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.

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.

Electric current can cause various injuries to the human body. When current passes through the body, it can result in electric shocks, burns, or even more severe damage. The energy from the current may be converted into heat, causing burns, or it may affect the nervous system, leading to muscle contractions or even cardiac arrest.
One of the most dangerous effects of electric shock is that it often occurs without warning. The damage happens rapidly, making it difficult for the body to respond. This sudden impact increases the risk of serious injury or death.
Electric shocks occur when current flows through the body, stimulating tissues and causing involuntary muscle contractions. Severe cases can disrupt heart function, breathing, and even lead to life-threatening conditions. A current of just 50 mA can be fatal, especially if it passes through vital organs like the heart or lungs.
In addition to electric shocks, electrical injuries can also occur due to thermal, chemical, or mechanical effects. These injuries are often visible on the skin but can cause deep tissue damage. Common types include electric burns, skin metallization, and eye injuries caused by arc discharge.
The severity of the injury depends on factors such as the current's strength, duration, path through the body, and frequency. For example, alternating current (AC) between 25–300 Hz is more dangerous than direct current (DC). Women and children are generally more vulnerable due to differences in body resistance and sensitivity.
Body resistance plays a key role in determining how much current enters the body. Dry skin has higher resistance, while wet or damaged skin reduces resistance, increasing the risk of harm. Prolonged exposure to current can lead to increased damage, as sweating or other factors lower resistance further.
Understanding these risks helps in developing safety measures and protective equipment. It's crucial to minimize exposure to high currents and ensure proper insulation and grounding in electrical systems.
Figure 1 illustrates the effect of current on the human body based on its amplitude and duration. Different zones represent varying levels of harm, from harmless sensations to life-threatening conditions.
Overall, electric current poses significant dangers, and awareness of its effects is essential for preventing injuries and saving lives.
