Product Introduction

The ASR-2000 series power supplies feature a wide input voltage range and excellent voltage stability, capable of precisely outputting various voltages and currents to meet different power needs. Perfect combination of function and size The ASR-2000 series (AC + DC) power supplies are designed to be smaller (Full Rack width) compared to competitors such as Keysight AC6801 and Chroma 61501. Under the same 500VA specification, Goodwill Electronics' ASR2000 series only requires half the Space (1/2 Rack). Traditional AC power supplies have two tasks: The first task is to simulate the AC voltage and frequency range of global mains or special environments: As a universal adapter, the rated input voltage is AC 100~240V; the operating voltage range is AC 90~264V; the rated frequency is 50/60Hz±3Hz. The power frequency of aviation/aerospace equipment is 400Hz±20%, and the primary function of the AC power supply is to simulate the operating range under these environmental conditions. The second task is to provide simulations of anomalies: For example, the inrush current (Inrush current) can be quantified quickly; in the past, the method of confirming the maximum inrush current was very time-consuming, and the AC power supply had to be turned on and off repeatedly while capturing the transient inrush current (Inrush current) through an oscilloscope. , now through the designated phase start/stop function that comes standard with the ASR2000 series, you can set the start (or stop) phase at 90° phase angle or 270° phase angle, because these two phase angles have the highest voltage, and the highest voltage Turning on and off will cause the maximum instantaneous current. Coupled with the I-peak measurement function, you can see the measurement value of the inrush current (Inrush current) on the large screen of the ASR2000 without connecting an oscilloscope and current probe. Solve complex measurement tasks in the past. The arbitrary waveform function can simulate waveforms with poor power quality, such as: sudden voltage rise; instantaneous pulse; voltage sag; voltage change; frequency change, etc. The test waveforms in the automotive electronics ISO-16750 standard are also generated through arbitrary waveforms function to edit. Finally, let’s talk about why the AC power supply needs to have a DC output mode. For applications that require rapid changes in DC voltage, the millisecond (ms) level response time of the DC power supply cannot meet the application. The DC mode of the ASR AC source has a microsecond level ( us) response time makes up for the needs of this type of application. Time Mode rise time is less than or equal to 100us; Slope Mode (slope mode): rises at a fixed slope, rising 1.5V every 1us. Encyclopedia of AC power supply applications: Reasons why autotransformer cannot replace AC power supply The voltage still changes with the mains power (the purpose of measurement is to measure the unknown with the known, and the unknown with the unknown measurement cannot control the variables) The autotransformer cannot adjust the frequency: If your product is to be sold around the world, the specifications of the AC power frequency and frequency change rate in various places cannot be verified. The output impedance of the autotransformer will cause the output waveform to be non-sinusoidal, causing the PFC circuit of the device under test to track a non-sinusoidal reference signal.
