Volt Sensitive Battery Isolator (Battery Guard).
12/24 volt 20 amp
Solid State Battery Guard.
Protected to IP65.
length 155mm x width 30mm x height 15mm.
ECE and CE approved.
Monitors the battery voltage and disconnect load when the battery voltage reaches a pre-determined level.
The voltage level at which this device operates to disconnect or re-connect the load to the battery can be set to one of 10 different programmes by the installer using a simple bridge and integral LED indicator.
The unit also has an alarm circuit to power an audio and/or visual indicator to warn of imminent disconnect, allowing the operator 50 seconds to rectify the situation before disconnecting.
A 10 second delay is built in prior to an alarm,to prevent spurious warnings.
The alarm circuit is limited to 500mA maximum. If a higher current is required, a relay with a diode must be used.
Quiescent current is below 10mA for all versions.
Appropriate terminals and insulating covers are provided with each unit.
