Advanced Built-in Protection Systems
Overcurrent, overvoltage, overtemperature, short circuit, and phase loss protection are standard. The unit also includes soft-start ramp-up to prevent plating bath shock, automatic reverse polarity for periodic reversal cleaning cycles, and a digital process timer with alarm outputs for unattended operation. All protection thresholds are field-adjustable via the front panel or remote interface.
Target Industrial Applications
