The FEAS Accupack LDR40MH24-RS uninterruptible power supply (UPS) has an onboard 24 VDC switchmode power supply, integral batteries and serial communications.
The UPS connects between the line voltage (85–270 VAC or 120–400 VDC) and the field equipment and is capable of supplying full load currents of up to 5 A at 24 VDC. To allow for intermittent high current demands upon the system, the full load current can be exceeded by up to 50% for limited periods of time. Additionally, the output is short-circuit and polarity protected to prevent damage caused by incorrect installation.
During mains operation, the AC/DC converter supplies the load with power while also providing the sealed batteries with an optimal charging voltage. In the event of a mains power failure, the easily replaceable sealed batteries supply the load until the mains power is restored.
Using the LDR’s RS-232 or RS-485 interface, status messages relating to input voltage, temperature and battery capacity can be communicated to the upstream control system.
