EDLC is a power conditioning device that is most effective when used with radio and TV transmitters, telephone systems, medical equipment, compressors, AC motors and machinery tools. Characterised by different voltage regulation techniques and power absorption capabilities, EDLC (up to three–phase 800kVA) has built-in transient voltage suppressor circuit to cope with transient over-voltages originate from atmospheric discharges, high-attenuation isolation transformer to deal with common-mode noises, and EMI filtering circuit to suppress any transverse and common-mode interferences.
The two regulation technologies and wide power range makes EDLC an ideal protective device to be installed at the distribution lines in a fail-safe power system.
