Description
Applications
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. Bondedfin 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.
• Electric Ovens
• Plastics Machinery
• Packaging Equipment
• Food and Beverage Processing
Equipment
• Platen Heaters
• Transformer coupled loads
• Resistance Heating
• Contactor Replacement
• Mercury Relay Replacement
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.
