350–600 VA | 120V | Ultra-Compact Lithium UPS
Ultra-compact lithium UPS engineered for embedded systems, control panels, and space-constrained electronic environments where traditional UPS platforms cannot be deployed.
Slim and lightweight, the J60 delivers long-term power protection for critical electronics in space-constrained environments. LiFePO₄ chemistry provides up to 15 years of service life in standby or float applications, or 3,000-5,000 partial discharge cycles, far exceeding traditional UPS solutions, and the J60 runs continuously at temperatures up to 50 °C (122 °F).
Its compact form factor makes it ideal for automation systems, video walls, PoE switches, programmable logic controllers (PLCs), kiosks, industrial computers, and point-of-sale equipment where a conventional UPS won’t fit. Learn more in the lithium UPS guide →

Thin enough to mount on walls, under counters, or directly inside equipment and enclosures. Mounting brackets are included standard; a DIN-rail kit is optional.
Lithium Iron Phosphate batteries provide protection for up to 15 years in float service, or 3,000-5,000 partial discharge cycles, far exceeding VRLA and cutting maintenance.
Runs continuously to 50 °C (122 °F), derated above 40 °C, suited to industrial enclosures and demanding thermal environments.
Operates at up to 98% efficiency in normal mode, lowering utility cost and reducing heat output in enclosed installations.
LFP chemistry avoids the scheduled battery replacement cycle required by VRLA, reducing service visits and lifetime cost of ownership.
An optional offset / right-angle 5-15P line cord clears the wall behind a display or inside a shallow enclosure, and an optional DIN-rail kit mounts the J60 in a control cabinet.
On the J60-600, an optional external Web/SNMP card adds monitoring and remote on/off control of output to reboot loads, plus optional temperature and humidity monitoring. Not available on the J60-600U.
Most UPS systems are designed for rack or floor deployment and can’t be installed inside equipment or shallow enclosures. The J60 integrates UPS functionality into an ultra-thin form factor, supporting localized continuity directly at the device or subsystem level, aligned with the distributed power architectures used in industrial systems, telecom infrastructure, and embedded electronics. Standby topology keeps operation efficient while providing reliable ride-through and controlled shutdown.
The J60 goes where a conventional UPS will not fit. At 1.25 inches thin it mounts on a wall, under a counter, on a DIN rail, or inside the equipment enclosure itself, which puts battery ride-through at the device instead of back at the rack. As a guide, 350 VA suits instrumentation and embedded electronics, while 600 VA suits communications and control systems. Runtime is sized for ride-through and controlled shutdown rather than extended operation. Size it with the UPS selector →
Menu boards, video walls, and wayfinding screens lose their content and need a manual restart after a brief outage. The J60 mounts flat behind the panel or inside the enclosure, and an optional offset plug keeps the cord from fouling a wall-mounted screen.
Self-service kiosks, ticketing machines, and POS terminals are often the only equipment in the room and rarely have a rack. An abrupt shutdown risks a corrupted transaction and a service call to a site with no technician on hand.
A small PoE switch in a ceiling space or closet takes cameras, phones, and access points down with it when it drops. The J60 holds a 30 to 50 W switch for well over an hour, long enough to ride out most utility events.
Programmable logic controllers and HMIs sit in cabinets that run hot and have no room for a tower UPS. LiFePO₄ operation to 50 °C and an optional DIN-rail kit let the J60 live in the panel with the equipment it protects.
Access control and surveillance are the systems least able to afford a gap. Distributed J60 units keep each controller and recorder alive independently, without extending a single central battery across the building.
For equipment builders, the J60 provides power continuity as a component rather than an accessory the end user has to source. Fifteen-year float life means the UPS is not the part that sets the service interval.
Where electrical noise is also a concern, the JX Series isolation transformer power conditioner → shares the same 1.25-inch flat-pack footprint. The JX delivers isolated, noise-filtered, surge-protected power; the J60 adds battery ride-through during an outage. Together they protect POS, kiosk, Starlink, and AV equipment from both electrical noise and power loss.
