High-density 5000 VA online UPS

The CyberPower OL5KRTHDL is a double-conversion UPS rated at 5000 VA and 5000 W with unity power factor. It accepts 120 V to 280 VAC input and provides user-configurable output at 200, 208, 220, 230 or 240 VAC. The unit fits in a 3U rack or tower form factor and includes a pre-installed network management card for remote monitoring of up to 50 clients. Buyers needing longer runtime at full load or additional outlet count should consider other models.

ECO mode efficiency and sine-wave output

GreenPower UPS ECO Mode delivers up to 96 percent efficiency to reduce power consumption and thermal dissipation. The sine-wave output ensures clean power for sensitive equipment across the full 0 to 100 percent load range. Audible alarms signal battery mode, low battery, overload and UPS fault conditions. A serial interface port provides basic local connectivity alongside the network card. The unit is not suited for environments requiring silent fanless operation.

Hardwire terminal with locking outlets

A NEMA L6-30P power cord is included and a hardwire terminal option is available for permanent installation. Four locking outlets comprise two NEMA L6-20R and two NEMA L6-30R receptacles. Sealed lead-acid batteries recharge from zero to 90 percent in four hours and use replaceable RB1290X12 modules. Surge energy rating is 2430 joules with input fuse and circuit breaker protection. Installers without access to 30 A locking circuits or hardwire feeds cannot use this unit directly.

Questions about this item

How do I wire the hardwire terminals on the OL5KRTHDL, and which step is often missed?

Connect the input L6-30P cord or hardwire the 200-240 VAC supply to the terminals, then attach loads to the two L6-20R and two L6-30R outlets; the step often missed is configuring the output voltage to 200, 208, 220, 230 or 240 VAC via the LCD before powering on.

Which battery pack replaces the internal cells, and when should I plan the swap?

The replaceable pack is the RB1290X12; expect roughly four hours to recharge from 0 to 90 percent, so schedule replacement when runtime at full load drops below the rated 4.9 minutes or at half load below 14.3 minutes.

What thermal or overload limit triggers first during sustained full-load operation?

At 5000 W the UPS will sound the overload alarm and cut output immediately if the load exceeds 100 percent; the 2430 joule surge rating and input fuse/breaker protect the input side, but the output cutoff is the first active limit under continuous full load.
