FREQUENCY INVERTERS

Our inverters are based on the latest state of the art technology in combining advanced mathematical techniques with the use of up-to-date industrial processors and high quality power electronics components.

We use the advanced mathematical techniques to produce PWM waves with complete symmetrical 3phase voltage wave forms mathematically optimized to arbitrary eliminate any number of Harmonics based on the switching frequency. Therefore, the harmonics produced in our inverters at low switching frequencies (as low as 2KHz) are far less than other top grade inverters with switching frequencies operating at 12kHz.

Our inverters can be supplied with special PWM harmonic elimination waveforms customized to meet the customer's special needs such as demanding high efficiency systems with harmonic spectrum to match special types of motor windings and/or to produce a defined output torque behavior from vibration, holding torque…etc. Due to our use of such advanced technology, our inverter can be used as a general purpose inverter in the control of CNC machines, and it represents one of the most cost effective inverters on the market.

Furthermore our INVERTERS  can be used extensively in Solar energy systems for providing Electricity supply networks single & 3-Ph. for various Domestic and Industrial applications

The advanced industrial processor provided within the inverter is used to store and manage the look-up table of the mathematically produced PWM waveforms, and also used to program the required operational Parameters such as:

- Changing the speed by the operator (via a user friendly interface) or via remote input signals    (digital or analog).

- Acceleration and Deceleration parameters.

- Defining a programmed output response curve.

The best power electronics components are used by us to manufacture high reliable inverter hardware, and all the units are provided as standard with the following features:

- Short circuit protection.

- Light output filter to eliminate the cable ringing when non-shielded Cables are used.

- Over load protection .

- Over heating protection.

-Withstand sustained 150% over load for 1 Min.

The inverter units are produced for any KW from 3KW up to 250KW 380volts (in ranges) as standard units, and also in customized configuration within any kW range to match customer’s special needs.

Our price lists for the KW ranges of the units are available upon request
