General Information
The Austdac intrinsically safe uninterruptible power supply type 12/LA/24 has been designed to provide I.S. uninterruptible power that operates a nominal 12 volt 880mA or 18 volt 284mA.

The input power for the UPS requires a nominal 110V or 240V Exd protected mains power, in order to charge the battery and provide an I.S. 12 volt or 18 volt output.

The UPS utilises a 12V 24AH sealed-lead-acid battery to overcome the troublesome memory effect exhibited by nickel cadmium batteries.

The unit has a built in charger that will charge the battery and support a load while the mains power exists. When the mains power is unavailable the UPS 12/LA/24 uses its battery to support the load and maintains a constant 12 volt or 18 volt I.S. supply. The output circuit of the UPS has the same parameters as the AC25W resistive power supply.

The UPS 12/LA/24 is also fitted with a timer that will disconnect power to the load, after a redefined time period of standby. A front panel mounted button can be used to reset the timer and provide load power for another time period. The timer can be disabled if not required.
