Amtech Electronics (india) Ltd. - Our Products

We provide the efficient Active Front End Converter, which improves the quality of the power and prevents power pollution and voltage distortion that happen due to the use of non-linear equipment. Being one of the prime Manufacturers, Importers, and Exporters of cutting edge Active Front End Converter in India, we provide it at reasonable prices.

Range

• 11KW to 1000KW

Effects of power pollution

• Over voltage / current in the distribution network
• Over heated power cables due to skin effect and copper and iron loss in transformers, motors and generators
• Overheating in all types of electronics systems causing components failures
• Nuisance tripping in circuit breakers and protection relays
• Malfunction of automatic control systems
• Damage to capacitors due to resonance
• Inaccuracy of instrument measurement
• Interference in telecommunications systems
• Voltage distortion and lagging in power factor

Mitigation of Harmonics

Wherever there is a 6-pulse rectifier at the input of variable frequency drive, UPS or there is a 6- pulse rectifier supplying the common link to which number of variable frequency drives are connected, the input harmonic distortion of current is 62%. Due to presence of harmonics the effective power factor (which is a product of displacement factor and distortion factor) is less (of the order of 0.8). If variable frequency drives has regenerative load like centrifuge or lift lot of power is dissipated in dynamic braking across the DC link. Active front end converter (AFC) can take care of these three problems in totality due to its capacity to work in four quadrants.

• It reduces the total harmonic distortion of input current to less than 5%
• It can improve the input power factor up to unity
• It can feed back the regenerative power to mains so that energy can be conserved

Amtech's Axpert-AFC Active Front End Converter offers all these advantages and can serve many applications such as :

• Countermeasure for power source harmonic wave
• Water & drainage works, cable car, lift, blower etc
• Power source regeneration
• Kinds of tester, crane, elevator, centrifugal separator, kinds of line drive etc
• Common converter
• Kinds of line drive, rotary press of news paper etc
