BENTLY 3500/15 114M5335-01 Power Supply Module

Overview

The 3500/15 power supply occupies two slots in a 3500 rack and is available in various input voltage options. The specific model 114M5335-01 is configured for universal AC input (85-264 VAC) or high-voltage DC input (88-300 VDC), making it suitable for global applications. It provides +5 VDC and ±15 VDC outputs with total power up to 40 watts, sufficient to power a fully loaded 14-slot rack.

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.

• 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 interference.

• Front Panel LEDs: Visual indication of input power OK and output voltage OK.

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

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

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.

• Operating Temperature: -30°C to +65°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 interfaces, 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 or compressor stations.

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 114M5335-01 includes built-in overcurrent and overvoltage protection. Routine maintenance involves verifying LED status and checking for any firmware updates through the 3500 system configuration software.

In summary, the BENTLY 3500/15 114M5335-01 power supply module delivers robust and reliable power for the entire monitoring system, contributing to the overall integrity and uptime of your machinery protection strategy.
