Summary of Contents for Plessey Hyperion

Page 2: Specification Summary
Photosynthetic Photon Flux and connected electrical load are subject to tolerance of +/- 10%. For the purposes of this document Photosynthetic Photon Flux is measured between 380nm – 780nm with each wavelength weighted equally. The Hyperion 1750 has been tested by an accredited independent laboratory to LM-79-08, (BS) EN 13032-4:2015 and CIE S025:2015 test standards. Information can be supplied upon request.
Page 3: Fixture Components
The Hyperion comes with a set of standard Spectrums which cover most commercial greenhouse applications. Plessey will provide Agronomy support to ensure the optimum spectrum is selected for any given crop. Plessey can also provide customised spectrums for volume orders should this be required.
Page 4 Dimensions Below image of standard fixture including primary bracket. It is important clients provide relevant safety information on equipment and material within close proximity to the installed fixtures. Energy, light and other greenhouse screens could affect the safe mounting height of the fixture so its important brackets allows for this in its design.
Page 5 C Profile or other metal work which provides growers greater flexibility. The Hyperion product range contains LEDs with a wide 120 degree beam angle (FWHM) which works very well at distributing light over large areas. Based on the determination of Spectrum / Intensity and preferred mounting position Plessey will create a lighting simulation which will determine the number and position of the fixtures.
Page 6: Mechanical Considerations
A suitable means should be chosen to mount the fixture. Below are illustrations of common mounting methods Plessey has provided to its customers. These can be adjusted and modified to meet customer requirements. Consideration should be given to existing or planned glasshouse infrastructure like light and energy screens, watering systems and automation equipment.
Page 7 Electrical Connection Considerations The Hyperion grow light is supplied with an external driver which is mounted on the hanging bracket supplied with the fixture. The fixture has been optimized to run on a two phase input from a 3 phase 400V supply. However, the product can operate within a wide range of supply voltages.
Page 8: Electrical Design Considerations
It = Cable current carrying capacity, In = Protective device rating, Ib = Circuit design current Hyperion’s are supplied with a state of the art Power Supply referred to as a driver. The primary job of the driver is to convert the high voltage ac supply into a lower voltage dc supply suitable for the Light Emitting Diode’s (LED’s).
Page 9 The following example is representative of a typical electrical lighting circuit for a greenhouse. In this example the chosen circuit protection is a three phase MCB 20A Type C from Schneider Electric. The circuit has 15 fixtures wired across 3 phases as detailed below Example final circuit design In this configuration one 3 phase MCB is protecting 3 circuits so we can treat the inrush problem as 5 fixtures per phase.
Page 10 EMC Immunity Compliance to EN61000-4-2,3,4,5,6,8,11, EN61547, light industry level (surge immunity Line-Earth 8KV, Line-Line 4KV) Note: The above steps are intended to provide guidance to installers but different installations in different regions may require alternative approaches. Plessey will make every effort to assist in establishing a feasible design.
Page 11: Installation
Installation The erection method for any Hyperion variant will ultimately depend on the bracket solution but the hanging concepts are broadly the same. The fixtures arrive boxed / crated. It is recommended that the polythene bag is kept on the fixture until the point of installation.
Page 12: Maintenance
Maintenance The Hyperion 1750 has been designed so that both the driver and fan are user replaceable. 295867 v.1...
Page 13 295867 v.1...
Page 14 Hyperion has been designed to have its LED driver externally mounted. This has a number of benefits including cooling, lifetime and allowing it to be user replaceable. Typical symptoms of driver failure include fixture not turning on, fixtures turning on for a short while then turning off or fixtures flashing on and off.

Page 16: Other Failures
Other Failures The design of the Hyperion LED Printed Circuit Board provides for an element of fault tolerance. If a single LED were to fail the remaining LEDs will be able to operate normally with minimal impact on fixture output.
