DEIF MTR-3F-215 Multi-Function Power Controller

Three-Phase Power Management Controller for Marine & Industrial Applications

Technical Specifications

Main Features and Advantages

Comprehensive Power Management: The DEIF MTR-3F-215 delivers precise three-phase monitoring with Class 0.5 accuracy for voltage, current, frequency, power factor, and energy consumption. Its integrated protection functions prevent equipment damage by instantly disconnecting loads during under/over voltage (adjustable 70-130% range), frequency deviations (adjustable 80-110%), and reverse power conditions.

Intelligent Load Control: Six configurable relay outputs enable sophisticated load management strategies. The controller automatically sequences critical loads during generator start-up, prioritizes essential equipment during low-power scenarios, and implements load shedding based on user-defined thresholds. This prevents generator overload while maximizing operational efficiency.

Marine-Grade Reliability: Designed for harsh environments, the DEIF MTR-3F-215 meets stringent marine certifications including DNV-GL, ABS, and Lloyd’s Register. Corrosion-resistant terminals and conformal-coated PCBs withstand saltwater exposure, while -25°C to +70°C operational range ensures performance in extreme temperatures.

Advanced Metering Capabilities: Beyond basic monitoring, the controller calculates total harmonic distortion (THD), records min/max values, and tracks energy consumption (kWh/kVARh) across multiple tariffs. The graphic LCD displays comprehensive system status including vector diagrams, power flow direction, and event logs with timestamped alarms.

Seamless System Integration: With native Modbus RTU and CAN bus interfaces, the DEIF MTR-3F-215 integrates with PLCs, SCADA systems, and power management software. Two analog outputs provide real-time power parameters to chart recorders or external displays, while configurable I/O mapping enables custom control schemes.
