Description
The Delta 20DRCG9.1 is a single-phase EMI (electromagnetic interference) power line filter, built by Delta Electronics to suppress conducted electrical noise on AC power lines. Housed in a rugged metal chassis-mount enclosure, it's designed to be installed at the power entry point of electronic equipment to reduce both common-mode and differential-mode noise, helping devices meet EMC compliance requirements while protecting against interference from the AC mains.
As printed on the label, this filter is rated for 100–250V, 50/60Hz, 20A operation, with the internal circuit built from an inductor (L: 4×2.0mH) and capacitor network (2×1.47µF + 0.33µF X2SH, plus 2×2200pF Y-caps) to deliver effective line filtering. The unit carries UL/hipot testing markings and is rated for use up to 250V, making it broadly compatible with standard AC line voltages worldwide.
Wiring is clearly labeled directly on the case — LINE (Black/Brown) and LOAD (Brown) terminals for the live connection, and White/Blue for neutral — along with quick-connect spade terminals for straightforward installation into power supply lines of industrial equipment, machinery, audio/video gear, and other AC-powered electronics where noise suppression is required.
