With its robust design and agency approvals, it ensures continuous operation in demanding industrial environments.

Technical Specifications Analysis

The 3500/15-05-05-02 features a universal AC input voltage range of 85 to 264 Vac rms, with nominal 110 to 220 Vac. It operates at 47 to 63 Hz and draws a maximum of 2.8 A rms. The power supply module measures 120.7 mm x 50.8 mm x 251.5 mm and weighs 1.39 kg. It includes a front panel Supply OK LED for status indication. The agency approval option 02 provides ATEX / IECEx / CSA (Class 1, Zone 2) certification, making it suitable for hazardous locations. Environmental limits include an operating temperature range of -30 °C to +65 °C and storage temperature from -40 °C to +85 °C, with 95% non-condensing humidity tolerance.

Application Scenarios & Usage Methods

This power supply is ideal for use in Bently Nevada 3500 monitoring racks within oil and gas refineries, chemical plants, and power generation facilities. In a typical setup, install the power supply module into the left-side half-height slots of the rack. For redundancy, populate both slots with identical units. Connect the universal AC Power Input Module (PIM) directly behind the supply. The universal AC design simplifies global deployment, as it accepts 85 to 264 Vac rms without manual voltage selection. Use the Supply OK LED to verify proper operation during commissioning and routine checks.

Installation Guide & Packing List

Install the power supply module in the designated half-height slot on the left side of the rack. Ensure the rack is powered off before insertion. Secure the module with the provided screws and connect the PIM. No minimum rack load is required. The package includes one 3500/15-05-05-02 power supply module and one universal AC Power Input Module. Verify all components against the packing slip upon receipt.

Purchasing Advice

When selecting a power supply for your 3500 rack, choose the 3500/15-05-05-02 for universal AC applications requiring hazardous area certification. Its wide input voltage range and ATEX/IECEx/CSA approval make it a versatile choice. For redundant configurations, order two units. Petro Auto Tech offers genuine Bently Nevada modules with fast worldwide shipping. Confirm your rack slot availability and input power type before ordering.

Repair & Maintenance Tips

Periodically inspect the power supply module for dust accumulation and clean with a dry, low-pressure air stream. Check the Supply OK LED during operation; if it extinguishes, replace the module. Store spare units in a clean, dry environment within the specified storage temperature range (-40 °C to +85 °C). Avoid exposure to condensation or corrosive atmospheres. Always use identical modules for redundant setups to maintain load sharing.
