3300/12-01-20-00 Bently Nevada AC Power Supply 3300 Rack Module

Product Introduction

The Bently Nevada 3300/12-01-20-00 is a high-performance AC Power Supply designed for the 3300 series monitoring system. It provides reliable and regulated power to a maximum of 12 monitors and their transducers. This module eliminates the need for redundant power supplies within a single rack. We highly recommend that engineering personnel download the 3300/12 technical manual and user handbook to ensure correct installation.

FAQ

Question: Can I convert a 110V unit to 220V in the field?

Answer: Yes, the input voltage is field-changeable by adjusting the soldered jumper and fuse.

Question: Does this module require a secondary backup power supply?

Answer: No, the 3300/12 is designed to power the entire rack independently.

Question: What is the lifespan of the integrated OK Relay?

Answer: The relay is rated for a minimum of 10,000 cycles at the rated load.

Question: Is this module suitable for high-humidity environments?

Answer: Yes, it operates safely in up to 95% non-condensing relative humidity.

Selection & Buying Guide

• Voltage Check: Confirm your site voltage (115V or 220V) before final installation.
• Approval Needs: If your site requires ATEX, verify the rack housing specifications first.
• Spares Planning: Keep one 3300/12-01-20-00 as a critical spare to minimize downtime.
• Authenticity: Ensure you are purchasing original Bently Nevada hardware for optimal E-E-A-T compliance.
