High‑Temperature Industrial UPS Systems (up to 50°C)
High ambient temperatures shouldn’t take your power down. Xtreme Power’s lithium LiFePO₄ UPS family is purpose‑built for demanding, non‑climate‑controlled industrial spaces and remote locations—factory floors, outdoor enclosures, IDF closets, kiosks, and unmanned remote sites in rural areas (like solar facilities) that require reliable network access. Choose compact 1U protection with J90 or scalable 3‑phase resilience with Li90—both capable of operating in a wide temperature range up to 50°C (122°F).

Why lithium LiFePO₄ for high‑heat industrial environments?
- High thermal stability vs. VRLA and other lithium chemistries
- Longer service life (often up to ~15 years depending on conditions) and faster recharge
- Lightweight modules for easier service
- Better performance at high ambient temperature—reliable operation in hot, non‑climate‑controlled spaces
- Industrial UPSs are essential when backing up critical equipment operating in harsh, wide‑temperature environments

Built for hot, constrained, real‑world spaces
- Non‑climate‑controlled IDF closets and protected enclosures where ambient temperatures rise
- Outdoor kiosks, parking/transportation terminals, and gaming/casino cabinets
- Factory control rooms and automation panels
- Remote locations and unmanned sites in rural areas (e.g., solar facilities) that require reliable network access
Why our UPS survive high heat (industrial thermal design)
- Separate internal air channel directs hot air straight across the heat sink and out of the chassis
- Sensitive components—PCBs, control electronics, and connectors—are kept out of the primary hot‑air path to reduce thermal stress
- Robust component selection and airflow path help maintain performance at high ambient temperature up to 50°C (122°F)
Battery life vs. high temperature (why LiFePO₄ matters)
- High temperature environments greatly affect battery service life
- Rule of thumb: battery life drops ~50% for every 10°C rise above 25°C
- Example: a 10‑year battery rated at 25°C may be ~5 years at 35°C
- LiFePO₄ chemistry and proper thermal design help mitigate heat‑related degradation compared to VRLA
Compliance & safety
- LiFePO₄ chemistry (safer, thermally stable)
- TAA‑compliant J90/J90i models for government & education
- UL/cUL, FCC listings; surge protection and load protection policy on J90

Frequently Asked Questions
1: How hot can these UPS systems run?
Both J90 and Li90 are designed for reliable operation in ambient temperatures up to 50°C (122°F). Always allow adequate ventilation and follow clearance guidelines.
2: Do I need to derate the UPS at higher temps?
Li90 is specified for high‑temp performance up to 50°C with no derating to 40°C. For J90, most installations do not require derating up to the 50°C limit—consult each model’s datasheet and installation manual for details on ventilation and continuous load.
3: How long do the lithium batteries last?
LiFePO₄ typically provides up to ~10 years of service life with thousands of cycles (application dependent). That’s ~2–3x the life of VRLA, reducing maintenance and replacement costs.
4: What runtime can I expect?
J90 offers ~7 minutes at full load (longer at partial loads). Li90 can deliver up to ~45 minutes at full load with maximum battery modules. We’ll size runtime precisely to your load.
5: Are these systems TAA‑compliant?
Yes—J90 and J90i are TAA‑compliant. Li90 is ideal for government/education when 3‑phase power and centralized protection are needed.
6: What about remote management and truck‑roll reduction?
J90’s optional Web/SNMP card enables individual outlet control—so you can reboot devices remotely*. Li90 offers full SNMP/Modbus options with an onboard touchscreen for local diagnostics*.
7: What warranties are included?
J90 includes an industry‑leading 6‑year warranty (electronics and batteries). Li90 includes startup plus 2‑Year On‑Site service in the US/Canada and a 5‑Year battery warranty.
*Note: 5-year or 6-year warranty is not applicable for installations where the ambient temperature exceeds 30°C.
