Description
The Lumel NF20 Power Factor Controller for reactive power compensation. It controls external reactive power element (capacitor) to meet reactive power demand of the load. This reduces burden on source to supply additional reactive current. Precise and fast measurements are useful tool for system analysis. Powerful protection function protects system and switching element in case of system faults.
FEATURES OF THE NF20 POWER FACTOR CONTROLLER
► Programmable switch in time, switch off time and discharge time
► Alarm message and relay
► Monitoring of the individual banks kvar value
► Operation time of capacitor
► LCD display with 2 x 16 characters for ease of readability
► Relay steps: 4, 6 or 8 switching output available
► Measurement around 73 (Modbus) electrical parameters (40 displayed on display)
► True RMS measurement up to 31st harmonics
► Wide voltage measuring input: 30 to 550V AC (L-L / L-N) with accuracy of 0.5%
► Four-quadrant operation
► Interface RS485 Modbus for monitoring the PFC parameters remotely (optional)
► Wide auxiliary supply: 110 to 550 C ac/dc
► Capacitor switching count helps in increasing life of capacitor banks
