5Amp. USV for 24V and 12V supply
– All complete in one Unit –
The Accupacks LDR4012 and LDR4024 with charging regulators serve to buffer 12Volt- and 24Volt systems.
The Accupack LDR will be connected between the line voltage and the installation, in order to provide DC to the equipment. In the event of a mains power failure, the “on board” sealed batteries supplies the system, connected to the outlet. The supply-duration depends on the load current of the consumer. The batteries could be easely replaced, if necessary.
To provide the needed power and in order to maintain a wide input voltage range, a switch-mode power-supply is built-in. That means for AC – input voltage a range from 85 to 270Volts and for DC – input voltage a range from 150 to 400Volts. During the online operation the AC/DC converter supplies the accumulator with optimal charging-voltage as well as the output load, in a way that under normal operation-conditions the batteries are allways properly charged. These modern power supply is designed in acordance to the relevant international regulations and works with high efficiency.
The output-voltage follows hereby the batterie voltage level. In any kind of operation, normal or emergency, the full load can be drawn from LDR4012 as well as from the LDR4024. For a limited period, the peak-current could exceed the nominal current up to 50%. The output is short-circuit-proof and effectively protected against polarity failure.
The 2 build in Relays allowed a remote monitoring of the significant status of the LDR.
