What this product is
What this product is
A modular, heavy-duty 19-inch rack-mount physical enclosure platform that integrates AC utility input terminals, multi-position Flatpack2 rectifier backplane buses, a Smartpack controller interface, and pre-wired DC distribution breakers with battery low-voltage disconnectors.
What problem it solves
Eliminates footprint waste, chaotic cable routing, and integration headaches caused by separate power boxes in macro-sites; provides unified digital supervisory control and automatic battery cut-off logic in a compact form factor.
Who and where it is for
Ideal for 4G/5G macro and micro base stations, central offices, optical broadband nodes (OLT/FTTx), electric substation automation panels, and rail transit trackside signaling systems.
Core advantages
- All-in-One Space Saving Design: Integrates AC input, rectifier slots, DC distribution breakers, and controller inside a standardized 19-inch subrack.
- High Efficiency Operation: Operates with Flatpack2 HE modules delivering >96% conversion efficiency, drastically cutting site thermal load and energy bills.
- Intelligent Battery Protection: Built-in programmable Low Voltage Battery Disconnect (LVBD) / Load Disconnect (LVLD) contactors to prevent deep-discharge cell damage.
- Robust Grid & Field Reliability: Features wide AC input tolerance, multi-stage lightning surge suppression, and an industrial operational window of -40°C to +65°C.
