Product Brief: Bently Nevada 190501-01-00-04 (1900/5A AC Power Supply)
The 190501-01-00-04 is a Universal AC Power Supply Module for the Bently Nevada 1900/5A Series monitoring system. It converts AC line power to the regulated DC voltages required by the 1900/5A chassis and its installed monitoring cards (e.g., vibration, temperature, relay modules). This hot-swappable unit allows replacement without system shutdown, improving uptime for general-purpose machinery monitoring.
Key Features
Universal AC input (85–264 VAC, 47–63 Hz) – works worldwide without jumpers.
Hot-swappable – replaceable while the system remains powered.
Single or redundant operation – one supply for basic systems; two for high availability.
Diagnostic LEDs – visual status indicators for power OK, fault, and over-temperature.
Over-voltage, over-current, and over-temperature protection.
Designed for 1900/5A rack – occupies designated slot(s) in the chassis.

Application Scenarios (use cases)
| Application Area | Description |
|---|---|
| 1900/5A Monitoring Rack in a Power Plant | Provides main or redundant AC power for a chassis monitoring cooling tower fans, pumps, and small motors. |
| Industrial Fan & Blower Monitoring Panel | Supplies clean DC power to vibration and temperature cards for general-purpose fans in HVAC or process ventilation. |
| Small Compressor Protection System | Powers the 1900/5A rack on a small reciprocating or screw compressor in a manufacturing plant. |
| Standalone Asset Monitoring Skid | Used in prefabricated monitoring skids for pump or gearbox protection where 24 VDC is not available (AC mains only). |
| Retrofit of Obsolete Systems | Replaces older 1900 series or competitor power supplies when upgrading to a 1900/5A chassis. |
Notes
This module is not compatible with 3500 series racks (different form factor and voltage requirements).
For redundant AC operation, two identical 190501-01-00-04 units must be installed in the designated chassis slots.
If 24 VDC input is required, use the DC power supply version (different part number, e.g., 190501-02-00-xx).
Always confirm total chassis power budget is ≤ 50 W (sum of all installed cards’ power consumption).
