust power supplies are particularly suitable for use in control cabinet construction. The dimensions of the functional and stable aluminium housings are perfectly matched to the installation of the power supply in electrical distribution boxes. The installation in the fuse box is very easy via a DIN rail.
