Options Description
Copper transformer Copper bus is the material used for transformer windings. Transformer parameters and efficiency are commensurable with the basic type of transformer with windings of aluminum busbars
Mechanical bypass of power cells Bypass of each power cell of the drive is made on the basis of a vacuum chamber, with a response time of not more than 4 msec
IGBT bypass of power cells Bypass of each power cell of the drive made on the basis of IGBT transistors
Additional power cell in each phase For compensating voltage drop on the output sine-filter or reactors (if available) and the long cable line, as well as to ensure operation in the nominal mode in the case of bypassing the cells (with this option)
Increased protection degree Enclosure IP42
Increased operating temperature Maximum operating temperature up to +50 °С
Top cable entry Organization of terminals for entry power and signal cables on top of AT27 VFD
Heating system Build-in option. Minimum operating temperature from minus 10 °С
Redundant cooling fans Additional cooling fans with a check valve system to ensure AT27 operation with rated power if one of them fails
Additional PCB coverage Coating of printed circuit boards with a special varnish to protect against aggressive impurities in the air
Electromagnetic door lock Electromagnetic locks on the doors of the AT27 power compartments provide protection against opening doors when medium voltage is applied
Profibus communication protocol Convertor Modbus-Profibus
CB27 Switch Cabinets External cabinets. Allow you to implement the required one-line diagram
Reactors for transfer of the motor to mains External cabinet. Designed to provide synchronous and shockless transfer of the motor to mains.
Sine-filter External cabinet. Designed to improve the output current and voltage THD, as well as reduce the value of the parameter dV/dt.
