3500/15-07-07-00 Bently Nevada Low Voltage DC Module

Bently Nevada 3500/15-07-07-00 Low Voltage DC Power Supply for 3500 Racks

Key Technical Specifications of Model 3500/15-07-07-00

The Bently Nevada 3500/15-07-07-00 delivers reliable DC power to the entire 3500 monitoring system. Both the top and bottom slots use option 07, which is the low voltage DC supply. Input voltage accepts 20 to 30 Vdc nominal. Maximum input current reaches 11.0 A for low voltage DC operation.

Input frequency requirements are 47 to 63 Hz. The 3500/15-07-07-00 requires no minimum rack load. Therefore, you can operate it even with partially filled racks. This flexibility makes it ideal for system upgrades or phased installations.

A front panel Supply OK LED indicates normal operation. When this LED stays illuminated, the 3500/15-07-07-00 functions correctly. If the LED turns off, check your input connections immediately.

Mechanical Dimensions and Rack Space

This power supply module measures 120.7 mm x 50.8 mm x 251.5 mm (4.75 in x 2.0 in x 9.9 in). It weighs 1.39 kg (3.06 lb). The module occupies two half-height slots on the left side of the 3500 rack.

Both slots can hold a power supply at the same time. Consequently, you can configure redundant power supplies for maximum uptime. Each power supply requires a dedicated Power Input Module (PIM). The PIM mounts directly behind its associated power supply.

The PIM dimensions are 120.7 mm x 25.4 mm x 114.3 mm (4.75 in x 1.0 in x 4.5 in). It weighs only 0.34 kg (0.75 lb). This compact design saves valuable rack space.

Environmental Limits for Harsh Conditions

The Bently Nevada 3500/15-07-07-00 operates reliably in extreme environments. Operating temperature ranges from -30°C to +65°C (-22°F to +150°F). Storage temperature extends from -40°C to +85°C (-40°F to +185°F). Humidity tolerance reaches 95% non-condensing.

Furthermore, these specifications suit demanding industrial applications. For instance, you can deploy this power supply in turbine rooms, compressor stations, offshore platforms, or desert installations.

Installation Guidelines for the 3500/15-07-07-00

First, power down the 3500 rack completely. Next, slide the 3500/15-07-07-00 into the left-side half-height slots. Insert the top supply first if installing only one unit. Push firmly until the rear connectors engage fully.

For redundant operation, install a second identical supply in the remaining slot. Both supplies share the load automatically. If one unit fails, the other continues without any interruption. This redundancy is critical for continuous monitoring applications.

Finally, secure the module with the retaining screws. Connect low voltage DC power to the corresponding Power Input Module at the rear. Verify the Supply OK LED turns green before powering up the rest of the system.

Compatibility Notes for Users

The 3500/15-07-07-00 works only with low voltage DC Power Input Modules. It is not compatible with legacy high voltage DC or universal AC units. Therefore, always match this power supply with its correct PIM.

Agency approval option 00 means no certification. If your facility requires CSA, NRTL, ATEX, or IECEx approval, choose option 01 or 02 instead.

Why Choose Low Voltage DC Over Other Types

Low voltage DC offers advantages in certain applications. First, it provides higher current capacity at 11.0 A maximum. This suits racks with many monitoring modules. Second, low voltage DC is safer for maintenance personnel. Third, it integrates easily with existing 24 Vdc plant power systems.

Meanwhile, the 3500/15-07-07-00 maintains the same form factor as other 3500/15 supplies. Therefore, you can mix different supply types across different racks without mechanical issues.

Frequently Asked Questions (FAQ)

1. What is the maximum output current of the 3500/15-07-07-00?
The Bently Nevada 3500/15-07-07-00 delivers up to 11.0 A at low voltage DC. This is the highest among all 3500/15 options.

2. Can I use a single supply in the rack?
Yes. The 3500/15-07-07-00 works perfectly as a standalone supply. No minimum rack load is required.

3. How do I set up redundant power with this model?
Install two identical 3500/15-07-07-00 units in both half-height slots. They automatically share the load and provide seamless backup.

4. Is this power supply compatible with legacy 3500 racks?
Yes, but only with the matching low voltage DC Power Input Module. Do not mix with universal AC or legacy high voltage DC units.

5. What does the Supply OK LED indicate?
The LED lights up green when the 3500/15-07-07-00 operates normally. If the LED is off or dim, check your input voltage and connections immediately.
