Lutron LQR-WPM-6P 6-Zone Wallbox Power Module

Lutron LQR-WPM-6P Wallbox Power Module: 6-Zone Multi-Load Lighting Controller

The Lutron LQR-WPM-6P is a Wallbox Power Module designed to operate directly within high-end automation architectures, including Lutron HomeWorks® QS, legacy GRAFIK Eye® configurations, and commercial/yacht distribution networks. Engineering six independently controllable, forward-phase (triac-based) dimming circuits into a 4-gang enclosure form factor, the module operates across dual-voltage infrastructure (120 V~ and 220–240 V~ nominal at 50/60 Hz).

This unit functions as an addressable local power management hub that eliminates massive, distributed rack footprints while preserving line-voltage switching and smooth, square-law phase-angle dimming down to true cut-off across incandescent, halogen, magnetic low-voltage (MLV), neon/cold-cathode, and approved dimmable LED/CFL installations.

Each LQR-WPM-6P carries onboard intelligence with non-volatile memory, allowing programmed scene thresholds to persist across dirty marine generator bus shifts and shore-to-ship synchronization dropouts. A physical front-panel test button enables local override and manual circuit dry-runs independent of control link processor uptime.

Technical Specifications

Features

1. Continuous Square-Law Dimming Engine: Precision-engineered forward-phase triac controls six independent circuits with smooth human-eye perceived dimming and zero audible transformer buzz.
2. Universal Mains Auto-Compatibility: Rated for line-frequency 50/60 Hz networks operating at either 120 V~ nominal or 220–240 V~ single-phase split/delta topologies.
3. High-Density Unit Wattage: Delivers up to 2,000 W / VA unit capacity at 120 V~ (up to 800 W / VA per single zone) and up to 3,000 W / VA unit capacity at 220–240 V~ (up to 1,200 W / VA per single zone).
4. Fail-Safe Scene Architecture: On-board default scene button and physical status indicators permit immediate manual circuit toggle and emergency override even during total processor link loss.
5. Sub-Panel Space Reclamation: Mounts cleanly in standard 4-gang deep masonry wallboxes, bypassing large centralized breaker-panel enclosure runs in space-constrained bulkheads.

Frequently Asked Questions

Can the Lutron LQR-WPM-6P be used with reverse-phase electronic low-voltage (ELV) drivers directly?

The LQR-WPM-6P utilizes forward-phase triac dimming engines. To control true reverse-phase trailing-edge ELV fixtures without creating inductive ringing or damaging the driver, pair the zone output with a Lutron ELV interface module (such as the PHPM-PA or NGRX-ELVI series).

How do you perform a local circuit test without a running HomeWorks QS processor?

Remove the module’s exterior decorative faceplate to expose the physical default scene button and rotary address switches. Setting the rotary selector to diagnostic test positions allows technicians to force-drive channels to full conduction (100% ON) individually or sequentially, confirming output wiring before the communication loop is commissioned.

What is the purpose of the SSA terminal on the high-voltage terminal block?

The SSA (Security/Special Application) terminal acts as an auxiliary override input. By wiring a maintained or momentary contact closure (such as an emergency panic switch, fire alarm interlock, or master vessel night alarm) to SSA, the unit instantly bypasses current scenes and drives all 6 zones to a programmed safe state or 100% illumination.

Does the LQR-WPM-6P require airflow or an internal cooling fan?

No. The module relies entirely on passive thermal convection dissipation through its cast-aluminum rear casing and vented chassis, generating approximately 82 BTU/hr under full load. Maintain adequate backbox depth (3.5 in / 89 mm minimum) and do not pack line wires tightly over the perimeter cooling louvers.
