Thyristor speed controllers

A thyristor speed controller of a throttle electric drive (DRS) is designed to provide reduced speeds of machinery equipped with slip-ring induction motors and throttles to limit currents in starting and braking modes.

The speed controller provides smooth or step speed regulation (determined by external connection at the Customer's site).

The speed controller with the starting throttle is designed to equip new variable speed drives or to replace cabinets with resistors and contactors in the rotor circuit in modernized electric drives.

Speed ​​control range is not less than 5.

The speed controller is produced in two types:

• a single block controller
• a double block controller

Speed ​​regulators are designed for operation at:

• Ambient temperature from - 40 ° С to + 45 ° С
• Relative humidity not more than 98% (U2 operating conditions according to GOST 15150-69)

The speed controller can be installed in places with mechanical vibration from 0.1 to 100 Hz and acceleration up to 20 m / s2 (M25 in accordance with GOST 17516.1-90).

Duty factor 60%.

The speed controller works only with the DDP choke in the rotor circuit.
