Technical Parameters & Selection Guide

To facilitate system design and procurement, we provide detailed electrical, mechanical, and environmental specifications. Custom configurations available for specialized applications.

Selection Considerations: When specifying this module, evaluate available input power sources (AC/DC/both), required system redundancy level (single or N+1), total power budget for installed monitoring modules (sum of module consumption), ambient temperature range at installation location, and applicable certification requirements (API 670, ATEX, IECEx for hazardous areas). For assistance with system architecture or compatibility verification, provide rack configuration details and our engineers will recommend optimal power supply quantity and arrangement.

Frequently Asked Questions (FAQ)

Q: How does the Bently Nevada 3500/15 power supply integrate with existing 3500 rack systems?
A: The module uses standard 3500 rack slot mounting with keyed connectors ensuring correct installation. Simply slide into available slot, secure front-panel latches, and verify LED status—no external wiring required for intra-rack power distribution. Supports both new installations and retrofit upgrades in legacy systems.

Q: What is the maximum number of monitoring modules one 3500/15 can power?
A: Total capacity is 192W (±24VDC at 4A per rail). Typical monitor modules consume 3-8W each; a single power supply can support approximately 8-12 standard modules depending on specific types installed. For larger racks or redundancy requirements, install multiple power supplies in parallel with automatic load sharing.

Q: What energy efficiency and cost savings can be expected with this power supply?
A: With >80% efficiency at full load and low standby consumption, the 3500/15 minimizes wasted energy compared to linear supplies. In 24/7 operation, efficient conversion reduces heat generation (lowering cooling costs) and extends component life. Actual savings depend on electricity rates and system utilization; redundant configurations provide reliability benefits that far outweigh marginal energy costs.

Q: What are the environmental and installation requirements for this power supply module?
A: Operating temperature range is -30°C to +65°C with 5-95% RH non-condensing humidity tolerance. Install in standard 19-inch rack or Bently Nevada chassis with adequate ventilation (minimum 25mm clearance recommended). Conformal coating provides protection against dust and moisture; for hazardous area installations, verify appropriate ATEX/IECEx certification variant is specified.

Q: Does the 3500/15 support remote monitoring and data acquisition protocols?
A: The power supply itself provides DC power and status indication (LED diagnostics). Remote monitoring of system health is achieved through 3500 rack communication modules (3500/92, 3500/95) which support Modbus TCP/RTU, Ethernet/IP, OPC, and proprietary protocols—enabling integration with DCS, SCADA, and condition monitoring software platforms for centralized diagnostics and predictive maintenance.

Q: Can this power supply operate in redundant configurations for critical applications?
A: Yes, the 3500/15 is specifically designed for N+1 redundancy. Install two or more units in the same rack; they automatically share load and provide seamless failover if one unit fails or requires maintenance. Hot-swap capability allows replacement without system shutdown, ensuring continuous protection for critical machinery.

Q: What certifications does the Bently Nevada 3500/15 hold for use in regulated industries?
A: Standard units carry API 670 certification (mandatory for many oil & gas applications), CE marking (European compliance), and UL/cUL listings (North America). Hazardous area variants available with ATEX (Europe) and IECEx (international) certifications for Zone 2/Division 2 installations. Verify specific certification requirements with your project specifications.
