- Generator Over/Under Voltage Guard, not affected by heavily distorted waveform
- Total processing time less than 50mS
- Integral true RMS transducer
- Triple relay operation gives more flexibility
Up to two individual very fast analogue output signals (<50mS), (optional)- DIN96 Slave Indicator with status LEDs (optional)
Description
The digitally controlled KCV114x provides precision protection of single-phase generators, motors, pumps etc.
True RMS measurement not affected by heavily distorted waveforms provides precision (1.0%) protection. Less than 50mS process time. The independent moving iron voltmeter accuracy is class 1,5.
The standard models takes the auxiliary supply voltage from the monitored voltage (terminal 1 & 2).
It can also be delivered with optional separate AC or DC auxiliary voltage (terminal 26 & 27), but that must be specified when ordering.
User settable trip levels and delays (definite time delays). Colour of LEDs indicate alarm status. Alarm LEDs flash during count-down.
Start of monitoring function is delayed when power is switched on (default 2 secs delay). In this way false tripping during power up is avoided.
The DIN-rail mounted instrument reads the voltage level directly in Volt. The optional slave volt-meter and the triple-zone status LEDs at a glance gives the clear safety message:
- HIGH (Over Voltage)
- NORMAL
- LOW (Under Voltage)
OUTPUTS
Up to two individual very fast analogue output signals (optional) proportional to Volt range. If output is used for remote meter reading, we recommend 0-1mA for the slave indicator.
RELAY OUTPUTS
Relay operation depends on the selected model (see page 2). Other combinations are available on request.
Description
KCV114E - KCV114FA - KCV114FB
Over and under voltage protection with a third relay (R3) that operates if either the over voltage relay (R2) and/or under voltage relay (R1) operate.
A timer will reset if fault is removed during count-down. Fixed hysteresis prevents relay "chatter".
Full functionality control during power-up/power-down, with 500mS power-out reservoir.
KCV114G - KCV114GFA - KCV114GFB
Over and under voltage protection with a third relay (R3) that operates if either the over voltage relay (R2) and/or under voltage relay (R1) operate.
A timer will reset if fault is removed during count-down.
Full functionality control during power-up/power-down, with 500mS power-out reservoir.
KCV114B - KCV114BFA - KCV114BFB
Over and under voltage protection with a third relay (R3) that operates if either the over voltage relay (R2) and/or under voltage relay (R1) operate.
A timer will reset if fault is removed during count-down. Fixed hysteresis prevents relay "chatter".
Full functionality control during power-up/power-down, with 500mS power-out reservoir.
KCV114HB - KCV114HBFA - KCV114HBFB
Over and under voltage protection with a third relay (R3) that
operates if either the over voltage relay (R2) and/or under voltage
relay (R1) operate.
