# Elgar Test Equipment Elgar used to be a manufacturer of electronic alternating current (AC) power supplies. Today, however, Elgar is a division of Ametek with three sister companies: California Instruments, Sorensen, and Xantrex. As a division of Ametek, Elgar still manufactures top quality test equipment such as high-power AC sources, direct current (DC) electronic loads, oscillators, interface equipment, and signal generators. The many items in Ametek’s Elgar product line include programmable power supplies and power. When engineers need equipment for aviation-avionics testing, arbitrary waveform generation, and compliance tests, they shop at ValueTronics for new, used, and refurbished Elgar products at very affordable prices. ## Products in this collection - [CW801P Elgar AC Source Used](https://valuetronics.com/products/cw801p-elgar-ac-source-used) - 0.0 USD - [40V MOD.
