400Hz 40Kva Static Frequency Converters : RP05500/28

Description

Powervamp converters stand alongside those of the world’s leading manufacturers in quality and performance, with a superb reputation when it comes to product reliability, support and service. Unlike converters derived from 50/60Hz systems, Powervamp units are designed from conception to operate continuously at the demanding 400Hz frequency. Powervamp converter reliability starts with Powervamp’s software design team and full in-house manufacturing with intensive quality control – from initial design to finished product. The full range of converters, from 30 to 90kVA, is supported worldwide by the company’s Technical Services Department and team of skilled graduate engineers, covering technical issues from power requirement and architects’ drawings to installation and service contracts. Housed in IP65 cabinets as standard, Powervamp converters use forced airflow with oversized heat sinking to maintain a stable temperature of the power electronics, crucial to the maintaining of continuous output at maximum load. Integral input and output EMC filters guarantee minimum distortion from the mains supply. Top wave form quality ensures compliance with the tight sine wave demands of modern aircraft. Where operators require both AC and DC power, Powervamp offers a separate stand-alone module which gives operators the flexibility to move the DC unit to different aircraft stands. For hangar installation, an integral unit is available. A PFC rectifier converts three-phase into DC, with the PWM (Pulse-Width Modulation) inverter switching the DC back to AC at 115/200V 400Hz. The output transformer provides galvanic isolation between the input and the output. The 28V DC module can be directly coupled to the GPU 400Hz output through an adaptor plate thereby minimising investment costs. Powervamp converters utilise electronic rectifiers with power factor correction to ensure that current drawn from the mains is perfectly in phase with the voltage (0.99pF @ full load), giving high efficiency compared to non PF corrected systems. Converters are designed for continuous operation at full load with the microprocessor controlled PWM IGBT inverter sized to accept high overload.
