Bently Nevada 3300/14-02-20-01 DC Power Supply

The Bently Nevada 3300/14-02-20-01 is a DC power supply module engineered to provide reliable, regulated power for up to 12 monitoring modules and their associated transducers within the 3300 series monitoring systems. Designed for industrial environments, it ensures consistent performance and system integrity.

Key Features

• Regulated Power Output: Delivers stable DC power, user-programmable to either -24 VDC or -18 VDC, accommodating various system requirements.
• Input Voltage Options: Supports a primary voltage operation range of 90 to 140 VDC, suitable for diverse industrial applications.
• Protection Mechanisms: Equipped with over-voltage and under-voltage protection circuitry, the power supply automatically shuts down if input voltage deviates from the specified range, resuming normal operation upon stabilization. Additionally, it features fuse protection against reverse polarity connections and excessive input voltages.
• OK Relay: Includes a hermetically-sealed single-pole, double-throw (SPDT) relay located behind the power supply in the Power Input Module, providing reliable status indication.
• Environmental Resilience: Operates effectively within a temperature range of 0°C to +65°C (+32°F to +150°F) and can be stored between -40°C to +85°C (-40°F to +185°F). It withstands relative humidity up to 95%, non-condensing.
• Compact Design: Occupies a single rack position, specifically the left-most slot (position 1) adjacent to the System Monitor, optimizing space within the 3300 rack system.
