This ALTIVAR (Schneider Electric) is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
The ALTIVAR 28 (ATV28) adjustable frequency AC drive incorporates the latest sensorless flux vector technology in a compact design for three-phase asynchronous squirrel cage motors. This versatile drive offers increased performance while maintaining cost-effectiveness. The ATV28 provides advanced speed control capabilities for motors from 0.5–20 hp.
Industrial users and OEMs who specialize in small material handling, HVAC, pump, or general purpose motor control applications will find the ALTIVAR 28 drive well suited for their use.
• Advanced design, simplified construction
• Reduced parts count and fewer internal electrical connections
• Conforms to/meets international standards
• Features/functions meet requirements of most applications
— simple machines — conveyors
— packaging SFVC
• Integrated/on-board four-button, four to seven segment character display control
• Compact design reduces valuable panel space
• Provides an economical solution for communication capability for networking mini-drives into a system
• Analog output provides a simple, built-in speed indication signal that drives a remote meter while eliminating the expense of auxiliary signal devices
• The assignment of a logic input to fault reset and the automatic restart parameter minimize downtime.
The ATV28 family of adjustable frequency AC drive controllers is used for controlling three-phase asynchronous motors ranging from:
• 0.5–3 hp (0.37–2.2 kW) 208/230/240 V, single-phase input
• 5–10 hp (3–7.5 kW) 208/230/240 V, three-phase input
• 1–20 hp (0.75–15 kW) 400/460/480 V, three-phase input
• 1–20 hp (0.75–15 kW) 525/575/600 V, three-phase input
Operator interfaces, configuration tools, and communication options are shared throughout the product range.
The ATV28 drive controller uses the latest in AC drive technology. Intelligent power modules (IPMs) are used on the entire product family. The IPMs contain IGBTs (insulated gate bi-polar transistors) to produce a pulse width modulated (PWM) output waveform to the motor. IPMs minimize part count and improve reliability.
The ATV28 drive controller integrates third-generation sensorless flux vector control for three-phase asynchronous squirrel cage AC motors. This allows the drive controller to deliver needed torque with excellent dynamic response over a wide speed range.
ATV28 drive controllers are capable of:
• producing a transient maximum current of 150% of nominal drive controller current for 60 s
• output frequency ranges from 0.5–400 Hz
• 30% of nominal motor torque without dynamic braking (typical value); up to 150% with optional dynamic braking resistor
• switching frequency adjustments from 2–15 kHz
• drive controller protection through galvanic isolation between power and control (power supplies, inputs, and outputs)
• Protection against short circuits:
— in available internal sources
— between output phases
— between output phases and ground for 7.5–20 hp drive controllers
• thermal protection against overheating and overcurrents
• undervoltage and overvoltage faults
• overbraking fault
• thermal motor protection integrated in the drive controller by calculation of I2t
ATV28 drive controllers rated at 230 V and 460 V are available with an integrated EMC filter. This filter reduces conducted and radiated emissions, and complies with IEC product standards IEC 61800-3 and EN 61800-3 for drive controllers. Compliance with these standards meets the Class A requirements of the European directive on EMC.
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).
