Sinewave Energy Technologies

• Controlling HID Lighting
• with Sinewave Technology

2
HID Lighting

• High Intensity Discharge
• These are arc tube type lamps, which require a
  ballast to strike an arc inside the arc tube,
  which then excites the surrounding gas to produce
  very bright light.
• Metal Halide
• The White light used in sports venues
• High Pressure Sodium
• The Yellow light often used in street lighting
• Mercury Vapor
• Being phased out, not often used anymore

Why Sinewave?

• Dimming Solutions for HID Were Inadequate
• SCR and SSR dimmers will NOT work arc
  extinguishes
• Variac (Auto-transformer) dimmers increase
  harmonics and shorten bulb life
• Hi-Lo controls do not dim HID slowly, resulting
  in shortened lamp 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
The Sinewave ESD Dimmer is an electronic dimmer
that varies the voltage output to the lighting
ballasts, which then reduce wattage to the lamps.

• Sine Wave 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. Specs
• Soft start program
• 15 minute warm-up full power
• Slow dim 0.5 V per sec.
• Rapid return
• Reduces harmonic distortion
• No harmonics or transients back on line
• Smooth electronic ramping, -0.1
• Infinitely variable

Sinewave Dimmers

• Sinewave ESD Series Lighting Circuit Dimmers
• Dim lighting circuits up to 30 Amps (3600 Watts _at_
  110 Vac, 8300 Watts _at_ 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.

Frequently Asked Questions

• What about color shift?
• So long as we dim within specs (50 of HID, 70
  for FL), 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).
• 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 life
• Reduction of lamp-killing harmonics
• Reduction of heat cooler operation of both lamp
  and ballast
• Reduction of lamp restarts. Longer operation per
  start.

18
Frequently Asked Questions

• 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 through
• 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 for FL)
• Failure of control board
• Failure of control circuit the ESD will go to
  maximum setting (100)
• 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 if I connect the ESD to active
  electronic ballasts?
• The amp draw will increase as the ESD reduces the
  voltage no energy savings
• Lamps will extinguish once the voltage has
  reached the lower limit of the ballast
