60Hz to 400Hz FREQUENCY CHANGER

The SPC6-1500 and SPC6-1501 are frequency changers that utilize switchmode technology to enhance product performance.  Advanced design elements utilized in these frequency changers are as follows:

Power Input Coupling Circuit:

This circuit has two major functions; it boosts the input voltage so that normal operation is achieved when the input varies from 105 to 240 VAC and controls the input current waveform such that it closely resembles the input voltage waveform (meets IEC Specification 555-2, Class A.) This is in contrast with conventional power supplies which draw large magnitudes of current during peak amplitudes of the input voltage waveform.

DC To DC Converter:

This circuit uses an isolation transformer to couple energy from the input circuit to the output inverter. This completely isolates the output power from the input power line.

Output Inverter:

Model SPC6-1500: The output consists of two inverters which are connected in series for the 0 to 260 VAC operating range and in parallel for the 0 to 130 VAC operating range. Separate output terminals are provided in order to minimize the possibility of incorrect external connections (ie. 130 VAC load connected to a 260 VAC output).

The SPC6-1500 and SPC6-1501 are designed for use on test benches to check radars, compasses, gyros and other navigation equipment where regulated voltage and frequency are required.
