The Projecta VSR150 has been designed as programmable to suit any vehicle. Rated to 150 Amps, this voltage sensitive isolator will suit both 12 volt and 24 volt vehicles.
Factory default settings will allow the unit to engage when the main start battery reaches a voltage of 13.3Volts. The isolator will disconnect when the start battery reaches 12.8Volts, with a delay of 10 seconds.
Programmable voltages: (optional)
The unit is completely programmable to suit your vehicle's voltage requirements.
Once installed, the isolator will allow you to 'SET' both the Cut-In voltage and the Cut-Out Voltage.
|Display Value||Display Description||Range||Step/Increment||Default Setting|
|U1||Cut-In Voltage||10 - 32 V||0.1 V||13.3 V|
|t1||Cut-In Delay||0-99 sec||5 sec
|U2||Cut-out Voltage||10 - 32 V||0.1 V||12.8 V|
|t2||Cut-out Delay||0-99 sec||5 sec||10 sec|
|Uh||High Voltage protection||10 - 32 V||0.1 V||15.5 V|
Manual OVERRIDE function:
If the starter battery is flat and the aux battery is charged, the battery isolator ca be used to connect both batteries to allow for jump starting.
- Press and hold the PUSH on the unit for 3 seconds, the LED display will show the combined voltage and the VSR150 will be in override mode for 60 seconds
- Crank the engine. Once the engine has started the unit will automatically cancel the override function and return to the automatic charging function.

The programmability of this VSR means I can run the primary Battery down lower than other VSRs would let me, freeing up capacity and leaving enough to start the engine. These guys have the cheapest price in Australia as well
