Please contact us so we can help you custom configure this product.
|
The RA121 rack mount dimmer is suitable for church, stage, theater, school, night club, live performances and other event and artistic applications. Each dimmer channel is protected by a 10 Amp circuit breaker. Heavy duty filtering chokes are used to reduce noise. Dimmer channel semiconductors exceed a 200% load carrying capacity overhead allowance. The RA121 may be controlled by DMX controllers and several types of wall remote stations. |

Architect & Engineer’s Specifications
The dimming system shall have 12 circuits with a load capacity of 1200 Watts per circuit. Each circuit is protected by a 10 Amp fast acting magnetic circuit breaker. An allowance of 200% overhead capacity is employed in the circuit design. The dimming system shall have rise time of not less then 450 microseconds. Programming setup and memory attributes is via a front panel LCD display with keypad controls. A user may program the system setup, dimmer attributes of Dim or Relay, softpatch, scene memories, and unit addresses via the front panel display and keypad controls. The dimming system will have a minimum of 100 programmable scenes. Scenes are recalled via standard 8 contact closures, and up to 32 remote stations using a RS-485 protocol. The dimming system shall use USITT standard DMX-512 protocol for direct control of the dimming circuits. Power requirements of the dimming system shall be 120/208VAC Three Phase or 120/240VAC Single Phase mode. Power connections shall be via terminal block. Control connections shall be via dual DB25 connectors. Mounting of the dimming system shall be on standard 19” EIA rack mount. Dimensions are 3.5” high, 19” wide, 13” deep. The weight shall be 27 lbs. The dimming system shall be a Lightronics RA121.
