The MiniMax Series is specifically designed
for the OEM market. The current limit, soft
start option, flexible I/O power wiring, space
saving footprint, I2t fusing with UL and cUL
approvals make it an excellent candidate for
your product.
The Chromalox Model MiniMax 1P utilizes Phase
Angle firing to modulate power to an inductive
or resistive load. Phase Angle control has the
advantage of proportioning every cycle thereby
providing very fine resolution of power. Fast responding
loads in which the resistance changes
as a function of temperature are excellent candidates
for Phase Angle control. The MiniMax
Soft Start feature assures that the load power
is gradually increased from zero to the value set
by the command signal in the event of a power
interruption. In addition to the Soft Start feature,
optional Current Limit is used to protect the load,
fuses, SCR controller, and the total system from
large surge currents that could occur at startup.
Chromalox MiniMax offers separate and adjustable
Zero, Gain, Manual Bias, and Current Limit
potentiometers for ease of calibration. Screw
type plug-in connectors for input signals, remote
shutdown, and optional Remote Manual Bias are
standard for easy customer interface.
