BENTLY 3500/15 114M5330-01 Power Supply Module

Overview

The 3500/15 power supply occupies two slots in a 3500 rack and is available in various input voltage options to accommodate different plant power systems. The 114M5330-01 typically accepts a wide‑range AC input (85‑264 VAC) or a high‑voltage DC input (88‑300 VDC), automatically adapting to the supplied voltage. It provides +5 VDC and ±15 VDC outputs with sufficient total power (up to 40 watts) to support a fully loaded 14‑slot rack, including monitoring modules, communication interfaces, and relay modules.

Key Features

• Redundant Operation: Two power supplies can be installed in the same rack for 1+1 redundancy. If one fails, the other seamlessly maintains power without interruption.

• Wide Input Range: Accepts 85‑264 VAC (47‑63 Hz) or 88‑300 VDC, with automatic range selection.

• Isolated Outputs: Provides electrically isolated DC outputs to prevent ground loops and reduce noise interference.

• Front Panel LEDs: Visual indication of input power OK and output voltage OK for quick status checks.

• Hot‑Swappable: Modules can be replaced without powering down the rack, minimizing downtime during maintenance.

• Protection: Built‑in overcurrent, overvoltage, and overtemperature protection.

• Compliance: Meets UL, CSA, and CE standards for safety and electromagnetic compatibility.

Technical Specifications

• Input Voltage: 85‑264 VAC or 88‑300 VDC.

• Output Voltages: +5 VDC @ 8 A, ±15 VDC @ 1.5 A (total 40 W max).

• Ripple & Noise: < 50 mV peak‑to‑peak.

• Efficiency: > 75% typical at full load.

• Operating Temperature: -30°C to +65°C.

• Storage Temperature: -40°C to +85°C.

• Dimensions: Standard 3500 module form factor (two slots wide).

Applications and Benefits

The 3500/15 power supply is essential for any 3500 series rack. It ensures that monitoring modules, communication processors, and relay modules receive clean and stable power, which is critical for accurate measurements and reliable alarm actuation. Redundant configurations are commonly used in critical machinery protection applications where continuous operation is mandatory, such as in turbine control rooms, compressor stations, and power generation facilities. The hot‑swappable design allows for power supply replacement without disrupting machine monitoring.

Installation and Maintenance

The module plugs directly into the backplane of the 3500 rack and is secured by front‑panel screws. No external wiring is needed except for the input power connection to the rack's terminal block. The 114M5330-01 includes built‑in diagnostics that report output voltage status to the rack interface module. Routine maintenance involves verifying LED status and checking for any firmware updates through the 3500 system configuration software. The robust construction ensures long service life even in demanding environments.

In summary, the BENTLY 3500/15 114M5330-01 power supply module delivers reliable and efficient power for the entire monitoring system, contributing to the overall integrity and uptime of your machinery protection strategy.
