KCVF594 - COMBINED VOLTAGE AND FREQUENCY GUARD
- High an Low Voltage Alarms
- High and Low Frequency Alarms
Description
The KCVF594 is a fully self contained "All in One" instrument which
measures and monitors both voltage and frequency in AC power systems.
The instrument has been designed to meet the G59 requirements for under
and over voltage and frequency protection.
Model KCVF594 is designed for three phase, four wire systems
Applications
Voltage and Frequency limits can be adjusted by potentiometers mounted
on the front of the instrument. Each model has three possible nominal
voltage settings – e.g. 380, 400 and 415V which are selected by
switches under the cover.
The appropriate RED "tripped" LED is
illuminated on a first up principle when the pre-set voltage or
frequency limit is exceeded. The trip relay is fail safe and will
de-energise instantaneously on operation (maximum 300 milliseconds).
Following a fault operation the relays latch and can be reset by an
external inhibit/reset switch.
Repeater open collector transistor
outputs are provided for remote indication or annunciation purposes.
