Compact 400Hz for Laboratory or Production Line:
Series RBC4000 static frequency converters have been designed for continuous duty operation in production line or laboratory applications. They will provide a high quality 3-phase, 400Hz output from almost any 50 or 60Hz utility supply, even if this supply is only single phase. The converter output is 4-wire, sinusoidal, highly regulated and galvanically isolated from the input.

Variable Frequency and Voltage Option:
As part of the testing of avionics and other aircraft equipment it is often required to vary the supply voltage and frequency in order to simulate the worst case supply quality that might be found onboard a real aircraft. Thus RBC4000 models may be ordered with control knobs that will continuously vary the output frequency from 380Hz to 420Hz and the output voltage from 97V to 132V (line to neutral). In addition, preset variations of 400Hz +/- 5% and 115V +/- 10% may be triggered by a remote PLC for automatic testing.

Only a Single Phase Supply Available? No Problem:
RBC4000 models operate as standard from a single phase supply whilst giving a 3-phase output. Both models will
operate directly from a standard European 16A (230V) supply or a UK 13A supply (the 4KVA is slightly limited on maximum power). Equally in North America a 32A, 115V, (60Hz) supply may used.

Unity Input Power Factor:
Both RBC4000 models have a power factor corrected input. This means that input power consumption is minimised and overall efficiency is maximised. This is particularly important when a limited single phase supply is being used to power the converter.

Sophisticated Digital Display:
An LCD display gives accurate information on all the major output parameters. These include output voltage (L-L and L-N), current, frequency, power factor, Kw and KVA. Each parameter may be displayed for each phase.

High Reliability IGBT Inverter:
RBC4000 units use a highly reliable IGBT based output inverter which is not only very quiet in operation, but is also able to tolerate extremely non-linear load types. Phase unbalances of up to 100% present no difficulty and the inverter has been dimensioned to withstand very large transient overloads, so that equipment with high start-up currents should rarely present a problem.
