Rack-mount Power Distribution Unit Helos PROFESSIONAL Model 262836 Offline UPS 19-inch

Helos PROFESSIONAL Model 262836 is a rack-mount power distribution unit with an offline UPS topology designed for 19-inch racks. It combines centralized power distribution and basic battery-backed protection to support network, server and telecom equipment. The unit is intended to organize power delivery inside server cabinets and professional AV or IT installations, offering short-term runtime to keep essential equipment running during brief outages and to enable controlled shutdowns when needed.

Advantages

The rack-mount design fits standard 19-inch cabinets and helps consolidate power connections for multiple devices in a single, accessible location. Offline UPS topology provides automatic, immediate switchover to battery power during mains interruptions, protecting sensitive equipment from unexpected shutdowns. Built for professional environments, the unit supports tidy cable management and centralizes power control within racks.

Suitable for

• Small to medium server racks and network cabinets
• Telecom and networking equipment requiring short-term backup
• Professional AV racks and broadcast installations
• Edge computing or branch office IT closets

When it may not be suitable

The offline UPS topology is intended to provide basic, short-duration backup and surge protection; it is not designed for long runtime or for environments that require seamless double-conversion online UPS performance. For sites with frequent or prolonged power outages, or for equipment that requires ultra-clean continuous power, a higher-capacity online UPS or longer runtime battery system would be more appropriate.

Key specifications

• Form factor: 19-inch rack-mount unit suitable for standard server cabinets
• Topology: Offline (standby) UPS with automatic battery switchover
• Primary function: Power distribution combined with basic battery backup
• Intended use: Protection against short mains interruptions and controlled shutdowns
• Typical applications: IT racks, network and telecom equipment, professional AV installations

How to use

Install the unit in a standard 19-inch rack using appropriate mounting hardware. Connect the mains input to a properly rated AC supply and route the outputs to the devices to be protected. Ensure batteries are installed and charged following the manufacturer's instructions before relying on backup power. During normal operation the unit provides mains power; when an interruption occurs it automatically switches to battery supply to maintain connected equipment for a short period. Monitor the unit periodically for battery health and secure cable management to avoid overloads.

What to consider before purchase

• Required runtime: estimate the load of connected devices and how long backup is needed
• Power capacity and outlet types required by the equipment you plan to connect
• Rack space and mounting orientation available in your cabinet
• Environmental conditions such as ventilation and ambient temperature in the rack

Recommendations

Place the unit in a well-ventilated rack location, avoid stacking heat-generating devices directly above, and perform periodic battery checks. Use the Helos PROFESSIONAL rack-mount PDU with offline UPS topology to secure essential networking or AV equipment against short interruptions, and plan for an alternative UPS solution if longer runtime or continuous online protection is required.
