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. Components and designs are sized for 100,000
hours MTBF
