UPS uninterruptible power supply output DC 24V?
If you want to output a DC 24V uninterruptible power supply, you can use 24V battery + control components to achieve, the simplest control element is a contactable 24V DC relay.
?When the electricity is normal for the 380 / 220VAC, the DC main circuit has a DC voltage, DC-AC AC inverter, the output stable 220V or 380V AC voltage, while the mains after the rectifier battery charge. When any of the mains undervoltage or sudden power failure, by the battery through the isolation diode switch to the DC circuit to send power. There is no switching time from power supply to the battery. When the battery energy is about to run out, the uninterruptible power supply sound and light alarm, and the battery discharge point to stop the inverter work, long warning. The uninterruptible power supply also has an overload protection function that, when overloaded (150% load), jumps to the bypass state and automatically returns when the load is normal. When a severe overload (over 200% of the rated load) occurs, the uninterruptible power supply immediately stops the inverter output and jumps to the bypass state, and the front input air switch may trip. Eliminate the fault, just close the switch, restart the machine began to resume work.
UPS output is stable 220V or 380V AC voltage. Can not output 24V DC, need to be equipped with the corresponding AC to DC equipment.
????UPS (Uninterruptible Power System), that is, uninterruptible power supply, is the battery (mostly lead-acid maintenance-free battery) connected with the host, through the host inverter and other modules to convert DC power into the main system equipment The Mainly used for a single computer, computer network systems or other power electronic equipment such as solenoid valves, pressure transmitters, etc. to provide a stable, uninterrupted power supply. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter zero switching method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS equipment is usually too high voltage or voltage can provide protection.
