How to correctly observe the high-speed pulse of AC power supply problem
When AC power supplies measure high speed pulses with rise times and pulse widths of nanoseconds, it is necessary to prepare an AC power oscilloscope with a large band width and a large number of samples.28 2023-07 -
Common faults of the programmable DC power upper computer
The programmable DC power supply has three programming functions, step and gradient, which can be applied to a variety of test requirements. However, some engineers are used to using PC software, or some special testing requirements require a connection to the PC.26 2023-07 -
Ac power electronic load device convenient way to use
Under normal conditions, it is necessary to select the appropriate working mode according to the AC power supply test content. In the test of AC power supply, dc power supply, battery, DC-DC converter, etc., it is necessary to have a "virtual load" corresponding to the actual load (circuit) that consumes current.24 2023-07 -
How to select the AC power radiator
According to the power consumption, the thermal resistance between the connecting point and the shell, the thermal resistance between the shell and the radiator, the temperature of the connecting point of the AC power amplifier and the ambient temperature, the thermal resistance of the radiator is calculated.21 2023-07 -
Brief introduction to the working principle and function of electronic load
Electronic load is a "load" function implemented by electronic devices whose output ports conform to Ohm's law. In fact, the electronic load is a kind of device that allows the power tube to dissipate power and consume electricity by controlling the conduction of the internal power device MOSFET or transistor.12 2023-07 -
Simple analysis of parallel operation function of DC power supply
Dc power supply products with "parallel operation function, dc power supply via parallel connection (same type), can easily increase the output capacity, especially the" single control parallel operation ", it can be parallel set all the power, and through the equivalent of "machine tool".10 2023-07 -
Generator AC test electronic load is a good assistant for emergency backup power
At present, the electronic load as the core of the generator set test system has been widely recognized in the market, the demand is growing rapidly. In general, it is mainly due to the increasing demand for generating units in various industries and the scientific inspection and maintenance of generating units.06 2023-07 -
Outstanding application of AC electronic load
Ac electronic load built-in pure resistance load, inductive load and capacitance load. When the three-phase input voltage is not balanced, the AC resonance point can be precisely adjusted04 2023-07 -
Intelligent capacitive load is required for high power DC power supply detection
In the circuit with DC power supply as the output end, the filter capacitor is often connected in series to filter out the AC component of the current, making the DC power supply smoother and cleaner.30 2023-06 -
What problems should be paid attention to in the load test of diesel generator sets?
Safety first: When carrying out the load test, to ensure that safety measures are fully implemented, the operator must wear safety protective equipment, and unauthorized operation is strictly prohibited.28 2023-06
