Product Brief Introduction The Bently Nevada 8920-PS-D is a DC-input power supply module that converts external DC input into regulated DC power for the monitoring system rack.
Tag:

Technical Specifications Input: 24V DC nominal, 18–32V DC operating range; output: 5V DC main logic, ±15V DC analog, 24V DC field; total output power: 100W nominal; overvoltage, overcurrent and overtemperature protection; operating temperature: -40°C to +65°C.

Functional Features Multiple regulated DC outputs; comprehensive protection circuitry; power status indication; hot-pluggable design; redundant parallel operation capability.

Application Scenarios Machinery monitoring system power supply, DC-powered control cabinets, remote monitoring installations, redundant power system configurations.

Performance Parameters Low output ripple; fast transient response; high conversion efficiency; reliable protection response.

Material Composition Metal shielding chassis, DC-DC conversion circuit board, electrolytic capacitors, ferrite magnetics, gold-plated backplane connector.

Structural Characteristics Rack plug-in power module, front panel status and fault LEDs, rear backplane power interface.

Working Principle Converts the wide-range input DC voltage into multiple tightly regulated DC output voltages through isolated DC-DC conversion topology, and distributes power to all modules via the system backplane.

Installation Requirements Install in designated rack power slot; connect external 24V DC supply with circuit protection; verify output voltages before applying system load.

Usage Notes Do not exceed total system power rating; ensure adequate ventilation; replace at recommended service interval.
