The MiniMax Series is specifically designed
for the OEM market. The plug-in options, flexible
I/O power wiring, space saving footprint,
I2t fusing and universal approvals make it an
excellent candidate for your product.
The MiniMax 2 is a Solid State, highly versatile
power pak with optional plug-in
and Shorted SCR Detection Boards. Firing
modes can be switched between On/Off and
proportional Zero Cross or DOT Firing power
control at any time based on process needs.
Chromalox’ exclusive DOT (Demand Oriented
Transfer) firing switches the fewest number of
cycles to provide the most precise zero crossover
control. At 50% output the unit’s output
alternates between three electrical cycles on
and three cycles off. At 51% the output continues
with three cycles on / three cycles off
and gradually integrates three extra “on” cycle
for the additional one percent. With the exception
of phase angle firing, DOT firing is the
most precise method of SCR control. DOT firing
is preferred in many applications because
phase angle firing creates unwanted RFI. DOT
is excellent for applications where consistent
heater/process temperature control is critical.
The MaxPac Viewer Configuration Software allows users to program a variety of parameters and settings into their MaxPac I, II, III and MiniMax I, II, and III power controllers. Power management, alarm monitoring, firing mode, and cycle time adjustment are just a few of the settings available. The software also has a service platform for troubleshooting and maintenance on the spot.
