By delivering low-ripple regulated DC power directly across the rack backplane, the unit preserves signal signal-to-noise ratios required for accurate field transmitter sampling and cold junction compensation calculations in dense temperature input modules.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the power supply handle dual-redundant configurations within a node rack?\u003c\/p\u003e\n\u003cp\u003eA: When two PS11*C modules occupy designated redundant power slots on the backplane, internal diode-ORing logic balances current distribution under normal operation. If one power supply unit fails or drops voltage, the secondary unit assumes the full 120 W load without interrupting system processing.\u003c\/p\u003e\n\u003cp\u003eQ: What thermal clearance parameters must be maintained during installation?\u003c\/p\u003e\n\u003cp\u003eA: Forced convection or passive dissipation relies on unrestricted airflow through the top and bottom chassis vents. Maintain a minimum vertical clearance of 50 mm above and below the module carrier to ensure operating temperatures do not exceed the +60 deg C rating and trigger thermal protection logic.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eVerify that main AC source power is de-energized and locked out prior to landing physical conductor wires on the terminal block connections. Align the module card guides precisely with the chassis sub-rack slots and push firm against the backplane until the retention screws align with the mounting rail. Ensure the protective earth (PE) grounding conductor connects directly to the rack ground busbar using a low-impedance copper strap to optimize noise immunity. Route field supply cables separately from sensitive high-speed digital communications or low-level instrument signals to avoid electromagnetic interference.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43791471935578,"sku":"PS11*C","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/740.jpg?v=1785982122","url":"https:\/\/www.spareoil.com\/products\/yokogawa-ps11-c-centum-dcs-regulated-power-supply-modules","provider":"SpareOil Automation","version":"1.0","type":"link"}
