BENTLY 3500/15-05-00-00 3500 series core power module

BENTLY 3500/15-05-00-00 3500 series core power module

Functional features:

Wide-range power input: Supports wide-range AC input, such as 85-264VAC, and can also use high-voltage DC input 

of 88-140VDC, which can be converted to stable output voltages such as 24VDC required by the system.

Redundant design: Single-module or dual-module redundant configuration is available. When the dual modules are 

installed, the lower part serves as the main power supply and the upper part as the backup power supply, and it 

supports hot plugging, which can ensure the continuous operation of the system.

Protection function: Built-in overload and short-circuit protection circuits can prevent the equipment from being 

damaged due to overload or short circuit.

Status indication: The power status is displayed through LED lights, facilitating quick problem diagnosis.

The working principle is as follows:

Input voltage conversion: This module can receive a wide range of AC input voltages, typically between 85 and 

264VAC, with a frequency of 50/60Hz. The module internally converts the input AC power into the DC power required 

by the system through an efficient power conversion circuit, typically with an output of 24VDC, to supply power to 

other modules in the 3500 series and ensure the normal operation of the entire system.

Redundant power supply mechanism: When two power modules are installed in the rack, the one located in the lower 

slot serves as the main power supply, and the one in the upper slot acts as the backup power supply. When the main 

power supply is operating normally, it supplies power to the system and simultaneously monitors the status of the 

backup power supply. When the main power supply malfunctions, such as abnormal input voltage or internal circuit 

faults, the backup power supply will automatically switch to work, taking over from the main power supply to supply 

power to the system, thereby ensuring the uninterrupted operation of the 3500 series system and maintaining the 

monitoring and protection functions of key mechanical equipment.

Protection circuit operation: The module is equipped with built-in overload protection and short-circuit protection 

circuits. When the output current exceeds the set overload threshold, the overload protection circuit will be activated 

to prevent the module from being damaged due to overload by limiting the current or cutting off the output, etc. If a 

short circuit occurs at the output end, the short-circuit protection circuit will respond promptly and cut off the power 

output within an extremely short time to prevent the module and other connected devices from being damaged due 

to excessive short-circuit current, ensuring system safety.

The principle of status indication: Modules are usually equipped with status indicator lights (LED lights). These 

indicator lights show the working status of the power module through different on/off states or colors, such as 

whether the power input is normal, whether the output voltage is stable, and whether there are any faults, etc. For 

instance, a green LED light indicates that the power supply is working properly, while a red LED light may suggest a 

malfunction, facilitating the operator to quickly assess the module's operational status and promptly carry out 

maintenance and troubleshooting.

Physical properties:

Dimensions: It is designed as a half-height module, with dimensions approximately 120.7mm × 50.8mm × 251.5mm 

(4.75 inches ×2.0 inches ×9.9 inches).

Weight: Approximately 1.39 kilograms (3.06 pounds).

Installation method: It needs to be installed in the designated slot on the left side of the 3500 system rack and can be 

mixed with other half-height and full-height modules.

Working environment: The working temperature range is generally -40 ℃ to + 70℃, which can adapt to relatively 

harsh industrial environments. The humidity requirement is 95% without condensation.

Main application fields

Power industry: It can be used for power supply in the condition monitoring systems of key equipment such as steam 

turbines and generators, ensuring that parameters such as vibration and displacement during equipment operation 

can be accurately monitored, promptly identifying potential equipment faults, and guaranteeing the stability and 

reliability of power production.

The oil and gas industry: During the extraction, transportation and processing of oil and gas, it provides power for the 

monitoring systems of rotating mechanical equipment such as compressors and pumps, which helps to diagnose 

equipment failures in advance, reduce downtime, improve production efficiency and lower maintenance costs.

Chemical industry: It is applicable to the power supply of monitoring systems for various equipment such as reaction 

vessels, agitators, and fans in chemical production. The chemical production environment is complex and has high 

requirements for equipment stability. This module can ensure the stable operation of the monitoring system, promptly

 detect equipment abnormalities, and prevent safety accidents and production losses caused by equipment failures.

Metallurgical industry: It can provide stable power supply for the condition monitoring systems of large equipment 

such as blast furnace blowers and rolling mills in metallurgical production. Real-time monitoring of the operating 

of the equipment helps to achieve predictive maintenance of the equipment, improve the utilization rate of the 

equipment, and ensure the continuity of metallurgical production.

Papermaking and printing industry: Monitoring systems applied to paper machines, printing machines and other 

equipment help monitor parameters such as vibration and temperature during the operation of the equipment, ensure 

the operation accuracy of the equipment, improve product quality, and reduce production interruptions caused by 

equipment failures.

Water treatment and environmental protection industry: It can be used for power supply of the condition monitoring 

system of water treatment equipment such as water pumps and fans, ensuring the normal operation of water 

treatment  facilities and guaranteeing that water quality meets standards. In environmental protection equipment, it 

can also

provide stable power supply for related monitoring equipment, facilitating the smooth progress of environmental 

protection work.
