APsmart RSD-S-PLC Rapid Shutdown Device

APsmart RSD-S-PLC 1000V Receiver (415002) – Rapid Shutdown Device for Solar PV Systems

The APsmart RSD-S-PLC 1000V Receiver (model 415002) is a compact, reliable module-level rapid shutdown device (RSD) designed for residential and commercial solar PV installations. It ensures compliance with NEC 2017, 2020, and 2023 (690.12) requirements by safely reducing voltage on PV source circuits to safe levels within seconds during an emergency shutdown.

This single-input PLC-enabled rapid shutdown receiver communicates via Power Line Communication (PLC) with the APsmart Transmitter-PLC. It continuously monitors a “heartbeat” signal from the transmitter and automatically initiates rapid shutdown when the signal is absent — providing module-level safety without relying on additional wiring or complex setups.

Key Features & Benefits

• NEC 690.12 Rapid Shutdown Compliance — Meets the latest NEC 2017/2020/2023 standards for module-level rapid shutdown, reducing PV system voltage to under 30V within 30 seconds.
• SunSpec Certified PLC Communication — Maintains reliable “heartbeat” signaling with the APsmart Transmitter for dependable operation and simplified system integration.
• Easy Installation — Plug-and-play design with pre-attached MC4 connectors (Stäubli MC4 compatible), short input cable (250 mm), and longer output cable (1200 mm) for flexible module connections.
• Rugged & Weatherproof — IP68 / NEMA Type 6P enclosure rating with over-temperature protection, built for harsh outdoor conditions from -40°F to +185°F (-40°C to +85°C).
• High Compatibility — Works with many string inverters, including SMA-approved systems, and supports up to 1000V system voltage (also available in 1500V variants).
• Manual & Automatic Shutdown — Users can trigger shutdown manually via the Transmitter breaker switch for added safety and peace of mind.
