HS code：8517623990

Product Details：

Product Dimensions：

The Bently Nevada Power Board, specifically the 3500/15 Power Supply (and its associated Power Input Modules or PIMs) or the 3300/12 Power Supply, accepts a wide range of input voltages from plant power sources and converts them into the precise, stable DC voltages required by the other monitoring modules within the system rack. It's the backbone for powering sensors, monitoring cards, and communication modules.

Functionality:

Converts AC or DC input power into regulated DC voltages for the Bently Nevada monitoring system.
Provides power to all modules installed in the system rack (e.g., monitor modules, communication modules, relay modules).
Supports redundant power configurations for enhanced reliability, where two power supplies can operate in parallel, with one acting as a primary and the other as a backup.
Includes internal filtering to minimize electrical noise from the input power, ensuring clean power for sensitive electronics.

Types:

Universal AC Power Supply: Accepts a wide range of AC input voltages (e.g., 85 to 264 Vac rms) to be compatible with global power standards.
High Voltage DC Power Supply: Designed for specific high voltage DC inputs (e.g., 88 to 140 Vdc).
Low Voltage DC Power Supply: Designed for lower voltage DC inputs (e.g., 20 to 30 Vdc).
Each power supply module often pairs with a specific Power Input Module (PIM) that handles the primary input connection and initial conditioning.

Key Features:

Hot-Swappable: In redundant configurations, modules can typically be removed or inserted without disrupting the operation of the rack.
LED Indicators: Provides visual indication of operating status (e.g., "OK" LED).
Half-Height Module Design: Fits into designated slots on the left side of the Bently Nevada monitoring rack.
Over-voltage/Under-voltage Protection: Designed to protect itself and the system from out-of-range input voltages.

Product Parameters

Parameters for Bently Nevada Power Boards vary slightly depending on the specific model (e.g., 3500/15 or 3300/12) and the input power option:

Input Voltage Range:

Universal AC: 85 to 264 Vac rms (110 to 220 Vac nominal).
High Voltage DC: 88 to 140 Vdc.
Low Voltage DC: 20 to 30 Vdc.

Input Frequency (for AC): 47 to 63 Hz.
Full Rack Current Draw: Maximum current consumed by a fully populated rack (e.g., for 3500/15 Universal AC, ~2.8 A rms maximum; for Low Voltage DC, ~11.0 A maximum).
Output Voltage: Regulated DC voltages supplied internally to the rack's backplane for other modules (e.g., transducer power outputs of -24 Vdc).
Physical Dimensions: Half-height module; typically around 120.7 mm (4.75 in) height x 50.8 mm (2.0 in) width x 251.5 mm (9.9 in) depth for the power supply module itself. PIMs are typically narrower.
Weight: Approximately 1.39 kg (3.06 lb) for the power supply module.
Operating Temperature: Generally -30°C to +65°C (-22°F to +150°F).
Storage Temperature: -40°C to +85°C (-40°F to +185°F).
Humidity: 95%, non-condensing.
Agency Approvals: CSA/NRTL/C (Class 1, Division 2), CE Mark, ATEX, etc., depending on the specific model and options.

Product Advantages

High Reliability and Stability: Crucial for machinery protection systems where continuous operation is paramount. Bently Nevada power supplies are engineered for consistent performance in harsh industrial environments.
Redundancy Capability: The ability to install two power supplies in a single rack (one primary, one backup) ensures uninterrupted operation even if one power supply fails, significantly increasing system availability.
Wide Input Voltage Compatibility: Universal AC and various DC options allow for global application and compatibility with diverse plant power sources.
Robust Design: Built with industrial-grade components and a sturdy physical design to withstand vibration, temperature fluctuations, and electrical noise common in industrial settings.
Simplified Maintenance: Hot-swappable design allows for replacement of a faulty power supply without taking the entire monitoring system offline, minimizing downtime.
System Integration: Seamlessly integrates as a foundational component within the Bently Nevada 3500 (or 3300) series monitoring platform.

Important Considerations

Redundancy Configuration: While a single power supply can power a full rack, installing two for redundancy is highly recommended for critical machinery protection applications to prevent single points of failure.
Power Input Module (PIM) Compatibility: For older systems, ensure that the power supply module and its corresponding Power Input Module (PIM) are compatible versions (legacy vs. new revisions). Mixing them might not work.
Fuse Replacement: Over-voltage conditions can cause the fuse on the Power Input Module (PIM) to open, requiring replacement. Ensure spare fuses are readily available.
Installation Slots: Power supplies must be installed in the designated half-height slots on the left side of the Bently Nevada rack.
Environmental Limits: Always adhere to the specified operating temperature and humidity limits to ensure long-term reliability.
Proper Wiring: Ensure correct wiring and grounding practices are followed during installation to prevent electrical noise and ensure safety.
