Delta AFE2000 model

Active Font End (AFE) is a controllable rectifier with features such as bi-directional power exchange between AC and DC and power recovery. (Regenerating usable power) that can be recycled into the main electrical source to reduce electrical energy costs. AFE uses pulse modulation according to the wave width (PWM modulation) to help reduce high current peaks (Distinctive peaks) and help make the periodic sine wave range the best (Perfect sine). The electrical factor that can be adjusted the most is 1 – the ratio between the load capacity and capacity is 1:1. In addition, AFE eliminates high order harmonic currents. This results in very low harmonic current values ​​(THD (harmonic distortion) less than 5%) while improving the power factor. This makes it possible to save costs in purchasing tools to further improve power quality. AFE also helps stabilize power quality so that it is not affected by power ripples from the mains power source and can be applied in series connections.

• Saves energy with AC/DC dual power control system and adjusts the power factor as much as possible. 99% • Use a new braking resistor instead of the old one to help save costs. Space and energy saving • Pulse amplitude modulation control system (PWM modulation) greatly reduces harmonic current peaks and helps optimize the periodic sine wave current (Perfect sine wave current). • Complies with IEEE STD.519-1992 standard to keep harmonic current distortion less than 5%. • The DC bus voltage is constant so it is not affected by voltage ripples from the mains power source.
