  • Core Advantages

    • High-Voltage DC Input Capability: The module accepts 88–140 VDC input voltage, making it ideal for DC-powered industrial environments, battery-backed systems, and remote installations where AC power is unavailable or unreliable.

    • Redundant Configuration Support: The 3500 rack can contain one or two power supplies in any combination of AC and DC. When two power supplies are installed, the lower slot acts as the primary supply and the upper slot acts as the backup. Removing or inserting either power supply module does not disrupt rack operation as long as a second supply is installed.

    • Hot-Swap Capability: With redundant configuration, the module supports hot-swap replacement, allowing maintenance or replacement without interrupting the operation of the rack and its monitoring modules.

    • Comprehensive Protection Features: The power supply includes overvoltage, overcurrent, and overtemperature protection. Internal surge suppression circuits resist transient voltage impact from substation environments, while an internal fuse opens in case of over-voltage conditions.

    • Self-Monitoring Diagnostic Function: The module features a front-panel Supply OK LED that indicates when the power supply is operating properly, enabling quick local inspection without software login.

    • Industrial-Grade Reliability: Built for harsh environments, the module operates reliably in temperatures from -30°C to +65°C with humidity up to 95% non-condensing. The robust metal housing provides shielding against electromagnetic interference.

    Frequently Asked Questions

    Q: What does the model number 3500/15 129486-01 represent?
    A: The model number breaks down as follows: 3500/15 = Power Supply Module for the 3500 Series Machinery Protection System; 129486-01 = Legacy High Voltage DC Power Supply Module with 88–140 VDC input.

    Q: What is the difference between the 129486-01 and other 3500/15 power supply modules?
    A: The 129486-01 is the Legacy High Voltage DC version with 88–140 VDC input. Other variants include the Low Voltage DC (20–30 VDC), High Voltage AC (175–264 VAC), Low Voltage AC (85–132 VAC), and Universal AC (85–264 VAC) versions.

    Q: Can I mix different power supply types in the same rack?
    A: The 3500 rack can contain one or two power supplies with any combination of AC and DC. However, Legacy High Voltage DC Power Supplies and PIMs are NOT compatible with the newer High Voltage DC Power Supplies and PIMs. Complete legacy and new main module-PIM sets can coexist in the same 3500 rack with redundant power.

    Q: How does the redundant power supply configuration work?
    A: When two power supplies are installed in a rack, the one in the lower slot acts as the primary supply, and the other in the upper slot acts as the backup supply. If the primary supply fails, the backup automatically takes over without interrupting rack functions.

    Q: What does the Supply OK LED indicate?
    A: The front-panel Supply OK LED indicates when the power supply is operating properly. If the LED is not illuminated, it indicates a fault condition requiring investigation.

    Q: Is this module hot-swappable?
    A: Yes, when redundant power supplies are installed, either power supply module can be removed or inserted without disrupting the operation of the rack. This allows for hot-swap replacement during maintenance.

    Q: How fast can you ship this module?
    A: As this is a stock item, we typically ship within 24 hours of order confirmation via global express services like DHL or FedEx.
