Description
Bently 3500/15-125840-02
Technical Specifications
- Component Type: Low Voltage AC Power Input Module (PIM)
- Compatible Input Voltage: 85 to 132 Vac rms
- Input Frequency: 47 to 63 Hz
- Maximum Input Current: 4.5 A rms
Functional Features
- Over-Voltage Protection: Contains an internal fuse that opens to protect the power supply in case of an out-of-range voltage spike.
- Single-Point Grounding: Features a dedicated grounding switch (OPEN/CLOSED) to prevent ground loops and ensure proper system grounding.
- Secure Termination: Provides robust screw terminals for secure field wiring connections.
Application Scenarios
Used in conjunction with the 3500/15 Low Voltage AC power supply module in facilities utilizing 110 Vac or 120 Vac power distribution systems.
Performance Parameters
- Operating Temperature: -30°C to +65°C
- Storage Temperature: -40°C to +85°C
- Humidity: 95% non-condensing
- Insulation Resistance: >10 MΩ at 500 Vdc
Material Composition
High-current rated copper terminals with tin plating, ceramic or high-temperature thermoplastic housing, and fast-acting ceramic fuses.
Structural Characteristics
A half-height module that mounts directly behind the corresponding 3500/15 power supply module. Features front-facing terminal blocks and a grounding switch.
Working Principle
Routes incoming AC power through a protective fuse to the main power supply module. The grounding switch allows the installer to define whether the system ground is established at this PIM or at an external security barrier.
Installation Requirements
Must be installed directly behind its corresponding power supply module. Grounding switch must be configured according to the system grounding architecture.
Usage Notes
If the PIM fuse blows, identify and correct the root cause (e.g., external over-voltage) before replacing the fuse. Never bypass the internal fuse. Ensure all terminal screws are torqued to specification.
