Siemens 6SE7028-6EC85-0AA0

The 6SE7028-6EC85-0AA0 is a motion control common rectifier drive module made by Siemens. It is one of the biggest technological manufacturing companies and is known for its multiple innovations in automation, industry, energy, and healthcare solutions. It excels in creating advanced systems that enhance productivity and sustainability in motion control applications.

Technical Specifications:

The 6SE7028-6EC85-0AA0 drive needs to operate at a three-phase nominal AC input voltage from 380 to 460 V and requires an output voltage DC ranging from 510 to 620 V. Both input and output voltage holds a variation of about ±15% for desired working.

It works on a frequency of 46 to 64 Hz with an input current value of 74 A (AC), and for output, it consumes a nominal current of 86A for DC. Therefore, the overall average current rating of the drive becomes 78 A for output performance. Additionally, it can deal with a consistent minimum operational load of up to 240 seconds, known as base load time duration.

This drive has a power dissipation of 0.26 kW that helps to keep an optimal energy performance while maintaining efficiency. It requires an air cooling amount of 0.028 m3/s and has the capability to handle an excess current with an average of 117 A for desired output.

It is classified as size C and occupies a weight of 18 Kg. It measures 180 mm in width, 600 mm in height, and 350 mm in depth. This compact and robust design ensures easy integration in applications where various industrial setups require limited space.

Operational and Installation Parameters:

For installation purposes, a three-phase power supply feeds into the drive system. On the DC output side, it can support the connection of multiple inverters and a brake chopper. The combined rated currents of the connected inverters can surpass the common rectifier’s rated current.

The drive consisted of 40°C (104°F) ambient temperature for ratings of copper cables. Moreover, installation adjustments are required for temperatures above 40°C (104°F) and at altitudes exceeding 1000 meters for proper operation within the desired range.

Safety Precautions:

The equipment operates under high voltage conditions. Ensure all connections are made only after disconnecting the power. Due to the DC link capacitors in the connected drive, dangerous voltage remains present for 5 minutes just after power is isolated. So, it is important to wait for some time and don’t touch the drive.

When the unit is open, be cautious of exposed live components. Contactors and relays connected to the same power network or nearby should be equipped with surging protectors, such as RC networks, to prevent electrical hazards. Maintain proper safety measures before and during the operation of the drive.
