ABB RVC12-1/5A Power Factor Controller Data Sheet

Main Specifications

• Model: RVC12-1/5A

• Type: Power Factor Controller

• Power supply: AC 230 V ±10%, 50/60 Hz

• Control current: 5 A

• Relay outputs: 12 controllable relays for capacitor switching

• Control accuracy: ±0.01 (power factor)

• Display: LED or LCD for current power factor, voltage, and current

• Operating temperature: -10°C to +50°C

• Protection rating: IP20

• Mounting: Panel or DIN rail mounting

Features and Advantages

1. High-precision power factor control — Accurately monitors and adjusts the power factor to reduce reactive power losses.

2. Multiple relay outputs — Supports multiple capacitor banks for flexible reactive power compensation.

3. Intelligent control functions — Features overcompensation protection, time-delay switching, and staged compensation for system stability.

4. Easy installation and operation — Compact design, suitable for panel or rail mounting; intuitive user interface.

5. Industrial-grade reliability — Wide temperature range and anti-interference design suitable for industrial environments.

Typical Application Areas

• Power systems: Low and medium voltage distribution network power factor management

• Industrial production: Reactive power compensation in metallurgy, chemical, textile, paper, and other industries

• Commercial and large buildings: HVAC systems and electrical equipment power factor optimization

• Energy management systems: Improve power efficiency, reduce electricity costs and equipment load

• Water treatment and infrastructure: Pump stations, motors, and fans reactive power compensation

Precautions

1. Verify that the controller’s voltage, current, and load match before installation.

2. Ensure relay outputs match the capacity of the capacitor banks to avoid overload.

3. Install in a dry, well-ventilated environment; avoid high humidity and dust.

4. Regularly check wiring and relay status to ensure long-term reliability.

5. In case of abnormal power factor or controller alarm, stop the system immediately and check.
