The Chromalox MAX VI Multi-Zone SCR Power Controller consists of (6) SCR’s mounted on a highly efficient, fan cooled heatsink. The MAX VI heatsink features an all-metal bonded-fin design. Bonded-fin heatsinks have up to three times the cooling area of a conventional aluminum extrusion and therefore can dissipate more heat. Additionally, bonded-fin heatsinks offer a much smaller footprint. The MAX VI offers the flexibilty for (6) Single Phase Zero-Cross or Phase Fired Controllers. Additionally, the Zero-Cross mode can be configured into (3) Three Phase 2-leg controllers, or (2) Three Phase 3-leg controllers. The MAX VI offers current ratings of 25, 50, and 75 amps at 40˚C and Voltage ratings up to 600 VAC.

The MAX VI unit is fan cooled and provides up to 450 Amps of control power with a footprint dimension of 14.75" L x 9" W x 6.5” D. The MAX VI easily bolts to a chasis plate and all load wiring can dress down one side of the heatsink and all control wiring can dress down the other side. Each SCR incorporates a LED status indicator and IP20 touch protection removable cover.

The benefits from Chromalox MAX VI SCR controller are quick and low cost installation, reduced panel space, increased heater life due to fast cycling, and easy replacements for mechanical and mercury contactors.
