Schneider inverter Altivar 61

Schneider Electric frequency inverter Altivar 61 series is environmentally-friendly and energy-saving

The drive is designed to be environmentally-friendly:
- Energy saving with a reduction in energy consumption of 70 % for ventilation applications and 50 % for pumping applications
- Reduction of fluid losses in distribution networks
- Use of 80 % recyclable materials - the Altivar 61 drive conforms to environmental standard ISO 14040 which defines a critical analysis of the product's impact on the environment

Compliance with international standards and certifications
The Altivar 61 drive has been developed to meet the requirements of directives regarding the protection of the environment (RoHS, REACH, WEEE, etc.) as well as those of European Directives to obtain the e mark. The entire range is UL, CSA, DNV, C-Tick, NOM and GOST certified and conforms to international standards relating to electrical industrial control equipment IEC/EN 61800-2 and IEC/EN 61800-5-1. The need for electromagnetic compatibility was taken into account at the outset when designing the drive. The entire range conforms to international standard IEC/EN 61800-3. The Altivar 61 drive complies with the requirements of safety standards for applications in explosive atmospheres (ATEX)

An extensive range
The Altivar 61 range offers numerous variants to meet the requirements of applications in a wide variety of fields and in very harsh environments. With these variants, the Altivar 61 range offers ready-to-use or modular solutions that can adapt to your needs.
Its numerous and comprehensive options enable it to be adapted and incorporated into electrical installations, sophisticated control systems, infrastructures and building management systems. They also create significant energy savings and reduce line interference.

A specific option, the Active Front End, enables the Altivar 61 to be used in installations where particularly low harmonic levels are required. It also allows the Altivar 61 drive to operate on unstable line supplies.

Schneider Electric vfd Altivar 61 series for pumps has a wide range of applications

The Altivar 61 drive incorporates advanced functions for optimum efficiency in the majority of applications in the industrial or commercial buildings sector:
- Ventilation
- Air conditioning
- Air purification, smoke extraction
- Fluid management
- Pumping and booster stations
- Irrigation stations
- Off-shore drilling rigs

Advanced functions

The Altivar 61 drive meets stringent requirements due to its numerous integrated application functions, while helping ensure the reliability of equipment with its protection and safety functions.

Functions designed specifically for pump and fan applications
- Energy saving ratio, 2 or 5 point quadratic ratio
- Automatic catching a spinning load with speed detection
- Adaptation of current limiting according to speed
- Noise and resonance suppression due to the possibility of adjusting the switching frequency during operation up to 16 kHz depending on the rating and the possibility of making frequency skips
- Preset speeds b Integrated PID regulator with preset PID references and automatic/manual (Auto/Man.) mode
- Electricity and service hours meter
- Fluid absence detection, zero flow and limited flow detection
- Sleep function, wake-up function
- Customer settings with display of physical measurements (bar, I/s, °C, etc.)

Protection functions
- Motor and drive thermal protection, PTC thermal probe management
- Protection against overloads and overcurrents in continuous operation
- Machine mechanical protection via skip frequency function, output phase rotation
- Protection of the installation by means of underload, overload and zero flow detection
- Protection via management of multiple faults and configurable alarms

Safety functions
- Machine safety via the integrated Power Removal function This function stops the motor and helps preventing accidental restarts; it complies with machine safety standard ISO 1389-1, category 3 and the standard for functional safety IEC/EN 61508, SIL2 capability (safety control-signalling applied to processes and systems). This safety function means that the drive can be installed as part of the safety system for an Electrical/Electronic/Programmable Electronic control system relating to the safety of a machine or industrial process.
- Means of the forced operation function with configurable fault inhibiting, direction of operation and references help ensure installation safety.
