Abstract

The invention is applicable to the field of electrical equipment tests, and particularly relates to a thermal load with the power capable of being continuously adjusted and a method. According to the thermal load with the power capable of being continuously adjusted and the method, an intelligent control module outputs a PWM control signal with the changeable duty ratio to control connection and disconnection of one electric heating tube through a PWM control port to achieve continuous adjustment of the power from 0-W, controls connection and disconnection of the other (N-1) electric heating tubes through an on-off control port to achieve continuous adjustment of the power from W-(N-1)*W, and achieves continuous adjustment of the power from 0-N*W by controlling the N electric heating tubes comprehensively, and therefore continuous adjustment of the power of the thermal load is achieved.

Description

technical field [0001] The invention belongs to the field of electric equipment testing, and in particular relates to a thermal load capable of continuously adjusting power and a method thereof. Background technique [0002] AC power equipment and systems such as UPS, backup generator sets, and power supplies for large computer rooms need to undergo a large number of strict tests during the production and construction process to ensure product qualification, and regular inspections must be carried out during the trial process to ensure that they meet the requirements. Performance indicators, AC load is an essential device in the production testing process. During the period of rapid development of informatization in recent years, key industries such as banking, communications, medical care, and the Internet have deeply adopted information technology in their daily business, and extensively use UPS, backup generator sets and other equipment to ensure uninterrupted power suppl...
