The AT2031XE Low Voltage Power Box is a compact, efficient low-voltage power supply device for industrial control and commercial electrical fields. It uses XBUS communication, ensuring good compatibility with other XBUS-equipped devices for easy system construction and expansion. Its working voltage (AC 170V–260V / 50Hz) adapts to most grid fluctuations, guaranteeing stable power output for connected equipment.
Unlike the AT2031X, it features a 5Ah / DC 7.4V backup power — lightweight and energy-saving, suitable for low-power equipment scenarios. With 0.5A function bus protection, it safeguards small-power devices and sensitive circuits. The same compact size (300mm × 220mm × 81mm) and wall-mounted design enable easy installation without professional skills.
Offering indoor, waterproof, and explosion-proof types, it adapts to various environments, providing a cost-effective power solution for small-power electrical control systems.
