Digital multimeter power testing industry
At present, the test of the power supply switching power supply using programmed test, an industrial computer and test equipment, PC software, a combination of this method can not only improve test efficiency, reduce costs, but also to accelerate the test speed, improve test accuracy and precision. Therefore, the major power companies need a more cost-effective, universal measurement device to meet a variety of power supply testing. This article the RIGOL depth a number of power companies research, the introduction of the use of the RIGOL digital multimeter to improve power detection solutions, and application examples of the DM3052 digital multimeter in a well-known power companies.

A new type of tracking SCR DC voltage-stabilized power supply design
In the information age, BP has become a commonly used communication tools. Currently, my BP machine total transmitting equipment adopt import equipment, the output voltage is 13. 8V, current is 15~20A. Importing power with Silicon parts, and large fluctuation in China, this design has such a low cost regulated power supply. The design on the basis of feedback adjustment type series power supply equipped with thyristor phase control device, used to adjust the ends of the pipe pressure drop control thyristor conduction angle that is triggered, maintain adjusted pipe pressure drop constant, to design the track-high power DC power supply. The voltage limit adjustment tube power, achieving high power.

From the Canon projectors LCOS projection technology trends
Lift the photo, what do you think? A moving picture good pictures!
Bring photographic tool, you do what comes to mind? Professional digital SLR camera!
Bring high-quality digital SLR camera, you tell me what comes to mind? Yes, it's professional digital SLR camera Canon EOS series!
Canon, with its leading-edge optical technology has continued to pursue high-quality image of this idea. From the prestigious professional EOS SLR camera, into the practical first Hirohide (Powershot) series, and then to the fashion yikesasi (IXUS) series of small digital cameras, as well as acclaimed civilian imaging products such as digital cameras and projectors. Canon is the persistent idea through to the image of all of its products.
