DC UPS

Uninterruptible Power Supply (UPS) provides backup power when the flow of electricity stops or drops to an inadequate voltage. Backup power can be provided for a specific amount of time, so that generators can be activated or network components can be properly shut down.

Phoenix Supply DC UPS reliably continues to supply applications with power even if the supply network fails. The battery management system with IQ Technology and the industry’s strongest battery charger ensures superior system availability. The DC UPS can be incorporated into established industrial networks with the integrated Ethernet interface for PROFINET, EtherNet/IP, EtherCAT and USB. Individual solutions can be created by combining UPS modules for 24 V DC and output currents from 5 A to 40 A with power supplies and energy storage systems.

PowerStream PST-SP Series of battery backup power supplies are designed with a universal input (85 to 260 VAC, 47 to 63 Hz or 120 to 340 VDC), 12 or 24 V power supply with a built-in DC battery backup charger and switch. They can charge any 12 or 24 V SLA, VRLA, gel cell or AGM lead acid battery and instantly switch over to battery power upon power failure with zero crossover time. They can be used with or without the battery as DIN rail mount power supplies and are specifically designed for infrequent battery use. The charger charges the battery slowly and may not be applicable for systems with frequent power outages. The 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.

PULS DC-UPS are integrated with electrochemical double layer capacitors, are maintenance free and guarantee an uninterrupted power supply for periods measure in seconds. The DC-UPS with external VRLA batteries have batteries that are individually charged and monitored.
