RTV84D16Q - Speed Controller - TELEMECANIQUE
This RTV84D16Q reference drive and TELEMECANIQUE brand is a variator of the RECTIVAR 4 series 74-84 series.
Three phase. 50 / 60Hz.U: 380/415 / 440V, Imax: 16A
This TELEMECANIQUE speed controller is at your disposal to replace your defective equipment and has a suitable guarantee.
The RECTIVAR RTV-74 32 to 3000 A single bridge three phase variable speed controllers are designed for speed regulation of 6 to 1700 kW DC motors, with separate excitation.
The RECTIVAR RTV-84 16 to 3000 A double bridge three phase variable speed controllers are designed for the speed regulation of 2,7 to 1300 kW DC motors with separate excitation.
Both series are supplied from an AC three phase mains.
The RTV-74 speed controllers enable operation in quadrants 1 and 4 or 2 and 3 of the torque/ speed range.
The RTV-84 speed controllers enable operation in all 4 quadrants of the torque/speed range.
From the 800 A rating upwards, both series are fitted with a field current regulator.
The RECTIVAR 74/84 includes for each one of the series :
- 7 compact technology ratings from 32 to 650A, rating 16A is only available in RTV-84
- 4 modular technology ratings from 800 to 3000A.
• Compact technology combines in the same metal enclosure :
- the power part, with a 6 or 12 thyristor bridge and the thyristor protections, the control transformer, a power interface board and its daughter board in the case of the 12 thyristor bridge, a galvanic isolation board, the current transformers and the fans, if necessary
- the control rack, located at the front of the speed controller on the 8 ratings, includes the microprocessor board, the display board and a dialogue keypad on the protective cover.
• The modular technology includes a power chassis and a control module connected by a set of 2 metre long, sleeved screened cables.
- The power chassis includes : a 6 or 12 thyristor bridge with the thyristor protections, the firing circuits, the control transformer, the thyristor protection fuses and the fan with its safety devices.
- The module known as the control module : identical for all 4 ratings, includes :
- the thyristor excitation bridge
- the excitation current sensor
- the excitation control board
- the control transformers
- the power interface board
- the galvanic isolation board
- the control rack, identical to the one described above, located on the front.
For both technologies, the control rack, mounted on hinges, can pivot, enabling access to the part at the back.
The control is completely isolated from the power part, the maximum voltage being 24 volts DC.
Since its creation, the Telemecanique brand has been pursuing an innovation policy, which has become one of the world’s first references in automatism management.
The story of Telemécanique is read through that of its inventions, initiated with the launch of the first contactor on bars. A patent filed the same year of its acquisition, in 1924! It will develop contactors D became world reference. The 1980s marked the acquisition of Telemechanics by Schneider Electric (1988).
