KCV4x Series
 
KCV4x - BATTERY VOLTAGE GUARD
  • DC Voltage Guards
  • Direct input up to 100VDC, up to 2000VDC with HV adapter
  • Two individually settable relays
  • Triple relay for more flexibility
  • Up to two individual very fast analogue output signals (<50mS), (optional)
  • DIN96 Slave Indicator with full current scale (optional)
The KCV4x is a digitally controlled guard for monitoring of battery system voltage.

An AC or DC auxiliary voltage is required for the unit. A green LED indicates POWER on. 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 precision DIN96 slave moving coil meter reads the monitored parameter, and has low-reflection glass to ease reading at a distance.

The units three C/O relay outputs are configured as Low, High trip and Trip Status (R3). The triple-zone status LEDs at a glance gives the clear safety message:
  • HIGH
  • NORMAL
  • LOW
Up to two individual very fast analogue output signals (optional) proportional to a range (see page 2 for available outputs). The analogue output is isolated from the CT and auxiliary power.

The trip levels and trip delays are user settable on unit rear to suit most applications (see relay operation on page 2).

Red relay trip lamps flash instantly (approx. 1 flash per second) when the trip level is passed, the relay trips after elapsed delay. The lamp changes state and the trip relay operates after the pre-set delay. If a trip condition ends during the delay interval, the timer will automatically reset.

As standard the unit is supplied for automatic reset. Manual reset (latching relays) is optional (All G-versions).

The unit meets EN 60255-27 Cat. III, Pollution degree 2 and the relevant environmental and EMC tests specified in EN 60255-26 to comply with the requirements of the major Classification Societies.
