Introduction

Plessey’s Hyperion 1750 LED Horticultural Gro light fixture is designed to provide plants ith Photosynthetically

Active Radiation (PAR). This is achieved by supplementing or replacing natural daylight ith an LED generated

light spectrum proven to enhance plant gro th rates and yields. The product is suitable for large scale commercial

greenhouse, hydroponic and research installations and is 1:1 equivalent to a 1000W HPS gro light

The fixture is constructed from die cast aluminium ith a corrosion proof hite po der coating. The light engine

is made up of state of the art LEDs arranged to maximize output and uniformity. With externally mounted driver

and easily removable fan the fixture has been designed to last and is backed up ith a 5 year/25k hour arranty.

Safety

The Hyperion fixture does not radiate harmful avelengths of light but like many high po er artificial lights, users

should not look directly at the fixture hilst the light is on.

Care must be taken hen assembling, fitting or handling to prevent personal injury or damage to the product.

This light fitting must be installed by a competent person in accordance ith the local Building and Electrical

Regulations.

Plessey cannot accept any liability for loss, damage or premature failure resulting from inappropriate use. Plessey

can advise on installation requirements including ho to achieve the desired amount of light and uniformity.

Should the fan fail or the fixtures ability to actively cool be inhibited the LED Printed Circuit Board (PCB) ill run

hotter. This increase in temperature is registered and fed back to the driver. Upon hitting a certain safety

threshold the driver ill reduce the po er to the PCB. This causes a noticeable drop in light output to approx.

1000umol/s depending on spectrum and protects the fixture from overheating. The driver has a built-in thermal

protection so should it overheat the po er ill be cut.

ight Spectrum / Intensity

The Hyperion comes ith a set of standard Spectrums hich cover most commercial greenhouse applications.

Plessey ill 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.

The intensity of light received by the crop is very important in achieving optimum gro th. The number of lights

and their distance from the crop ill affect this significantly. Plessey’s agronomy & engineering support ill

recommend an intensity level based on the client’s crop and gro ing environment.

Dimensions

Belo image of standard fixture including primary bracket. It is important clients provide relevant safety

information on equipment and material ithin 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 allo s for this

in its design.

295867 v.1

Mounting Position / Uniformity

Plessey has adopted a similar approach to conventional HPS light fixtures ith the fixture being designed to ork

ell from existing greenhouse structures like Trellis sections. Choosing to fit Hyperion fixtures to trellis offers

significant advantages by reducing shading, reducing install costs and providing containment for iring. The

dimensions of a client’s greenhouse and in particular bays contained ithin it ill affect the uniformity. Hyperion

can also be mounted to C Profile or other metal ork hich provides gro ers greater flexibility.

The Hyperion product range contains LEDs ith a ide 120 degree beam angle (FWHM) hich orks very ell at

distributing light over large areas. Based on the determination of Spectrum / Intensity and preferred mounting

position Plessey ill create a lighting simulation hich ill determine the number and position of the fixtures.

As an option, Hyperion can be fitted ith a reflector on any of the 4 sides of the unit.

The reflector can be attached to units at the edges of an installation to reflect the light back into the main lit area,

avoiding light spilling outside the glasshouse or into a different compartment/area. This helps maintain light

uniformity over the hole lit area

295867 v.1

Mechanical Considerations

Once the position and quantity of the fixtures has been decided the client must check ith greenhouse installers

and engineers that the integrity of the structure can ithstand the overall and point load brought to bear by the

installation of the fixtures.

A suitable means should be chosen to mount the fixture. Belo 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,

atering systems and automation equipment.

Electrical Connection Considerations

The Hyperion gro light is supplied ith an external driver hich is mounted on the hanging bracket supplied ith

the fixture. The fixture has been optimized to run on a t o phase input from a 3 phase 400V supply. Ho ever, the

product can operate ithin a ide range of supply voltages. Ask for more details.

The fixture is pre ired ith a Wieland male connector for attaching to

the greenhouse lighting supply iring as per the customers requirement.

See image opposite.

For ne Installations Plessey recommends the Wieland (Green) 96.032.4055.7

Ho ever, for HPS replacement a Wieland (Black) 96.032.4053.1 may be

more suitable.

