The Bently 106M1081-01 is a dedicated model of the Universal AC Power Input Module for the 3500 Series Machinery Protection System. As a core input component of the 3500/15 Series AC-DC power supply system, it must be used in conjunction with the corresponding universal AC power supply module (e.g., the universal AC power supply module model 106M1079-01) and is specifically designed for universal AC voltage input scenarios. Featuring a half-height structure, this module is precisely fitted to the designated mounting position on the left side of the 3500 rack. It boasts a wide voltage input range, reliable protection mechanisms and multi-scenario compliance certifications. It can stably transmit external AC power to the power supply module for conversion, providing safe and continuous power support for other functional modules in the entire 3500 rack. Meanwhile, it supports redundant configuration to ensure operational continuity of the system, making it widely applicable to critical scenarios such as industrial equipment condition monitoring.

Functions and Compatibility Features
Technical Specifications
Input Specifications
Compatible Input Voltage: Nominal voltage of 110–220 Vac, with an actual wide input range of 85–264 Vac (rms). The peak voltage can reach 120–373 Vac, making it compatible with AC power supply standards in most regions worldwide.
Input Frequency: 47–63 Hz, compatible with common industrial power frequencies and offering excellent frequency adaptability.
Physical Characteristics
Dimensions (H × W × D): 120.7 mm × 25.4 mm × 114.3 mm (metric system), corresponding to 4.75 in × 1.0 in × 4.5 in (imperial system). Designed as a half-height module, it meets the standardized installation space requirements of the 3500 rack.
Weight: 0.34 kg (metric system), approximately 0.75 lb (imperial system). Its lightweight design facilitates easy installation and maintenance.
Mounting Position: Must be installed in the dedicated half-height slot directly behind the corresponding universal AC power supply module in the 3500 rack, forming a compact installation layout with the power supply module.
Protection Mechanisms
Overvoltage Protection: When the input voltage exceeds the safe range, the built-in fuse of the module will automatically blow, preventing overvoltage current from damaging the power supply module and other connected 3500 modules, thus providing critical safety protection.
Undervoltage Protection: The module features undervoltage tolerance. If the input voltage falls below the standard range, it will not cause damage to the module itself or the supporting power supply module—only the power supply output efficiency will be affected, ensuring the hardware safety of the equipment.
Environmental Adaptability
Operating Temperature: -30 °C to +65 °C (equivalent to -22 °F to +150 °F), capable of adapting to extreme high and low temperature conditions in industrial sites.
Storage Temperature: -40 °C to +85 °C (equivalent to -40 °F to +185 °F), meeting the temperature requirements during equipment transportation and storage.
Humidity Tolerance: 95% relative humidity (non-condensing), suitable for high-humidity industrial environments and not prone to malfunction caused by humidity.
