Digital power controller Zerion Pulse™

closed-loop

Galex Ltd dedicated five years to R&D, conquering three major technical barriers of Gallium Nitride (GaN) power devices in industrial control, culminating in the launch of the Zerion Pulse™. This industrial controller series employs third-generation GaN power devices and Pulse Amplitude Modulation (PAM) architecture, delivering high-density, high-response control solutions for 8kW power-range equipment. Core Technical Challenges GaN Drive Reliability High-Frequency EMI Suppression Thermal Density Management Key Technical Advantages Space Efficiency Revolution 13.3 W/cm³ power density enables compact designs for space-constrained applications. Precision Control Capability 60 kHz carrier frequency achieves ±0.25% speed fluctuation control, ensuring stable operation of sensitive loads. Industrial Environment Robustness 540 VDC wide voltage input complies with EN 61000-4-11, withstanding 40% voltage sags within 10 ms. Multi-Fault Protection Quadruple protection circuits adopt hardware-direct-drive architecture; ≤1.5 μs overcurrent shutdown prevents power device avalanche failure.
