High-Power, Wide-Band Performance

Designed for demanding laboratory and industrial environments, the VSA-D Series delivers up to 1000 kVA output with a DC–10 kHz bandwidth, ensuring accurate waveform reproduction for vibration systems, actuators, and dynamic testing setups.
Professionals working with large loads and wide-frequency excitation can rely on stable, distortion-controlled power delivery.

Advanced Digital Control Architecture

• SPWM-based D-class topology for efficient, low-loss power conversion

• Multi-loop feedback control ensures ultra-stable output under varying loads

• High-speed ARM processor enables fast response and intuitive system management
  These digital advancements help engineers achieve more precise control with reduced system noise and improved reliability.

Smart Operation & Flexible Integration

Modern test environments require fast setup and remote operation.
The VSA-D Series addresses these needs with:

• Touch-panel user interface for simplified local operation

• Software-side gain start/adjustment, improving workflow speed

• Modular design (power, control, supply, interlock modules) for easy configuration and maintenance
  This reduces downtime and allows seamless integration with controllers, vibration shakers, actuators, and automated test benches.

Engineered for Reliability in Harsh Test Conditions

From high-duty vibration labs to continuous industrial excitation systems, engineers often face challenges such as power instability, heating, and noise.
The VSA-D Series is built to solve these pain points with:

• Soft-start technology preventing inrush currents

• Low-noise digital switching ensuring clean, stable output

• Rugged construction for long-term, continuous performance
