Converts incoming AC utility power into stabilized DC power. It simultaneously feeds the inverter and keeps the battery bank fully charged.

Perform visual inspections of the battery jars for swelling, leakage, or corrosion. Record individual cell voltages.

Connect the input supply to the rectifier input terminals.

The rectifier converts incoming AC utility power into stabilized DC power. This DC voltage simultaneously feeds the internal inverter and maintains the connected battery bank at an optimal float charge. The HiPulse D utilizes a thyristor-controlled design to minimize input total harmonic distortion (THDI) and maintain a high input power factor.

If you change parameters (e.g., output voltage from 400V to 380V), annotate the manual near the parameter table. Future engineers will thank you.

In the event of a fire or catastrophic failure, press the external EPO button. This immediately shuts down the inverter, rectifier, static switch, and trips the battery breaker, isolating the load. Converts incoming AC utility power into stabilized DC power
