Automatic Electrical Control Panels and Variable Frequency Drives are two indispensable devices used for providing consistent supply of power to electrical and electronic instruments at required voltage speeds and electric current amounts.
One of the major obstacle on the production floor like power spikes and the resulting adverse impact thereon on production are eliminated by use of the automatic electrical control panels. No industrial process needs to be halted due to power blackout as power is shifted to a standby generator on a signal from this device. In addition to avoiding the adverse impact on production due to reduction in power factor it also ensures that no fine is levied by electricity board supplying electricity to the industrial application.
Several sizes and differing voltage capacities are being produced by the Automatic Electrical Control Panel manufacturers to suit the varied requirements of industrial applications. The different components that form a part of this equipment is a battery charger, power relays, electronic circuit and terminal blocks and they all together work to send a signal for the generator to resume at times of power blackout. All applications involving heavy pressure and high loads are served best with this device as it ensures the smooth running of the production flow during a power outage. Made from robust rust free steel material it guarantees reliable supply of power during variable load requirements and reverts to the main power by shutting down the generator on power resumption.
The installation of this device is done by expert technicians who choose a place that is free from moisture, dust or chemical contact. Some of its important applications are in the field of microprocessors, electrical installations, LT & HT factories, electrical industries and process controllers. Besides maintaining a reliable high power factor some other advantages offered by this device includes ease of use, high efficiency, corrosion resistance, minimizing harmonic current and acting as safeguard to the electrical equipment.
Variable Frequency Drives prove highly useful in applications where there are frequent voltage imbalances. It propels the electric motor by changing the voltage and frequency of its power supply. It also monitors the ramp-down and ramp-up of the motor during its stop or start respectively. This adjustment of motor speed results in energy savings and enhancement of system efficiencies which in turn leads to improving the working environment. Lifespan of machines are increased as mechanical stress is reduced. According to VFD dealers, a large part of its industrial applications lie in the field of pumps, fans and compressors. Its usefulness in driving diesel engines is always emphasized by diesel engine dealers.
With so many advantages offered by these devices it is but essential that adequate care is taken towards their maintenance. Facts with regard to their maintenance are explained by the Variable Frequency Drive dealers and the Automatic Electrical Control Panel manufacturers. They include protecting the equipment from dust, pests and with regard to connection control and insulation. Whatever be the application, it is necessary to follow the maintenance program rigorously if the devices have to function for long periods of time.
