Multi-Channel Rectifiers (REC)

Multi-Channel Rectifiers (REC)

CerAnode’s REC Multi-Channel Rectifier is a versatile DC power supply designed to run multiple cathodic protection (CP) circuits from a single unit. Each channel can be independently adjusted to supply DC current to separate anode beds or protected structures, making the REC ideal for complex pipeline networks, multi-tank farms, or distributed CP systems. The REC provides reliable, stable DC output, flexibility in configuration, and simplifies CP system power management.

Key Features & Benefits

Design & Output Flexibility:

• Multi-Channel Output: Supports multiple, independently controlled outputs—each channel can feed different anode beds or structures, enabling a single rectifier unit to manage several protection zones.
• Adjustable Voltage/Current per Channel: Each circuit’s DC output can be tuned to match the required current or potential for its specific anode bed or structure.
• Isolation Between Channels: Independent circuits reduce interference and allow different grounding / bed configurations without cross-coupling.

Electrical Performance & Efficiency:

• Consistent DC Output: Provides clean DC current suitable for impressed-current cathodic protection (ICCP), ensuring effective polarization.
• High Efficiency Rectification: Modern rectifier designs reduce energy loss and minimize voltage ripple, improving overall power efficiency.
• Surge & Transient Protection: Many units include built-in surge arrestors or filtering to protect sensitive downstream CP components from voltage spikes or transients.

Durability & Environment:

• Robust Enclosure & Construction: Designed to withstand the environmental demands of CP sites—suitable for installation at remote stations, tank farms, or field junction boxes.
• Scalable for Large Systems: Because multiple beds or structures can be powered from one rectifier, system footprint and infrastructure costs can be reduced compared to multiple single-channel rectifiers.
• Simplified Maintenance: Centralized control and fewer separate units reduce maintenance complexity and the need for multiple power supplies.

Integration & Control:

• Compatible with Remote Monitoring / SCADA: Can integrate with remote monitoring modules, data loggers, and CP control systems for centralized status, alarms, and record-keeping.
• Flexible Input Power Options: Compatible with single- or three-phase AC input; adaptable to different site power supplies.
• Configurable Output Modes: Allows for different control modes per channel—constant current, constant voltage or potential-control depending on application (if supported by unit).

Applications

• Multi-zone pipeline corrosion protection where different segments require independent current control.
• Tank farms with several storage tanks needing separate CP circuits.
• Refineries or chemical plants with multiple process lines, vessels, or buried systems under one CP control unit.
• Facilities with both soil-side and submerged anode beds requiring different output settings.
