UPS Backup Systems
Lawrence Berkeley Lab puts the cost of US power interruptions at roughly $44B annually. Our UL 1778 UPS uses true online double-conversion with IGBT PWM and DSP — zero transfer, nine power problems eliminated. Engineered to your exact load, voltage, runtime, and bypass requirements. Built to order in Los Angeles.

Zero transfer time eliminates the most dangerous milliseconds
Line-interactive UPS systems have a 4 to 10 millisecond transfer gap. Standby units gap for 5 to 12 milliseconds. For sensitive PLCs, process controllers, and medical instruments, those milliseconds cause shutdowns, data corruption, and production loss. Online double conversion means your load never sees the switch because there is no switch.
Engineered to your load, not the nearest catalog size
Off-the-shelf UPS vendors offer fixed kVA increments that force oversizing or undersizing. Online Power builds to your exact specification including voltage, frequency, runtime, bypass configuration, enclosure type, and monitoring integration. No compromises and no wasted capacity.
Internal static bypass plus external maintenance bypass
The internal static bypass activates automatically in under 4 milliseconds during a fault condition. The external wrap-around maintenance bypass uses make-before-break switching for zero-downtime UPS service, completely isolating the unit for repair without interrupting your critical load. Both should always be specified.
What your spec sheet won't tell you
UL 1778 and UL 924 certify fundamentally different things. UL 1778 certifies power continuity and quality for UPS equipment. UL 924 certifies emergency life-safety lighting compliance including 90 minute runtime, 10 second activation, and tamperproof design. A UPS with only UL 1778 listing does not satisfy NEC Article 700 emergency system requirements and your AHJ will reject it for emergency lighting applications. Online Power offers dual-listed UL 924 and UL 1778 models that satisfy both standards with a single unit. Also, demand actual efficiency curves at 25 percent, 50 percent, 75 percent, and 100 percent load from any vendor, not just the peak number. A UPS running at 30 percent load for most of its life at 85 percent efficiency costs far more in electricity than one maintaining 94 percent across all load points.
