Description

Overview
  • The SRA100-D1 is an industrial Class B albedometer for measuring global and reflected solar radiation to derive solar albedo.
  • All-digital, modular assembly built from two identical SR100-D1 pyranometers mounted with the AMF03 fixture; intended for PV system monitoring and meteorological applications.


Key features and applications
  • Designed for PV performance monitoring and meteorological stations.
  • Industrial accuracy: spectrally flat Class B per ISO 9060:2018.
  • Modular construction: 2 × SR100-D1 plus AMF03 mounting kit for simplified maintenance and calibration.
  • Digital output: Modbus RTU over 2-wire RS-485 with isolated RS-485 (1.5 kV isolation).
  • Integrated surge protection (standard Level 2, 1 kV) with optional SPD01 upgrade to Level 4 (4 kV).
  • Tested to industrial EMC and immunity standards (IEC 61326-1, IEC 61000-6-2).


Technical specifications
  • Included: 2 × SR100-D1 and 1 × AMF03 (fixture with glare screen and rod).
  • Measurands: global solar radiation and reflected solar radiation; optional albedo and net solar radiation.
  • ISO 9060:2018 classification: spectrally flat Class B.
  • Internal ventilation: no.
  • Heating: no.
  • Mounting: rod diameter 15 mm (15 × 10⁻³ m).
  • Operating temperature range: -40 to +80 °C.
  • Standard cable length: 3 m (surge immunity values measured at this length).
  • Equipment classification: Industrial Equipment.
  • Surge immunity (standard): Level 2, test level 1 kV; with optional SPD01: Level 4, test level 4 kV.
  • Safety compliance: EU Low Voltage Directive (2014/35/EU); USA National Electric Code (NFPA70).
  • Earthing terminal: included on instrument.
  • Digital communication: Modbus RTU over 2-wire RS-485; RS-485 isolation voltage: 1.5 kV.
  • Hardware interface: 2-wire RS-485.
  • AMF03 kit contents: glare screen, AMF03 fixture with rod, conical positioner, M5x12 socket head cap screws (2), M6x8 socket head cap screw (1), M8x12 set screws (2, pre-mounted), mounting instruction sheet.
