Power Factor Correction 14 relay outputs

BELUK BLR-CX14-RL is an advanced automatic power factor regulator designed to optimise and monitor the power factor in low-voltage compensation systems. It is suitable for industrial and commercial electrical panels requiring precise and reliable reactive power management.

Key Features:

• Number of Steps: 14 relay outputs for switching capacitor banks (model CX14)

• Supply & Measuring Voltage: 90–550 V AC, single phase, 45–65 Hz, 5 VA

• Current Measurement: 15 mA – 6 A (single phase), compatible with CT ratios from 1–9600 (x/1A or x/5A)

• Control Outputs: Up to 14 relay outputs (normally open, common root), max. 250 V AC / 5 A per relay

• Static Outputs: Up to 12 open-collector outputs, 8–48 V DC / 100 mA

• Temperature Monitoring: NTC sensor input for fan control or alarm

• Alarm Contact: Volt-free relay (life contact), 250 V AC / 5 A

• Fan Control: Any relay output can be configured for fan operation based on temperature

• Display & Settings: LCD; factory pre-set for 400 V grids, user menus for voltage, CT/VT ratio, and advanced parameters

• Automatic Step Recognition: Learns and monitors capacitor step sizes; alarms for failed steps, blown fuses, or faulty contactors

• Over/Undervoltage Monitoring: Built-in protection with user-adjustable settings

• Communication: Optional TTL interface for data logging or Modbus (in CX-PLUS models)

• Mounting: Panel mount, 144 × 144 × 58 mm, cut-out 138 × 138 mm

• Protection: Front: IP50 (IP54 with gasket), Rear: IP20

• Ambient Temperature: -20°C to +70°C (operation), -40°C to +85°C (storage)

• Weight: Approx. 0.6 kg

• Standards: IEC 61010-1, IEC 61326, VDE 0110, VDE 0411

Applications:
Automatic power factor correction in industrial and commercial low-voltage distribution boards, capacitor banks, and compensation panels.
