ZM R online single phase to single phase transformer-less UPS

The ZM R UPS series, available in power ratings from 1 to 3 kVA, is an Online Double Conversion uninterruptible power supply designed to protect sensitive IT equipment, computer networks, security systems, laboratory equipment and other critical loads. With a unity output power factor (kW = kVA), ZM R enables full utilization of the UPS rated capacity, making it an ideal solution for modern high-density loads. Its flexible Rack/Tower convertible design, combined with a rotatable LCD display, allows installation either as a tower unit or inside a standard rack enclosure. Internal batteries provide reliable backup time, while the Hot-Swap battery feature enables battery replacement without shutting down the UPS or interrupting power to connected equipment. Advanced digital control, wide input voltage range, intelligent battery charging and smart fan speed regulation improve system reliability and extend component lifetime. The LCD display provides real-time information including input and output status, load level, battery capacity and alarm notifications. Equipped with USB and RS232 communication ports together with an intelligent communication slot, ZM R offers comprehensive monitoring and remote management capabilities. ZM R is a reliable and cost-effective power protection solution for small data centers, network racks and professional applications.
