Bently Nevada 3500/15-A01-B01-C01 power module

Bently Nevada 3500/15-A01-B01-C01 Rack Power Module

1、 Model segmentation definition (3500/15-A01-B01-C01)
Model format: 3500/15-AXX-BXX-CXX Bentley
3500/15: Bentley 3500 system dedicated rack power module, half height size, can only be installed in the two power slots on the left side of the rack
A01 (upper slot power supply specification)
A=Upper slot power supply; 01=Low voltage AC input 85-132Vac, 47-63Hz
B01 (Lower Slot Power Supply Specification)
B=Lower slot power supply; 01=Low voltage AC input 85-132Vac
→ A01+B01=Dual 110VAC redundant AC power supply configuration
C01 (authentication option)
C=Security certification; 01=CSA/NRTL/C North American General Industrial Safety Certification, used in ordinary factories without explosion-proof areas
2、 Core functional positioning
The whole machine provides multiple isolated and regulated DC power supplies for all monitoring cards (3500/42M, 3500/50, 3500/92, etc.) of the 3500 rack, supports dual power redundant heat plugging, and meets the requirements of uninterrupted power supply for the protection system of steam turbine and compressor units.
A single module can independently carry the entire rack; Seamless switching between dual modules, one primary and one backup
Plug and unplug any power supply with power on, the rack will not stop and the monitoring signal will not be interrupted
3、 Electrical input and output parameters
1. Input (A01/B01: Low voltage AC 85-132Vac)
Voltage range: 85-132 VAC RMS
Frequency: 47-63 Hz
Maximum input current at full load: 4.5 A rms
Accessory: Must be equipped with a low-voltage AC PIM power input terminal module installed in the slot behind the power supply
2. Rack output (internal multi-channel voltage regulation)
The module converts multiple isolated DC channels internally to supply power to the backplane bus:
+5V digital logic power supply
± 15V analog signal conditioning power supply
The rated output power of the whole machine is about 30W, and it supports stable operation of a 14 slot fully equipped rack
Protection mechanism: overcurrent, short circuit, overheating, input undervoltage/overvoltage automatic lockout protection
3. Panel status indication
Front single green SUPERY OK LED: always on=power supply is normal; Off/flashing=input loss, overload, malfunction
4、 Mechanical and Environmental Specifications
Appearance: Half height module, dimensions 120.7mm (H) × 50.8mm (W) × 251.5mm (D)
Weight: 1.39 kg
Working temperature: -30 ℃~+65 ℃
Storage temperature: -40 ℃~+85 ℃
Humidity: 5% to 95% RH, no condensation
Protection: IP20, installed inside the control cabinet, not exposed to direct sunlight outdoors
5、 Redundant installation rules
Two half height power slots are reserved on the left side of the 3500 rack: upper=A channel, lower=B channel
3500/15-A01-B01-C01 is an integrated dual power module that occupies both upper and lower slots
Two independent 110VAC separate power sources (two different power supply circuits) to achieve redundant power supply and fault-tolerant capacity
Fault switching without delay, the unit vibration protection and overspeed interlock circuit are not affected by power supply fluctuations

6、 List of Supporting Components
Low voltage AC PIM input terminal board (matching wiring module behind the power supply)
110VAC shielded power cord
Rack Backplane Bus (Unified Allocation of Multiple DC Channels to All Monitoring Cards)
7、 Quick differentiation reference for suffixes in the same series
Model suffix power supply configuration applicable scenarios
3500/15-A01-B00-C01 single channel 110VAC, no power supply in the lower slot, small measuring point, no redundancy requirements
3500/15-A01-B01-C01 Dual 110VAC Redundant Power Plant/Petrochemical Key Unit Standard Configuration
3500/15-A05-B05-C02 Dual Universal Wide Width AC 85-264Vac+ATEX Explosion proof Chemical Explosion proof Area
3500/15-A04-B04-C01 dual channel 24VDC low-voltage DC self-contained power plant 220V DC system
8、 Key points for on-site use
Two 110VAC power supplies are recommended to be taken from two different UPS systems to avoid power outages in the same circuit and dual circuit failures
PIM terminal wiring should be shielded properly, and strong current cables and sensor signal wires should be routed separately
When there is a power failure, the upper computer 3500 software can read the power channel loss alarm and support interlocking output
Replacement of spare parts must strictly match the suffix A01/B01. Mixing high-voltage AC/DC models will burn out the rack backplane
