FUNCTION
With a current load capacity of 5 amperes effective continuous and 40 amperes peak for 3 seconds compared to the storage unit, which may have a maximum voltage of 450 volts DC, the PxtTX device can generate up to 18 kilowatts of power. The device has a closed housing to provide special protection against suspended particles in the air. Heat is dissipated by convection via heat sinks.

The device can be equipped ex works with a storage volume of two or four kilowatt seconds. Built into the device as standard is the automatic detection of the brake transistor switch-on voltage threshold, which enables the device to work with all commercially available frequency inverters and servo controllers in a plug play manner. The extensive safety features of the PxtTX protect against reverse polarity of the DC link connections, against the connection of loaded memories and against overloading the system on both the memory and DC link sides. Internal fuses are standard.

The PxtTX device is equipped with an SD memory card, an external 24-volt power supply, status indicators via LEDs, boot loading and reset options and 6 digital I/Os. This is supplemented by output functions via a USB module.

BENEFITS
The main application is that of a short-term UPS for electrical drives in an environment with suspended particles in the air. The device is specially protected against this with a closed housing and convection heat dissipation.

The main area of application of the PxtTX is the compensation of so-called brownouts, i.e. the bridging of short voltage dips as well as the safe and defined standstill of the electrical drive system during blackouts.
