The S4K4U6000C and the S4K6U10000C Industrial UPS Series are the first true online industrial uninterruptible power systems that provide flexible output voltage, an integrated maintenance bypass switch and internal batteries all in a slim 4U (7.0") or 6U (10.5") enclosure.
The S4K4U-C and S4K6U-C feature double conversion topology to provide the ultimate in protection against a wide range of potential power problems. Both series also feature wide input voltage windows to support critical loads without having to transfer to the batteryextending system availability when battery backup is truly needed.
The S4K4U-C design incorporates two 3 kVA, 120 V inverters, allowing flexible output voltage to meet mixed load voltage requirements. Output voltage is automatically configured to match the input configuration without requiring tap selections. Self-diagnostics simplify maintenance and troubleshooting, and the UPS is user serviceable. The standard maintenance bypass switch provides an additional level of protection.
