The RFS5-LA features fully variable control that translates to measurable energy savings and smoother motor operation, reducing wear on incandescent and halogen fan loads. This translates into longer equipment life and lower replacement costs, which is especially valuable in high-turnover facilities. Its 5 A rating at 120 V and 60 Hz ensures compatibility with common small-to-medium fans in control panels while maintaining safe, LOC-based operation. The unit’s memory for power failure means once a desired speed is set, the system returns to that setting after a transient outage, minimizing manual readjustments and downtime. The flush mounting and #16 AWG wire leads simplify installation, speed up commissioning, and improve enclosure space utilization. Polycarbonate housing offers robust impact resistance in industrial environments while maintaining a light almond aesthetic suitable for visible panel applications. These design choices support faster ROI, lower maintenance, and improved compliance with indoor electrical standards. In practice, installers can rely on predictable dimming curves, fewer nuisance tripping events, and a streamlined upgrade path from fixed-speed controls to variable speed technology.

FAQs
The RFS5-LA is designed for flush mounting with wire leads and supports #16 AWG conductors. Install in indoor panels or enclosures, ensuring space for the 2.3 in depth and 3.08 in width. Use a single-pole configuration and maintain compliance with cULus listings. Ensure the device is wired for 120 V, 60 Hz operation and verify proper clearance from exposed live parts during installation.
Fully variable control allows precise adjustment of fan speed rather than fixed on/off operation, reducing unnecessary fan runtime and energy consumption. By selecting an exact speed, systems minimize amperage draw for incandescent/halogen loads, extending motor life, and lowering utility costs. The memory feature also prevents re-acceleration or re-testing after outages, contributing to stable energy performance over time.
Yes. The RFS5-LA is rated for 5 A at 120 V, 60 Hz and is intended for indoor use with incandescent/halogen loads. Its compact, flush-mount design and #16 AWG wiring simplify integration into standard control panels and HVAC circuits, while cULus listing provides compliance for safety in commercial environments.
The RFS5-LA is cULus Listed, highlighting third-party safety certification and conformance to relevant electrical standards for indoor use. This helps ensure safe installation in commercial facilities, facilitates code compliance for building approvals, and reduces risk during audits and inspections.
Upgrading to the RFS5-LA can lower operating costs through energy-efficient, fully variable control and reduced waste heat from fan loads. The memory-on-power feature minimizes manual adjustments after outages, decreasing downtime and maintenance time in panels. The compact, robust enclosure and simple wiring also shorten commissioning times, improving project payback and long-term lifecycle value.
