Information About 406000
The 406000 is part of APsystems’ Rapid Shutdown System (RSS), delivering power line communication (PLC) signals to compatible RSD-S-PLC shutdown units. Engineered for grid-tied PV installations, the Transmitter-PLC helps maintain normal operation during grid presence and triggers rapid shutdown when de-energized. It features a dual-core design for robust signal transmission and offers compatibility with both residential and commercial power systems via optional external power supplies. The unit is SunSpec-certified and ensures streamlined compliance with 2017 NEC 690.12 requirements.
Key Features:
- Dual Core Design: Enhances signal strength and stability for extended system reliability.
- SunSpec Certified: Supports standardized communication protocols for rapid PV module shutdown.
- NEC 690.12 Compliant: Meets 2017 National Electrical Code specifications for safety.
- No Power Supply Included: Can be paired with optional 85–264VAC (residential) or 180–550VAC (commercial) supply.
- Failsafe Operation: Signal stops automatically upon AC power loss, triggering shutdown.
- Heartbeat Signal Functionality: Maintains PV module activity while active; shuts down when signal is lost.
- Compact Construction: Supplied as a plug-in PCBA with 29 mm ID ferrite core rings.
- System Integration: Designed for use with APsmart RSD-S-PLC units in PV installations.
The 406000 delivers the reliability and compliance required for safe, code-adherent PV system operation.
