Energizing Productivity Device series PxTFX IN = 20 A, IMAX = 40 A UZ ≤ 1.000 VDC Storage several kJ

The new generation of active energy management devices Your benefits Recovering braking energy Increase energy efficiency Increase productivity Controlled stops in case of power failure Bypassing power failures Mains-independent operation Compensate voltage dips No heat from braking energy Reduce load peaks Modular system Protect power quality Save money

Energizing Productivity Key features of the PXTFX devices Performance 20 amps continuous current 40 amps peak current for 60 seconds1 up to 18 kilowatts peak power Wide voltage range Min. Operating voltage level 180 VDC Max. Operating voltage level 848 VDC (UL) / 1000 VDC (IEC) Min. starting voltage level for the system (DC link or energy storage) approx. 45 VDC Safety functions Reverse polarity protection to DC link Integrated precharge circuit LSS charge protection switch: connection of charged energy storage modules possible Integrated load monitoring on both sides Internal fuses...

Energizing Productivity Realize advantages! Increased productivity Goal: Raise output quantity substantially Portion cutter for poultry meat Situation: A portion cutter for poultry meat performs with maximum cutting speed 17 cuts/s. A further acceleration leads to instability of the DC link and stresses the drive electronics. Solution: By integrating the active energy management device PXTFX with an energy module in the substructure the cutting rate can be increased to 25 cuts/s. Integrated into the existing system as a retrofit the system provides the DC bus with exactly the energy it...

Managing braking energy Goal: Higher dynamics and longer service life of drive electronics Robots in automobile production Situation: The robot in the automobile production runs 12 cycles/min. at a travel distance of 6.5 m and a power consumption of 10.7 kW. Fast cycles and large masses lead to excessive demands of the drive electronics and thus to unplanned failures. Solution: Use of three active energy management devices PXTFX, and three energy modules in the substructure, store the braking energy and, in case of need, feed it back in again. This not only leads to a stabilization of the...

Energizing Productivity Get it done right: Perfect sizing use our support! Any questions? PXTFX - PXTTerminal Make device and operating data visible! Connected to a PC via the connection cable PXTCC, the tool PXTTerminal visualizes the device parameters and in real time also the most important operating data of the application such as DC link voltage, storage voltage and the power. This operating data can be easily recorded and conveniently analyzed externally.

Digital type plate Via scan of the QR code, device-specific information is available if an Internet connection is available. For this purpose, management options for multiple devices are also available.

Energizing Productivity Just try it. Energy saving with PXTFX Support time according to power The time which a unit can support a given power with two kilojoules of energy can be read from the diagram. For x units, the support time is extended by x times. Support time with PXTFX without PXTFX Energy saving time Voltage curve of the DC Link Managing braking energy Power failure with PXTFX without PXTFX Power failure PXTFX plus PXTEX in case of „uninterruptible power supply“ Required energy (kJ) min.
