The KPV4x 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 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:
The standard version has no analogue output. The optional F-version has an isolated analogue output signal proportional to meter deflection (see page 4 for available outputs).
The trip levels and trip delays are user settable on unit rear to suit most applications (see relay operation on page 2 & 3).
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 61010-1 Cat. III, Pollution degree 2 and the relevant
environmental and EMC tests specified in EN 61326-2-4 to comply with the
requirements of the major Classification Societies.
