KCFV53x - THREE PHASE - 3-WIRE FREQUENCY AND VOLTAGE GUARD
- Under and Over Voltage and Frequency Protection
- Adjustable Voltage and Frequency Deviation Set points
- The Pathfinder function eases fault finding
Up to two individual very fast analogue output signals (<50mS), (optional)- DIN96 Slave Indicator with Hz scale (optional)
Description
The digitally controlled KCFV53x is for use on three phase, three wire systems. KCFV53x provides precision monitoring of frequency and line voltage on any generator system. When trip delays are set to zero (0,1sec) operation corresponds with G59 requirements.
User settable trip levels and delays. LEDs flash during count-down. Colour of LEDs indicates alarm status.
PATHFINDER FUNCTION
The Pathfinder (only on latching models) indicates the phase (s) causing the trip by the flashing pattern of the relevant LED.
OUTPUTS
Up to two individual very fast analogue output signals (optional)
proportional to Hz range. The analogue output is isolated from both
voltage input and auxiliary power.
Relay Configurations
Less than 50mS fault detection. R1 (Under & Over Frequency) and R2 (Under & Over Voltage) activates when set level is exceeded and time delay has elapsed. R3 activates when R1 or R2 is activated and can be used as a common alarm.
