5A UPS delivers 24V supply with RS interface
The supply-duration depends on the load current of the consumer but the batteries can be easily replaced, if necessary at all.
A switch-mode power-supply is built in that provides the needed power, maintaining a wide input voltage range. That means for AC an input voltage range from 85 to 270Volt and for DC an input voltage range from 120 to 400Volt. During mains operation the AC/DC converter supplies not only the equipment with power, but also the accumulator so as to always charge the batteries properly. The output is short-circuit-proof and effectively protected against polarity failure. Using the RS-232/ RS-485 interface status messages concerning input-voltage, temperature and accumulators can be received. The LDR can be also controlled by a local ECU.
