With the development of technology, more and more power electronic products are able to operate under DC + AC input conditions, which are not supported by all power supply in the market. However, APM technologies AC power supply can realize seamless AC to DC switching and provide AC + DC output mode, which not only shortens the AC to DC conversion period, but also reduces the loss and improves the energy efficiency.
● High speed DSP+CPLD control, high frequency PWM power technology, high output efficiency Adopt the current high-end power supply DSP + CPLD control technology, strengthen the internal data and logic operation ability, and control faster, product operation more stable. Quickly set and read various waveforms, generate harmonic analysis, and support remote software upgrade and update.
● Built in power meter can measure 15 electrical parameters such as voltage, current and frequency A high-precision power meter is built in the APM technologies AC power Source, which can accurately and quickly view the real-time data of each parameter during the test, so as to easily grasp the condition of the tested object, without the need to build complex lines and additional power meters, thus saving the test time and equipment cost. It can measure and define sequence voltage, current, active power, reactive power, apparent power, surge current, etc.
● Settable ON/OFF Phase angle of Output Waveform and slew rate The ON / OFF phase angle of the waveform can be set, with the setting range of 0-359.9 °. This setting is very flexible, which can carry out the verification test of the start-up surge current of on / off, and can also set the rise and fall slew rate of the voltage and frequency, so that the voltage changes slowly, which is used to start the inductive or capacitive load with large capacity, so as to avoid the excessive current generated by the instantaneous start, leading to the interruption of the triggering protection. As shown in the figure, 90 ° phase angle is set to start and the voltage changes slowly.
● Output simulation sequence and Power Line Disturbance Simulation It has powerful functions to support simulation of AC power grid interference, supports list / pulse / step mode, simple time setting and cycle setting, and is suitable for Power Line Disturbance Simulation.
(1)List mode: users can edit the sequence file to output as they wish, set the start waveform parameters, end waveform parameters, take time / period as the standard, total steps, execution times, etc., and save the sequence for quick recall.
(2) Step mode: The user can set the voltage slow change by setting the initial value, phase angle, step voltage value, start / end frequency, step time, etc. The voltage starts slowly, which can avoid the excessive current generated by the start, and can be used to start large capacitive or inductive loads.
(3)Pulse mode: Users can edit special pulse voltage waveform to output. By setting pulse waveform parameters, duty cycle, phase angle, cycle length, etc., the product can be tested in production, and the actual application environment simulated, so as to find product quality problems faster.
APM technologies wide range and high performance programmable AC power supply is a universal and powerful programmable power supply, which can be used as a part of every electronic design or production test. This series supports constant current(CC) output mode, can simulate any waveform output, with waveform preview, intuitively display the required voltage waveform, also built-in rich waveform database, built-in test waveform meeting IEC level standards can also be directly quick recall, and provide user mode to define the output parameters, which can be edited by users themselves, and can be completed by setting parameters The variation and repetition of voltage amplitude and frequency can meet various demands in the electronic field.
