Intermediate Frequency AC Power Supplies The IFP series is AC Power Supplies with a constant 400Hz output frequency and adjustable output voltage, based on the same technical principle as the adjustable AC power supplies of SPWM method, IGBT module design and D/A conversion technology. The difference is that the output frequency of the Intermediate Frequency AC Power Supplies is constant at 400 Hz, it is a replacement product of unit type variable frequency power supplies with higher output frequency accuracy and stability.

Computer power amplifier equipment requirements:
The computer needs to have an audio output interface (very common is an external headset, audio interface), the power amplifier needs to have an audio input interface (mostly this interface, most of the RCA Lotus interface)
Wires needed for computer power amplifiers:
A computer headset 3.5 to RCA audio cable (because of the impact of its own computer output audio, the proposed audio cable should not be too long, the quality may affect the sound quality, after amplifier amplification, the line current noise will be large).
Computer power amplifier method: 
Insert the 3.5mm plug of the audio cable into the computer-related 3.5mm AUDIO OUT or headphone jack, and insert the RCA plug at the other end into the AUDIO IN of the corresponding amplifier.
The output power of single-phase Intermediate Frequency AC Power Supplies ranges from 500VA to 200KVA, and the output power of three-phase Intermediate Frequency AC Power Supplies ranges from 3KVA to 600KVA. The output voltage of both types can be divided into 0 ~ 150Vac, 150 ~ 300Vac with 400Hz fixed output frequency. This series of AC power supplies are featured for high precision, stable output, high display resolution, low waveform distortion and complete protection functions.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies, Currently, the Intermediate Frequency AC Power Supplies are mainly used for aircraft and mechanical equipment, radar, navigation and other military electronic equipment and other occasions that require 400Hz intermediate frequency output.
How to connect the amplifier to the computer? Amplifier connection computer requirements
Amplifiers may not always be used to connect audio equipment, and amplifiers can be connected to computers. So how does the amplifier connect to a computer? The writer today came to a detailed analysis of how the amplifier connects to computers and connection requirements.
