AFC: Clean Bulk AC Source & Frequency Converter
Intepro Systems has partnered with Preen to bring you AC Power solutions
The AFC Series is an adjustable power source that utilizes double conversion to accept a variety of inputs and provide a fully adjustable (across operating range) clean sinusoidal output that shields your DUT from grid harmonics.
These products were designed to help customers with their end-of-line, burn-in or laboratory power needs.
The IGBT based AFC Series is available in a Single Phase (0.5-120kVA) or Three Phase (5-2000kVA) Output Model. The adjustable output voltage range is 5 - 300VL-N (8 – 520VL-L for 3 Phase Output).
The AFC also allows for custom higher voltage ranges (ex: 600VL-L) or lower voltage ranges with increased current. The AFC gives customers the ability to define their frequency range. Users can choose a specific band to work with and save cost.
Featured Benefits
- Single Phase Output 0.5-120kVA
- Three Phase Output 5-2000kVA
- Double conversion Galvanic isolation input to input, Clean Output, THD: <2% (optional for <1%)
- Selectable Output Frequency Band
