This power supply is a universal input (85 to 260 volts AC, 47 to 63 Hz, or 120 to 340VDC) 12 volt (or 24 volt) power supply with DC Battery Backup. It charges any 12 volt (or 24 volt) lead acid battery and switches over to battery power upon power failure with zero crossover time. The charger current is small, so it charges the battery slowly and may not be applicable to systems having frequent, regular power outages.

The battery voltage is not regulated, so the 12 volt system will vary from about 13.6 to 10 volts during battery operation. The 24 volt system will vary between 27.2 to 20 volts during battery operation.

These units can also be used as high voltage input DC/DC converters with battery backup. The input voltage can be DC instead of AC if the supply voltage is between 140 to 340 VDC.

Overcurrent protection The power supply will continue to supply power up to 140% of rated current and then will go into "hiccough" mode, turning on briefly to check if the current is too high, then turn off again. During the "off" phase of the hiccough battery power is present.
LED Indicator LED is on when DC output is present
