RS Americas, an industrial automation and electronics distributor, now affords variable pace drives (VSDs) for photo voltaic powered pumping purposes from Schneider Electrical, an automation expertise provider.
VSDs are energy conversion units designed to manage the pace, deceleration and torque of electrical motors with out the help of mechanical elements.
Schneider Electrical’s Altivar Photo voltaic ATV320 VSDs are purpose-built photo voltaic drives engineered to simply accept various DC provide voltages. Altivar Photo voltaic can adapt drive and motor efficiency to this variable energy with out the added tools, engineering and upkeep prices required to make use of commonplace VSDs with photo voltaic arrays, based on Schneider Electrical.
The businesses notice that commonplace VSDs are primarily designed to be used with regulated AC voltage provides. Due to this fact, if producers wish to use them with photo voltaic arrays that generate variable DC voltage, they should be paired with battery storage and an AC inverter which provides tools and upkeep prices.
Altivar Photo voltaic ATV320 VSDs are designed to help sustainable industrial operations, together with sprinklers; micro, drip and flood irrigation techniques; submersible, surface-mounted and water storage tank pumps; and off-grid, solar-powered water techniques and water therapy techniques.
In line with Schneider Electrical, the Altivar Photo voltaic ATV320 VSDs are suitable with a variety of pumps and photo voltaic arrays. They’re additionally suitable with synchronous, asynchronous and everlasting magnet motors, and use open-loop controls to regulate motor torque and pace management.
The VSDs help motor management strategies resembling:
- Sensorless vector management, which controls AC motor pace and torque with no bodily suggestions system.
- Commonplace V/f management, which maintains a continuing voltage-to-frequency ratio to manage motor pace.
- 5-point V/f management, permitting customers to outline a V/f curve with 5 or extra voltage and frequency factors to create customized relationships for purposes with high-inertia masses.
- Synchronous motor management, which adjusts energy provide voltage and frequency to exactly management motor pace and torque.
- Variable torque management, which adjusts the motor’s pace and torque based mostly on load calls for.
