WattBox WB-UPS-OL-2000-8 Online Double Conversion UPS 2000VA 8 Outlets

High-Capacity Online Backup Power for Larger Equipment Racks

The WattBox WB-UPS-OL-2000-8 is a 2000VA online double conversion UPS designed for larger AV racks, network closets, security systems, structured wiring areas, control systems, and business-critical electronics that need continuous conditioned power.

It includes 8 built-in UPS-backed outlets. Four always-on critical-load outlets remain powered until the battery is depleted, while four programmable outlets can shut down non-critical equipment at a selected battery level to preserve additional runtime for the devices that matter most.

Best Use Cases

• Larger network closets: Helps protect routers, firewalls, gateways, switches, modems, controllers, and core network infrastructure.
• Security camera systems: A strong fit for NVRs, PoE switches, routers, storage devices, and surveillance support equipment.
• AV racks: Useful for processors, media servers, distribution gear, streamers, control systems, and suitable AV components.
• Smart home systems: Helps protect automation processors, hubs, bridges, controllers, and supporting network gear.
• Small business equipment: Good for offices, studios, retail locations, conference rooms, and critical equipment areas where unexpected shutdowns can interrupt operations.
• Longer-runtime projects: Supports compatible external battery packs when the internal battery runtime is not enough.

Who Should Buy This?

This UPS is a strong choice if you need to protect several rack devices directly and require more output capacity than the 1000VA or 1500VA models.

It makes sense when you need online double conversion, zero transfer time, pure sinewave output, 8 built-in outlets, critical-load prioritization, programmable load shedding, computer-based configuration, optional network management, and expandable runtime.

Who Should Not Buy This?

This is more UPS than most small modem, router, or desktop setups require. For a light equipment load, a smaller WattBox UPS may be easier to install and more cost-effective.

This is also not the right model if you specifically need native OvrC UPS monitoring or OvrC-based load shedding. This is the non-OvrC WB-UPS-OL model. It uses PC software, USB, RS-232, and optional SNMP for configuration and monitoring.

Do not assume that the 2000VA rating means the UPS supplies 2000W at every output voltage. At 120V, the published maximum output is 1850W. Leave additional headroom for runtime performance, future equipment, and startup behavior.

Do not connect heaters, appliances, laser printers, power tools, or other unsuitable high-draw equipment. High-current power amplifiers should also be evaluated carefully before connection.

Installation Considerations

Before ordering, calculate the total wattage of every device that will connect to the UPS. Use the published watt capacity for your selected output voltage and leave enough headroom for better runtime, future equipment, and changing loads.

For a typical 120V installation, plan around the published 1850W maximum rather than assuming the unit can continuously supply 2000W.

This is a 20A-class UPS. Confirm the available branch circuit, receptacle, power cord connection, and installation requirements before purchase. Consult a qualified electrician when a compatible circuit or receptacle must be added.

Decide which devices should use the four always-on critical-load outlets. The modem, router, firewall, main switch, NVR, storage, and control processor will usually be more important than secondary streamers, displays, and nonessential accessories.

Use the PC utility software to configure the four programmable outlets. Turning off non-critical equipment as the battery level falls can preserve more runtime for core network, security, and control devices.

Confirm that the rack provides 2U of space, at least 20.08 inches of chassis depth plus clearance for rear cables, proper ventilation, and enough structural support for the UPS and any extended battery packs.

The UPS ships with its internal battery disconnected for safety. The battery connection must be completed according to the official instructions before the UPS is placed into service.

Runtime Expectations

Runtime depends on the connected load. The official internal-battery runtime chart estimates approximately:

• 100% load: 2 minutes and 26 seconds
• 70% load: 5 minutes and 19 seconds
• 50% load: 9 minutes and 34 seconds
• 30% load: 19 minutes and 17 seconds
• 20% load: 31 minutes and 40 seconds
• 10% load: 68 minutes and 23 seconds

These figures are planning estimates rather than guaranteed runtime. Battery condition, temperature, connected equipment, output voltage, configuration, and battery age can affect actual results.

Why Online Double Conversion Matters

A standby or line-interactive UPS may require a brief transition when utility power fails. Many devices tolerate that transition, but sensitive network, security, AV, and automation equipment may still reboot, disconnect, or lock up.

An online double conversion UPS continuously powers the connected load through its inverter. This provides zero transfer time and helps isolate connected equipment from fluctuations in the incoming power supply.

Why Critical and Programmable Outlets Matter

Not every rack device has the same priority during an outage. A router, firewall, core switch, NVR, or automation processor may need to stay online longer than a streamer, display, secondary switch, or nonessential accessory.

The four always-on outlets protect critical loads until the battery is depleted. The four programmable outlets can shut down less important devices at a selected battery level, preserving more runtime for the critical equipment.

Why Extended Battery Support Matters

The internal batteries are primarily intended to cover short outages, prevent immediate shutdowns, and provide time for orderly shutdown or power restoration.

For installations that need longer runtime, the WB-UPS-OL-2000-8 supports up to five compatible WB-UPS-EBP-18AH48V extended battery packs. Smart Battery Detection recognizes connected packs and automatically adjusts the recharge rate.
