ETC D20 Dual 20A 2.4K Dimmer Module

The Standard Dimmer Module is designed for use in both Sensor+ and Unison Dimming Series modular rack enclosures. Standard Dimmer Modules provide cost-effective digital forward phase angle dimming for standard loads such as incandescent, low voltage, quartz, neon, cold-cathode and 2 and 4-wire fluorescent ballasts. The patented, high-density, dual modules feature modular installation and removal, fully magnetic circuit breakers and standard or enhanced risetime toroidal filters.
