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.
