high-performance instrument designed for precise and stable power delivery in electronic testing and R&amp;D environments. With dual output ranges of 0 &#8211; 8 V\/5 A or 0 &#8211; 20 V\/2.5 A, it provides up to 50 W of clean, regulated power. The E3642A offers excellent load and line regulation (&lt;0.01%), fast transient response, and minimal ripple noise, making it ideal for powering sensitive circuits. Engineers benefit from its front and rear output terminals, built-in GPIB and RS-232 interfaces, and remote sensing capability, which compensates for voltage drops across leads. The power supply supports SCPI commands for easy automation and is compatible with LabVIEW and VEE software platforms. Its intuitive front panel, rotary knob, and memory recall functions enable efficient bench operation, while over-voltage protection ensures safety in demanding applications. The E3642A is built for precision, reliability, and ease of use in both development and production settings.<\/p>\n<figure id=\"attachment_184637\" aria-describedby=\"caption-attachment-184637\" style=\"width: 1422px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/techmaster.com.vn\/wp-content\/uploads\/2025\/04\/download-1.png\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-184637\" src=\"https:\/\/techmaster.com.vn\/wp-content\/uploads\/2025\/04\/download-1.png\" alt=\"DC Power Supply - Keysight E3642A\" width=\"1422\" height=\"705\" \/><\/a><figcaption id=\"caption-attachment-184637\" class=\"wp-caption-text\">DC Power Supply &#8211; Keysight E3642A<\/figcaption><\/figure>\n<div class=\"tm-en-blocks\"><\/div>\n<div class=\"kx\">\n<div class=\"block\">\n<div class=\"eyebrow\">Applications<\/div>\n<h2 id=\"apps-e3642a\">What is the Keysight E3642A used for?<\/h2>\n<div class=\"cards c3\">\n<div class=\"card\">\n<div class=\"i\">\ud83d\udd0b<\/div>\n<h3>Stable test power supply<\/h3>\n<\/div>\n<div class=\"card\">\n<div class=\"i\">\u2699\ufe0f<\/div>\n<h3>Load simulation and testing<\/h3>\n<\/div>\n<div class=\"card\">\n<div class=\"i\">\ud83d\udcca<\/div>\n<h3>Power consumption and efficiency measurement<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"kx\">\n<div class=\"block faq\">\n<div class=\"eyebrow\">Frequently asked questions<\/div>\n<h2 id=\"faq-e3642a\">Keysight E3642A \u2014 frequently asked questions<\/h2>\n<details>\n<summary>Where can I buy a genuine Keysight E3642A in Vietnam?<\/summary>\n<div class=\"a\">Techmaster Electronics is an authorised Keysight Technologies distributor in Vietnam.
