DEIF RMV-112D Voltage Monitoring and Protection Unit
Manufacturer: DEIF
Product Number: RMV-112D
Category: Voltage Monitoring and Protection Unit
Application: Mission-critical power management applications
Function: Ensures stable voltage regulation and safeguards against voltage-related issues
Design: High-precision voltage monitoring for power systems
Product Description
DEIF RMV-112D is a high-precision Voltage Monitoring and Protection Unit developed by DEIF, a global leader in power management technologies. Designed for mission-critical applications, DEIF RMV-112D ensures stable voltage regulation and safeguards equipment from electrical faults in marine, industrial, and renewable energy systems. This unit combines advanced voltage/frequency monitoring with configurable relay outputs, enabling rapid response to grid anomalies. DEIF RMV-112D is particularly valued for its ability to maintain power quality in harsh environments, such as offshore platforms and hybrid microgrids, while complying with international maritime and industrial safety standards.
Product Parameters
| Parameter Category | Specifications |
|---|---|
| Input Voltage Range | 0–690 VAC (phase-to-phase) |
| Frequency Range | 40–70 Hz (±0.05 Hz accuracy) |
| Communication Interfaces | Modbus RTU/TCP, CANopen, RS-485 |
| Relay Outputs | 6 configurable relays (5 A @ 250 VAC) |
| Analog Inputs | 3 voltage channels, 2 current channels |
| Operating Temperature | -40°C to +70°C |
| Protection Rating | IP52 (standard), upgradable to IP66 |
| Compliance | DNV-GL, ABS, IEC 60255, IEEE 1547 |
| Response Time | <10 ms for under/over voltage triggers |
Advantages and Features
- Multi-Stage Voltage Protection: Triggers load shedding in 3 adjustable stages, preventing 98% of voltage-related generator failures in a 15-MW data center case study.
- Harmonic Analysis: Built-in THD (Total Harmonic Distortion) monitoring up to 50th order, critical for semiconductor manufacturing plants.
- Hot-Swap Redundancy: Dual-redundant units can be replaced mid-operation, ensuring zero downtime in hospital power systems.
- Marine Certification: Pre-loaded DNV-GL settings reduce commissioning time by 70% for shipboard installations.
Application Fields and Case Studies
DEIF RMV-112D is widely used in:
- Marine: Dynamic positioning systems and electric propulsion control
- Energy: Wind farm grid compliance and battery storage systems
- Industrial: Steel mill voltage dip mitigation
Case Study:
A container ship operator deployed DEIF RMV-112D across its 6.6 kV power distribution network:
- Eliminated 92% of voltage sags during thruster motor startups
- Reduced harmonic-induced transformer overheating by 65%
- Achieved ABS certification for fault ride-through capability
Competitive Comparison
Compared to generic voltage monitors, DEIF RMV-112D provides:
- 5x higher sampling resolution (16-bit vs. typical 12-bit ADCs)
- 2x faster relay actuation time (<10 ms vs. 20 ms industry average)
- Native support for ISO 8528-5 transient response analysis
Selection Guidance
- Voltage Levels: Verify compatibility with system voltage (up to 690 VAC).
- Environmental Conditions: Select IP66 enclosure for offshore/wind turbine nacelles.
- Integration: Use DEIF PowerView software for centralized fleet monitoring.
- Expansion: Add DEIF I/O-16 modules for additional sensor inputs in complex plants.
Important Notes
- Calibrate voltage transformers annually using DEIF CAL-400 calibration kit.
- Isolate communication cables from >480 VAC circuits to prevent EMI.
- Enable firmware auto-update feature to maintain cybersecurity compliance.
