APsystems RSD-D-20 (MC4) Rapid Shutdown Device | Dual Input | NEC & SunSpec Compliant

APsystems RSD-D-20 (MC4) Rapid Shutdown Device | Dual Input | NEC & SunSpec Compliant

Downloads:

Ensure full solar system safety and code compliance with the APsystems RSD-D-20 (MC4) — a dual-input, module-level rapid shutdown device (RSD) designed for maximum compatibility and efficiency in residential and commercial PV systems.

Code-Compliant Solar Safety

Meet and exceed NEC 690.12 requirements (2017, 2020, 2023) with this UL1741-certified RSD. The RSD-D-20 (MC4) ensures system shutdown when the Transmitter signal is absent, providing essential protection for rooftop and ground-mounted solar installations.

Dual-Input Channel for High-Density Arrays

Equipped with dual MPPT channel support, this MC4 rapid shutdown unit simplifies wiring and improves compatibility with modern PV modules, inverters, and split-phase solar inverters.

SunSpec Compliant & Smart Integration

Built to integrate seamlessly with SunSpec-certified inverters, the RSD-D-20 maintains operation via PLC-based heartbeat signal and allows manual shutdown via transmitter switch for added control and flexibility.


Key Features:

  • NEC 2017/2020/2023 (690.12) compliant

  • Dual input channels for 2 PV module strings

  • SunSpec & PLC communication compatible

  • Works with up to 1500V systems

  • IP68 / NEMA 6P waterproof rating

  • Stäubli MC4 connectors for secure DC wiring

  • Supports manual or automatic shutdown

  • Designed to reduce fire risk during suppression efforts


Specifications:

  • Model: RSD-D-20 (MC4)

  • Max Current: 20A per channel

  • Voltage Range: 8–65V DC input / 16–130V DC output

  • Short Circuit Current: 25A

  • Cable Length: Input 0.5m / Output 2.4m

  • Operating Temp: -40 °C to +75 °C

  • Certifications: UL1741, CSA C22.2 No. 330-17, IEC/EN62109-1, FCC Part 15


Ideal For:

  • PV system integrators

  • Solar contractors & installers

  • Off-grid & grid-tied solar systems

  • SunSpec-compatible inverter systems

  • Module-level solar rapid shutdown applications


What’s Included:

  • 1x APsmart RSD-D-20 (MC4) unit

  • Stäubli MC4 PV-KBT4 & KST4 connectors

  • Integrated 2.4m output cable


Stay compliant. Stay safe. Choose the APsystems RSD-D-20 MC4 rapid shutdown device for your next solar installation.
