| Keep a low profile on the grid by reducing your peak power consumption footprint |
When magnetic ballasts are powered up they consume a lot more energy as they build up
their magnetic field than they do during their normal operation. This current surge is
known as inrush. Inrush usually lasts milliseconds but it's quite intense, up to ten times or
more than the normal operating consumption. A 1000 watt ballast can easily spike to
10,000 watts or 42 amperes at 240vac during power up. Maybe not long enough to trip the
circuit breaker but long enough to be read by the new smart hydro meters.
Consider 4 ballasts of 1000 watts. When all 4 ballasts are ignited at once they can spike
to 40,000 watts. At 240vac that's 167 amperes or 900% more than the 17 amperes
required to normally operate the ballasts. If the Hydro transformer that supplies the power
is close to capacity the inrush can last long enough to trip breakers and be very noticeable
by neighbours powered by the same transformer as the voltage drops substantially while
the ballasts build up their magnetic fields and the transformer recovers.
To drastically reduce inrush you can ignite ballasts individually. 4 ballasts lighting
individually reduce the inrush from 167 amps to 42 amps or 75%. 24 ballasts lighting
individually reduce the inrush from 1000 amps to 42 amps or 96%.
The On Delay allows for each contactor or relay to power up one at a time reducing inrush
and your peak power consumption footprint on the grid to a minimum. Low cost protection
for maximum security. Can also protect your lamps against hot restarts in the event of brief
power interruptions.
Each On Delay is adjustable from about 1 second to 10 minutes. For quick power up set
each On Delay at under 1 minute. For HPS hot restart prevention set each ON delay at
about 2 minutes. For Metal halide hot start prevention set each On Delay at about 4
minutes.
