Acuity (Acuity Brands) is a major North American lighting and building-technology company that makes LED luminaires, drivers, sensors, controls and system-level software. The company’s portfolio spans architectural and industrial fixtures, embedded luminaire controls and networked platforms — notably the nLight lighting-controls family and related power/relay packs and panels.
Acuity products are widely used in education, healthcare, government, offices, retail, warehousing and manufacturing. Typical applications include zone-level switching and dimming, emergency lighting circuits, luminaire-level controls and projects requiring Buy America(n) options.
The nPP16 series is described by the manufacturer as a workhorse power/relay pack. Key technical points to verify: it converts line voltage to 15 VDC Class 2 bus power, provides a 16 A latching relay for switching, and supplies bus current over two RJ45 ports. Model suffixes matter — D/DS for 0–10V dimming, ER for emergency operation, and EFP for External Fault Protection — and there are voltage, low-temperature and Buy America(n) options.
Always order by the full catalog number and attach the manufacturer spec sheet to your PO. Confirm nameplate voltage, relay rating and plenum rating on-site. Verify bus-power availability for sensors and bridges and include the manufacturer-recommended replacement fuse in maintenance kits. For emergency systems, confirm wiring and interoperability between ER and non-ER units.
Procurement tip: Include the complete model code and the spec sheet in submittals to avoid configuration or compliance issues during ordering and installation.
