Product Description:

DEIF RMV-112D Protective Voltage Relay

Type: 3-Phase Under- and Over-Voltage Relay (Uni-line Series)

Series: RMV Series

Part Number/Item No.: RMV-112D/700000936 200

Country of Origin: Denmark (DEIF A/S)

Condition: New/Original Box (Complete with official DEIF installation manual).

Fits For: Designed for generator, motor, and transformer protection against adverse system voltage conditions in marine and land-based power distribution systems. It is applied for 3-phase voltage monitoring, load shedding, warning, and tripping automation across generators and transformers.

Key Capabilities & Features:

• 3-Phase RMS Voltage Protection: Monitors 3-phase AC voltage continuously with built-in ANSI code 27 (Under-Voltage) and ANSI code 59 (Over-Voltage) protection.
• Adjustable Set Points & Delay: Features independent potentiometers on the front panel for setting U > (100-20%), U < (80-100%), time delay (0-10 s), and hysteresis (1-10%).
• Status LEDs & Latch Option: Equipped with front LEDs for Power, Fault condition (U > /U < warning), and active Relay trip status.
• Industrial Mounting: Supports standard 35 mm DIN rail or base surface mounting with terminal block connections.
