Core Technology Advantages:

• Symmetrical Compensation & Reversed Polarity Circuit: Ensures exceptionally smooth, linear output voltage regulation across the entire 0-420V range, eliminating step changes or non-linearity common in simpler designs.

• Precision Servo Drive: Provides stable, adjustable regulating speed for responsive voltage control.

• Robust Industrial Design: ONAN cooling ensures reliable thermal management during extended operation at full load (60 minutes continuous @ 100% rating).

• Enhanced Safety: Integrated interlocks prevent unsafe operating conditions between the regulator, control interface, and downstream switching devices.

• Clear System Status: Magnetic oil level gauge and position indicator with contacts provide essential operational feedback.
