Absopulse Electronics Intros VFC501 AC Power Source
Absopulse Electronics Ltd. (Carp, ON) announced its new VFC501 variable ac power source, which delivers 500VA of power at any frequency in the range of 47Hz to 424Hz, with the output continuously adjustable from 0Vac to 250Vac. The VFC501 is suitable for use in a diverse range of industrial, engineering, academic and laboratory applications, including the simulation of voltage and frequency deviations for equipment under development, quality control, safety approval, testing and verifying operation of electrical equipment for export markets. The unit can also be used as an ac frequency converter.
The unit accepts inputs of 115Vac or 230Vac ±20 percent auto-ranging at 47Hz to 440Hz. "Hot" push buttons with auto-stepping on the front-panel allow for precise, quick voltage and frequency adjustment; and four additional controls allow for frequency selection at 50Hz, 100Hz, 200Hz or 400Hz at the touch of a button. The VFC501 utilizes pulse-width modulation technology to synthesize a precision regulated sinusoidal output with less than five percent total harmonic distortion at full load, and a frequency stability of ±0.1 percent. The output is fully isolated from the input and may either be used in floating mode or in grounded neutral operation. The unit features full electronic protection, high efficiency and very low output noise. It is fan-cooled and rated for operation over a 0°C to 50°C temperature range.
The VFC501 is designed to meet international safety approvals including IEC950, CSA22-2-950 and UL1950. Both ac input and output are highly filtered and meet the requirements for EN55022 Class B EMI emissions. Housed in an 8.5in x 5.1in x 14in enclosed case, the unit weighs just over 4kg (9lbs). Customized versions of the power supply are also available. The VFC501 is priced at $1,350 in quantities of one to four.
