Selecting MUNK / MUNK GmbH Rectifier Architectures

Select between switch-mode PSP units, multi-circuit AxD pulse rectifiers, and water-cooled thyristor cabinets up to 100,000 A by current density, ripple limits, and ambient cooling conditions.

Modular air-cooled PSP Tower systems (36 kW / 2,000 A per block, up to 10,000 A) and water-cooled IP 54 PSP 5080/60100 cabinets maximize efficiency and save floor space.

For high-voltage electrolysis and hydrogen plants (0.5-5.0 MW), H2 Series water-cooled rectifiers deliver 200-900 V DC at up to 96% efficiency with SIL 2 safety, while DCAC 1200 and CDC/ADC Group 1-3 serve aluminum coloring and dip-coating lines.

Pulse Waveforms, Automation and Plant Integration

Periodic Pulse Reverse (PPR) processes rely on AxD Cabinet (1-8 circuits, IPulse 7,200 A) and AxD Compact (1-4 outputs, IPulse 1,800 A) controlled via VPC 3.0 software, or a wear-free 2,000 A SiC polarity reverser.

Standard fieldbus options include ProfiNet, Profibus DP, MODBUS RS-232/485, Ethernet IP, and isolated 0-10 VDC / 4-20 mA signals across MPS 1200 controllers and PKA 2 tank protection.
