DC Drives

Sai Automation make DC Drives are highly sophisticated and provided with adjustments which are factory set and may require only slight re-adjust at the time of commissioning.

The drive is supplied normally in two parts i.e. DC Drive panel & one Pendent box.

DC Drives has been specially designed, it must be installed in all area, where the following conditions exists:

• Ambient temperature does not exceed 45 0 C  & it is not less than 10 0C .
• Ambient air is reasonable clean & dry and must be free of flammable or combustible vapours, steam  or corrosive gases.
• Attitude should be 1000 meter above sea level maximum.
• The clearance around the cabinet must be enough to provide full accessibility to the front and back side. Also Provide a non-restricted airflow from the intake and exhaust ventilation lowers.

Features

• High speed fuses in the incoming lines for protection   of thyristors.
• di/dt protection
• dv/dt protection
• Surge suppressor across each thyristor
• Electronic single phase protection
• Electronic instantaneous over current trip
• Over temperature protection for thyristor
• Current sensing type field loss relay
