    The RA121 consists of a processor and 12 dimmer channels of 1.2KW each. 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.
