![Frequency Inverter [L300 series]](https://img2.exportersindia.com/product_images/bc-full/dir_16/465834/l300-series-1523345074-3773038.gif "Frequency Inverter [L300 series]")
Frequency Invertor L300 series :-
A central goal of Hitachi's development work on the L300P series: To achieve optimum economical efficiency for standard V/f-applications. The result is an inverter that is among the smallest of its class. In a compact housing, the L300P integrates a wide range of standard features. For instance, a unique power supply control for improved CE-EMC characteristics, PID control for automatic control of important process parameters, an auto-energy saving mode for optimal energy efficiency, to name only a few.
These features make the L300P the inverter of choice for all applications which call for maximum reliability: for fans and pumps, heating and air-conditioning and all process engineering tasks related to flow control.

![Frequency Inverter [SJ - 300 series]](https://img2.exportersindia.com/product_images/bc-full/dir_16/465834/sj-300-series-1523344438-3773008.gif "Frequency Inverter [SJ - 300 series]")
Frequency Invertor [SJ - 300 series] OverView :-
| The new SJ300 Inverter are among the most powerful of their class. Hitachi's unique "Advanced Sensorless Vector Control" (ASLV; patent pending) offers 200% starting torque and full torque at zero Hz – without feedback. The integrated Hitachi 32-bit SuperH RISC processor delivers the dynamic response needed for high-end applications. To compensate possible temperature fluctuations within the motor, which might adversely affect smooth control of the motor, an online/offline motor-autotuning function is included. A newly developed internal control process leads to drastically reduce any rotational fluctuation at low speed, which enhances process stability and precision.
