The MaxPac Series is specifically designed for
the OEM market. The current limit, soft start
option, flexible I/O power wiring, space saving
footprint, optional lug kits, I2t fusing, UL and
cUL approvals make it an excellent candidate
for your product.
The Chromalox Model MaxPac IP 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 MaxPac 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, 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 MaxPac 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.
