200-480V high bay solutions

Many LED & conventional lighting products are designed to derive power from standard 120V or 240V power sources. Power supplies for these devices (typically called “Drivers”) may be designed to operate at either of these voltages, or often, at any voltage between 100-277V (universal input supplies).

The challenge

Many commercial & industrial installations receive primary power at 347V (in Canada) or 480V (US), which often exceeds the rated input voltage for most lighting products. It is hazardous to operate a device beyond its rated voltage & is not acceptable by the local electrical authority. LED High Bay Light is the most popular light used in industrial applications. That’s why many electricians in North America are looking for a 347V or 480V input High Bay Light. Note: Electrical supply in both Canada and the US typically operates at 60 Hz (frequency).

Nominal standard supply voltages in Canada
Nominal Supply Voltage – CanadaTypical Uses
600V 3-phase (line-to-line)High-Power Industrial and Commercial loads
347V 3-phase (line-neutral)High-Power Industrial and Commercial loads
208V 3-phase (line-to-line)Commercial, Industrial and some large Residential loads
120V 3-phase (line-to-neutral)Commercial, Industrial and some large Residential loads
240V split phase (line-to-line)Residential large loads
120V (line-to-neutral)Residential, common use

Note:  Nominal standard supply voltages in the USA

The U.S. has many similarities with Canada on lower voltage side (208/120V 3-phase & 240/120V split-phase supply) but differs on the higher voltage side as follows:

Nominal Supply Voltage – U.S.Typical Uses
480V 3-phase (line-to-line)High-Power Industrial & Commercial loads
277V 3-phase (line-to-neutral)High-Power Industrial & Commercial loads

What happens if the supply and fixture voltages are incompatible?

A supplementary device that reduces or “steps” the voltage down is required.  This is when an installer would use a step-down autotransformer.

Autotransformers are a simple and reliable style of transformer consisting of a single coil wound around a steel core that takes a higher voltage input (e.g. 347 or 480V) and “steps it down” to a lower voltage (e.g. 240V or 120V).

Tip: These transformers must bear Safety Certification markings to show compliance with safety standards to the local electrical inspection authority.

Don’t want to use autotransformers? Then try our 347V or 480V input High Bay Light.

Fireflier provides a much easier solution which allows you to use our high bay light directly with 347V or 480V input voltage without transformers.
