Controlling HID Lightingwith Sinewave Technology


2/20

HID Lighting

High Intensity Discharge:

These are arc tube type lamps, whichrequire a ballast to strike an arc insidethe arc tube, which then excites thesurrounding gas to produce very bright

light.

Metal Halideo The White light used in sports venues

High Pressure Sodiumo The Yellow light often used in street lighting

Mercury Vaporo Being phased out, not often used anymore

Why Sinewave?

Dimming Solutions forHIDWere Inadequate

SCR and SSR dimmers will NOT work arc extinguishes

Variac (Auto-transformer) dimmers increase harmonics andshorten bulb life

Hi-Lo controls do not dim HID slowly, resulting in shortenedlamp life, and cannot be retasked

IGBT dimming has been tried, but with high heat gain Different types of HIDs with different ballasts respond

differently

The Sinewave Solution

SineWave Dimmer (Ultra high speed PWM) Adjusts amplitude (voltage) to change power to lamps Monitors and makes adjustments 22,000 time per second Filtered Capacitive ride-through (electronic flywheel) smoothes sine wave Able to reduce power by up to 50% on Metal Halide and up to 70% on Sodium lamps

Applicable to all types of lamps (HID, Incandescent)

Adheres to lamp mfgr. Specso Soft start programo 15 minute warm-up full

powero Slow dim 0.5 V per sec.o Rapid return

Reduces harmonic distortion No harmonics or transients

back on line Smooth electronic ramping, +-

0.1% Infinitely variable

The Sinewave ESDDimmer is an electronic dimmer that varies the voltage

output to the lighting ballasts, which then reduce wattage to the lamps.

Sinewave Dimmers

Sinewave ESD Series Lighting Circuit Dimmers: Dim lighting circuits up to 30 Amps (3600 Watts @ 110 Vac, 8300 Watts @ 277 Vac); Are digital, infinitely variable, and work with standard 0-10 Vdc control signals; Reduce bulb-killing harmonic distortion and can improve power factor; Have no mechanical parts to wear out or require maintenance; Typically show a payback on dimming HID lamps of less than 18 months;

Are installed at the electrical panel, requiring no rewiring of existing lighting fixtures; Qualify for utility rebates and tax credits.

Sinewave ESD Series Dimmers are used in:

Parking Lighting: Structures, Car Dealer Lots, Shopping Mall Lots, Big Box Store Lots Athletic Facilities: Indoor Tennis Courts, Sports Clubs, Gymnasiums, Sports Fields Warehouses: Cold Storage, Trucking Depots, Manufacturing Areas Security & Architectural: Refinery Lighting, Exterior Building Lighting Daylight Harvesting: Big Box stores with skylights, Bubble Enclosures

Sinewave Performance9000 Watt Metal Halide Circuit

Smooth dimming at all levels Volts reduce smoothly from 277 to 195 Vac Amps reduce smoothly from 33 to 23 Amps Watts reduce smoothly from 9000 to 4500 Fairly straight line behavior

Do the math Volts and Amps reduce by 29% Wattage reduces by 50% (what you pay

for) Lux reduces by 40% (plenty of light)

Energy-saving control Set maximum level at 90% (save 10%

energy continuously) Motion detectors automatically ramp up

lights as needed, otherwise 50% Daylight harvesting sensors can also be

used when skylights or windows admitambient light

Frequently Asked Questions

What about color shift? So long as we dim within specs (50% of HID, 70% forFL), there is no noticeable color

shift

Can multiple circuits be connected? Yes. A 30 Amp ESD can handle 2 15 Amp circuits (20 Amp circuit breakers).

o Branch circuit breakers can be provided in the Sinewave enclosure.

HID, FL and Incandescent fixtures can be on the same dimming circuit

What about minimum ft-candle requirements? Codes usually specify the ft-candles during occupancy. The ESD dimmer returns to full

lighting power when needed (occupied).

What effect does the ESD

have on lamp life? Generally the ESD will improve lamp lifeo Reduction of lamp-killing harmonicso Reduction of heat cooler operation of both lamp and ballasto Reduction of lamp restarts. Longer operation per start.


18/20

Is the ESD warranted? Yes. 2 years from date of installation, or 2 years + 1 month from date of shipment

What happens if the power goes off and back on? The ESD shuts off the lamps and then runs its startup program again 15 minute warm-

up before dimming

If the power glitch is less than 10 ms, the ESD remains in operation and rides througho High speed UPS systems can switch without light loss

How can the ESD fail? Loss of control signal the ESD will go to minimum setting (50% for HID or 30% forFL) Failure of control board

o Failure of control circuit the ESD will go to maximum setting (100%)o Failure of control interface to main board the ESD will shut off the lamps

Failure of main board the ESD will shut off the lamps Option for an emergency bypass switch (Murphy switch) for critical applications

What happens ifI connect the ESD to active electronic ballasts? The amp draw will increase as the ESD reduces the voltage no energy savings

o Lamps will extinguish once the voltage has reached the lower limit of the ballasto Circuit breakers or fuses could be tripped due to over-amperage
