New generation of battery chargers

Our new generation of battery chargers CRFD was designed to bring you more innovation while maintaining the performance of the previous range.

11 positions depending on battery technology (Sealed lead, lead acid, AGM, Gel, etc.)

Additional information deported for batteries and charging status

Additional terminals for connecting an external load balancer for adding with extra batteries

High performance level

Function "balancing current" (mounting in parallel) up to 6 chargers

Extended powers range of chargers

DC power set

These new devices are the result of a research and development by our company, to have maximum reliability and performance in the field of energy supply systems. We have not chosen to implement only the traditional energy conversion systems (isolating transformer with a thyristor), but to liaise flexibility and the advance of a digital logic to a microcontroller.

The electronic controls of the RCRFn rectifiers are reliable and increase the life of batteries.

Aunilec proposal

Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage “optimisation” devices have a fixed voltage adjustment, others electronically regulate the voltage automatically. Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply. Overvoltage leads to sites using more electricity than needed, and as a result incurring higher electricity bills. The overvoltage is not only costly but can also be detrimental to equipment.  Excess voltage produces additional noise, heat and vibration, causing stress on internal parts - especially to motors which are vulnerable to overheating and wear out more quickly. Aunilec EcoREG voltage optimisation system ensures that a building only receives and pays for the voltage that it actually needs, and no more.Aunilec EcoREG Voltage Optimisers are available in power rating from 15 to 2600 kVA, single-phase and three-phase versions.

Highest level of protection

Line conditioners have been designed to provide the highest level of protection to electrical appliances connected to distribution lines disturbed by sudden voltage variations, HF noises and spikes.  Statistically, these phenomena represent more than 95% of electric anomalies that could be the cause of breakdowns and poor operation of any kind of appliance connected to distribution lines.

Power factor correction in presence of harmonics

In recent years, Power Factor Correction has evolved greatly due to the presence of generated harmonics by the loads. 

These loads produce harmonic currents and voltage which distorts the network waveforms. The main sources of harmonics are generated by AC/DC static converters and UPS systems. For these reasons it is essential that any installation of Power Factor Correction equipment must be carefully evaluated. 

The possible presence of harmonic currents in the network could create conditions of parallel resonance between the inductance of the network and the capacitors, generating overcurrents and overvoltages, which would cause premature failure of the power factor correction capacitors. The ideal power factor correction solution for any system must be determined by examination of the system parameters and harmonic spectrum.

Capacitor bank without regulation known as fixed compensation

Used when reactive power to compensate is constant and when the load is working 24h / 24h.

Used when reactive power is to compensate for low power. Also standardized by the coefficient QC (Compensation to install in KVAR) / SN (Transformer power in KVA) is generally <15%. This threshold of 15% is indicative and we recommend it to avoid to overcompensate the charge power vacuum.

Used to directly compensate the asynchronous motor, load losses of the line head transformer.

Static power factor correction capacitor

The reactive power regulator has a switching time of the banks extremely quicker than the standard regulator. The device for switching the capacitors banks is electronic, controlled by thyristors, with the capability of switching the capacitors at zero crossing. Maximum speed in switching the capacitors banks (the total power is switched in less than one second). No current peak on the capacitors at the time of switching of the banks. No voltage peak on the capacitors at the time of switching off the banks. Elimination of problems related to contactor contact wear.

Active filtering and power quality

FAFW is the new generation of active harmonic filters. It reliably mitigates harmonics and compensates voltage dips as well as reactive power. The FAFW analizes network disturbances and provides an opposing compensation current. In doing so, FAFW actively adapts to fluctuations and responds in less than half a millisecond. Its compact dimensions, simple installation, and digital intelligence allow for a quick and straight forward integration in the most diverse applications.

These products allows to reinject a current corresponding to the total harmonic component (the first order). By this way, the network is traversed by a current equal to the single fundamental component.
