Description
Launching Q4 2026
The Bantam Nexus Series is more than a battery backup: it is a complete power conditioner and uninterruptible power supply in one. Where a typical UPS simply switches to battery during an outage and passes along whatever power quality it receives, the Nexus integrates Bantam’s proven SA3600 conditioning stage, delivering filtered Line, Neutral, and Ground power along with true battery backup and a pure sine wave output. The result is clean, protected, continuous power for the equipment your work depends on.
Our professional-grade power conditioning with superior surge protection is built for business and home-office professionals whose livelihood and reputation depend on high-quality, high-performance systems that demand safe, clean, and reliable power. This is not a consumer-grade battery backup meant to “sort-of” keep your inexpensive electronics alive for a few minutes.
Why Choose the Nexus™ Series?
- Nexus is a complete power conditioner and uninterruptible power supply in one.
- Provides battery backup that keeps critical equipment running through outages, sags, and brownouts.
- Produces a pure sine wave output for clean, stable power that sensitive electronics and power supplies depend on.
- Integrates the Bantam SA3600 conditioning stage, delivering full filtration on every outlet.
- Full utility passthrough: a 14 AWG cordset and 15 amp breaker deliver the complete energy available from a standard 15 amp, 120 V outlet.
- Every outlet is SA3600 filtered for both surge and power-line emissions (PLE) protection, whether battery backed or bypass.
- Smart battery allocation: on the 360, 800, and 1200, battery backup is directed to the outlets that need ride-through power while all outlets stay fully filtered; the flagship 1500 delivers battery backup on every outlet.
- Does not dump harmful energy to ground the way consumer surge protectors do; Nexus maintains a stable ground reference that digital equipment depends on.
- Filters EMI and RFI interference such as noise, flicker, hum, crackle, and harmful frequencies traveling along business and home power wiring.
- Suppresses power-line emissions (PLE): unwanted high-frequency signals that ride along power wiring, blocking them bi-directionally so they neither leak off your equipment nor couple onto it from the line.
- Comprehensive protection: overload, short circuit, over-temperature, and battery protection built in.
- Fan-assisted cooling that engages automatically only when needed, keeping the unit quiet under normal load.
Bantam Nexus is professional grade for the equipment your work depends on; everything else is just a battery in a box.
