Machinery Protection System Power Supply 3300/14-01-22-02

Product Overview

The Bently Nevada 3300/14-01-22-02 acts as the primary energy source for the 3300 Series machinery protection rack. This DC-to-DC power supply converts a 24V DC nominal input into the regulated voltages required by vibration, position, and speed monitoring modules. We supply this unit as 100% Brand New and Original, ensuring your critical rotating assets—such as turbines and compressors—remain under constant, fail-safe supervision.

Part Number Breakdown: 3300/14-AA-BB-CC

Technical Specifications

The 3300/14-01-22-02 utilizes high-grade filtering to deliver noise-free power to sensitive monitoring electronics:

• Input Voltage: 24 V DC Nominal

• Output Type: Multi-rail Regulated DC

• Rack Slot: Occupies the left-most position in the 3300 rack

• Isolation: Galvanically isolated input/output

• Compliance: Fully meets API 670 requirements for machinery protection

• Operating Temperature: –20 °C to +65 °C (–4 °F to +150 °F)

• Storage Temperature: –40 °C to +85 °C (–40 °F to +185 °F)

Engineering Advantages

The 3300/14-01-22-02 provides technical solutions for high-stakes industrial monitoring:

• Signal Integrity Protection: The module features aggressive galvanic isolation. This prevents electrical noise from the main plant power grid from leaching into the vibration measurement circuits, ensuring your sensors report true mechanical data without electronic interference.

• Redundancy Capability: The 3300/14-01-22-02 supports redundant power configurations. By installing two units, you eliminate a single point of failure; if one supply loses power, the secondary unit takes the load instantly without interrupting the machinery protection logic.

• Transient Load Handling: Engineered to manage the sudden current spikes associated with alarm relay activations and sensor startups, the module maintains steady voltage rails even during simultaneous multi-channel events.

• API 670 Compliant Design: Bently Nevada manufactures this supply to meet stringent American Petroleum Institute (API) 670 standards, guaranteeing the necessary hardware reliability for the oil, gas, and power generation sectors.

FAQs

Q: Can I use the 3300/14-01-22-02 in a rack powered by 115V AC?

A: No. This specific configuration (-01) requires a 24V DC nominal input. If your facility uses 115V or 230V AC, you must select the appropriate AC-input version of the 3300/14 power supply or use an external AC-to-DC converter.

Q: How do I confirm the power supply is functioning correctly?

A: The front panel features a green "OK" LED. If the power supply internal diagnostics detect a failure or if the input voltage drops below the functional threshold, the LED turns off and the rack "OK" relay trips, alerting your DCS or SCADA system immediately.

Q: Does this module support hot-swapping?

A: While Bently Nevada modules are robust, you should follow standard safety procedures. In redundant power configurations, you can replace one faulty 3300/14 unit while the rack remains powered by the second unit, provided you handle the rack with care to avoid shorts.

Q: What is the benefit of the -22 Agency Approval option?

A: The -22 option ensures the module complies with multiple international safety standards (including CSA and CENELEC), making it suitable for use in various hazardous area classifications globally.
