In the work, it is necessary to consider the radiator selection of AC power amplifier. The power amplifier used has a very large capacity, with a current of 40A and a power of 400W.

Programmable DC power supply has the advantages of low voltage and large current, not only in the range of 0-10V, the maximum current up to 50kA, instantaneous current rise time is less than 5ms, less than 2ms, less than 1ms optional, very suitable for a variety of low voltage electrical testing requirements.

With the rapid development of power electronics, product development has higher requirements for programmable AC power supply, that is, programmable AC power supply with high precision, programmable, wide range and other advantages.

With the continuous development of electric vehicles, the demand for charging piles is increasing. In the past, the actual environment test method was usually used for the charging pile test. Now some manufacturers are also choosing electronic load test charging posts. However, during testing, engineers may encounter the following situations.

From October 26 to 28, 2023, the 8th World Oil and Gas Equipment Expo was held in Hainan International Convention and Exhibition Center.

Do not worry when the DC and AC power supplies are faulty. Some small problems can be solved simply by eliminating them. Previously, Xiaobian shared the fault caused by "insulation amplifier" and swing, today specifically said the ground line and ordinary line caused by the problem.

Programmable DC power supply High power DC power supply is used for battery discharge test. By setting appropriate load resistance, constant current discharge test can be performed. Here, if the load resistance value is set too low, the reverse voltage will be applied to the DC stable supply and no constant discharge will be possible.

When assembling HVDC power supply wire kits in many workshops, sometimes they don't pay much attention to it. This allows the high voltage DC power supply to be deployed unexpectedly during use, leaving the wires exposed. Such high-voltage DC power supplies are also very prone to failure. Then imagine, if you want to repair a machine, when you open the outer packing board and see a mess of wires, you must want to send the machine straight away, do not want to repair it. This is the function of the high voltage DC power supply wire kit.

ABC three-phase induced current and ABC three-phase capacitor current values are displayed directly on the control panel, and the resonant point symptoms are displayed directly on the panel.

Digital trigger different from analog trigger, DC and AC power supply digital trigger data directly using ADC sampling data. Therefore, the sampling and triggering units process the same data.
