| 2 | Repairing and Servicing of Variable Frequency Drive which shall be capable of operating on the AC Supply Voltages applicable to the end site with suitable tolerance for variations in the incoming mains power supply. The applicable supply voltage range must meet one the below: 380-480V A + 10%. VFD’s must be capable of continuous operation with the connected load with up to 3% voltage imbalance between the incoming phases. VFD’s shall be capable of operating with a mains supply frequency range of 50-60 Hz + 2%. The VFD shall be capable of variable frequency, variable voltage output in the range 0-50Hz and 0-45Hz Supply Voltage. VFD’s after repairing should include protection features to ensure that the motor may not operate in an overloaded condition which may cause damage to the connected motor. It shall be capable of controlling the motor with a constant or variable torque output characteristic in order to operate the desired load. Selection between constant and variable torque operation should be easily selectable by parameters within the VFD. (Make: ABB15KW Model No. ACS550-01-031A-4) |
| 3 | SITC of Variable Frequency Drive of following capacity which shall be capable of operating on the AC Supply Voltages applicable to the end site, with suitable tolerance for variations in the incoming mains power supply. The applicable supply voltage range must meet one of the below: -380 – 480 V AC ± 10%. VFD’s must be capable of continuous operation with the connected load with up to 3% voltage imbalance between the incoming phases. VFD’s shall be capable of operating with a mains supply frequency range of 50 – 60Hz ± 2%. The VFD shall be capable of variable frequency, variable voltage output in the range 0 – 50Hz and 0 –415 Supply Voltage. VFD’s must be available with a minimum IP20 rating and should include protection features to ensure that the motor may not operate in an overloaded condition which may cause damage to the connected motor. It shall be capable of controlling the motor with a constant or variable torque output characteristic in order to operate the desired load. Selection between constant and variable torque operation should be easily selectable by parameters within the VFD including removing of existing VFD, Programming & Synchronization of the software with the existing VFD modules for management of all parameters as running in existing case including buy back for old material (Make: ABB15KW Model No. ACS550-01-031A-4) |