The greenhouse lighting supply iring should be terminated ith the

corresponding connector hich is Wieland RST20i3 400v 3 pole female connector

(green) to plug into the driver Wieland part no. 96.031.4055.7 or 96.031.4053.1 if

using the Wieland (Black) connector system. See image opposite. The position of

the female connector should be in close proximity to the position of the fixture and

provide adequate strain relief / support for the fixture iring.

For ne build large installations, it is recommended that a pluggable iring system is pre-

installed. Pre-made lengths of po er cable ith a female connector are available.

Wieland part number 96.232.1035.7 through to 96.232.8035.7 (8x variants from 1m to

8m) See image opposite for an example of a pre-made cable.

Plessey can assist installers ith cabling determinations and supply requirements.

Important Information

The Ingress Protection of any termination performed by the client must preserve the ingress protection of the

fixture in order to maintain product arranty.

It is important in large installations that the pairs of phases are s apped and evenly distributed throughout the

installation to avoid overloading one phase of the supply.

Once installed, free from all packaging materials and connected to the fixed ring system the product can be

s itched on ith no further commissioning.

295867 v.1

Electrical Design Considerations

Running Current = Input Po er / Supply Voltage

For example if supply voltage is 400V

684 / 400 = 1.71A

A corrective device and supply cable should be chosen by applying

It > In > Ib

Where,

It = Cable current carrying capacity, In = Protective device rating, Ib = Circuit design current

Hyperion’s are supplied ith a state of the art Po er Supply referred to as a driver. The primary job of the driver

is to convert the high voltage ac supply into a lo er voltage dc supply suitable for the Light Emitting Diode’s

(LED’s). It is important that it does this efficiently so the driver has circuitry hich corrects po er factor. The

consequence of this po er factor correction is that the fixture has substantial capacitance hich causes a very

short but significant inrush current on start up. This can be up to 40A for 1100 μS measured at 50% of peak. See

belo .

Hype ion In ush cu ent wavefo m

It is important therefore hen determining hich circuit breaker to use that it is suitable for the number of

fixtures it is going to protect.

295867 v.1

The follo ing 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 ired across 3 phases as detailed belo

Example final ci cuit design

In this configuration one 3 phase MCB is protecting 3 circuits so e can treat the inrush problem as 5 fixtures per

phase.

Ho ever, e need to ork out (Ib) per phase

Ib per phase = Fixture x Current per Fixture

∛

Ib = 15 x 1.71

∛

In per Phase = 14.8A

Therefore, a 20A MCB is suitable to protect the design load. Providing the cable has suitable current carrying

capacity.

Manufacturers for protective devices provide documents relating to tripping curves under IEC/EN 60898-1 and

IEC/EN 60947-2 standards. Ho ever, due to the very brief nature of capacitive inrush currents these standard

curves do not provide sufficient detail about the magnetic portion of the trip.

Installers should request manufacturers provide tripping curves for high inrush currents that appear during the

first milliseconds of operation.

295867 v.1

The response of the 20A Schneider Electric MCB can be evaluated from the follo ing graph.

MCB Manufacturers instantaneous response curve

The fixture has a potential inrush of 40A for 1100 μS therefore the circuit has a potential inrush of 5*40A = 200A

for 1100 μS per phase. It ould suggest that a 20A 3 phase MCB ith type C curve is capable of handling up to

19*40 = 760A in this time period.

This is an example and should not be treated as the rule. It is very important that installers check ith circuit

protection manufacturers that the chosen circuit protection is suitable for their design.

It is also important that installers consider volt drop hen determining loads on cables and cable size.

This is particularly important in greenhouse installations here the potential for circuits covering long distances

is common.

Hyperion drivers are capable of orking ith a ide range of voltages but installers should design to local

regulations and limits. IEC 60364 provides guidance and limits on volt drop provision.

Hyperion Drivers have been independently tested and comply ith follo ing Electromagnetic Compliance

legislation;

EMC Emissions Compliance to EN55015, EN61000-3-2 Class C (@ load≧50%); EN61000-3-3, FCC Part 15 class B

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 a e intended to p ovide guidance to installe s but diffe ent installations in diffe ent egions may equi e alte native app oaches. Plessey will

make eve y effo t to assist in establishing a feasible design.
