It is designed to work with the High Voltage DC Power Input Module (PIM) to ensure your system operates without interruption.
Technical Specifications Breakdown
The 129486-01 operates with an input voltage range of 88 to 140 Vdc, making it suitable for various industrial environments. It draws a maximum full rack current of 2.5 A, ensuring efficient power distribution. The module features a Supply OK LED on the front panel, which illuminates when the power supply is functioning correctly. Physical dimensions are 120.7 mm x 50.8 mm x 251.5 mm (4.75 in x 2.0 in x 9.9 in), and it weighs 1.39 kg (3.06 lb). The module occupies two half-height slots on the left side of the rack, allowing for redundant power supply configurations.
Industry Applications
This power supply module is ideal for use in turbine monitoring systems, compressor control panels, and other rotating machinery protection applications. In a typical setup, the 129486-01 provides the necessary DC power to the monitoring rack, ensuring continuous data acquisition and alarm functionality. Its wide operating temperature range of -30 °C to +65 °C makes it suitable for harsh environments, such as those found in oil and gas facilities or power generation plants.
Installation & Setup Guidance
When installing the 129486-01, ensure the rack is powered off and properly grounded. Insert the module into one of the two half-height slots on the left side of the rack. Secure it with the provided mounting hardware. Connect the high voltage DC input (88-140 Vdc) to the corresponding terminals on the Power Input Module. Verify the Supply OK LED illuminates after power-up. For redundant configurations, install a second power supply in the adjacent slot.
Maintenance & Reliability
Regularly inspect the front panel LEDs to confirm the Supply OK indicator remains lit. Keep the module free from dust and debris to ensure proper airflow. The module is designed for long-term reliability, with no minimum rack load required. Store the unit within the specified storage temperature range of -40 °C to +85 °C when not in use. The humidity limit of 95% non-condensing ensures stable operation in damp conditions.
