Efficiency refers to the ratio of the output power to the input power, and the power efficiency depends on the switching power line technology of the Power Supply. The higher the efficiency is, the smaller the power loss will be.
For example, the power of a load is 10W, since the power supply also needs power consumption, the efficiency represents how much energy is provided to the load, and 80% efficiency represents 10/0.8= 12.5w, of which 2.5w is the loss of the power supply. It can be seen that the higher the efficiency, the better.
The efficiency of APM AC Power Supply can reach 86% at 220Vac/50HZ input and 230Vac/50HZ full load output. Compared with other products in the market (the highest efficiency can only reach 70%-80%), APM power supply has obvious advantages in terms of efficiency.
The traditional power supply uses three-stage circuit (PFC+ isolated DC-DC conversion + inverter), while the APM AC power supply simplifies the circuit and integrates the isolated DC-DC conversion into PFC, forming a two-stage circuit, so the efficiency is guaranteed. High efficiency, for users, can save energy, in the long run can save electricity.
The power factor is the ratio of active power to apparent power, and refers to the cosine of the phase difference between voltage and current, which depends on the PFC technology of the power supply.
In the power supply, some current circulates in the circuit but does not transmit electric energy, so that the apparent power is not equal to the actual power, and then the power factor is derived.
APM AC power supply at 220Vac full load, the power factor can reach 0.98, compared with other products in the market (0.9-0.97) has advantages.
In the case of no load, the power factor decreases slightly, but still far ahead of the standard 0.7 of other competitors. With the increase of voltage and frequency, the power factor also increases, which has a huge advantage.
If the power factor is lower, the harmonic content in the current will be higher. It will pollute the power grid, destroy the balance of the power grid and increase the reactive power loss.
APM AC power supply adopts active PFC design to compensate the phase difference between voltage and current, so as to achieve a high power factor. It can save the capacity of power supply equipment and reduce the loss of the line, improve the utilization rate of the power grid, also ensure the life of the power supply.
In terms of input voltage, APM AC power supply can be started at 190-265Vac voltage and can run stably at 220V voltage of municipal power supply. Meanwhile, voltage fluctuations within this range will not affect the stability of APM power supply.
In addition, 500W/1000W can even start at 90-265Vac voltage, which covers a larger range than the input voltage range of GW(100/200Vac±10%,115/230Vac±15%), itech(220Vac±10%,110Vac±10%).
In terms of output, the output voltage is 300V and the gear position is 150V/300V/AUTO. The user can choose the appropriate gear position according to different output conditions. In terms of output current, no matter it is 500W/1000W/1500W, the output current can be unmatched by other products in the market, which can provide users with a wider range of measurement.
On the output frequency, APM AC source provides users with two choices, advanced version with output 1000HZ and professional version with output 1200HZ. It can not only meet the low frequency requirements of general commercial industry, but also can be used in aerospace, military and other high frequency applications, with a very wide range. The highest value of other products on the market can only reach 500HZ, far less than the 1000HZ of APM advanced version.
