Power your 208-240V
Diamond H Company LLC doing business as Quick220 Electrical Systems, since 1994
Businesses sometimes find their work requires the use of a large format, 208-240 volt printer, but don’t have a 208-240 outlet available. A Quick 220®system will supply this voltage at up to 20 amperes, resulting in fast setup and overcoming electrical limitations of the work site. Generally, a package based on the Quick 220®system A220-20D is chosen as the power source for these large print systems.
Heating Duct Cleaning Vacuums
Mobile HVAC duct cleaning services can use more efficient 208-240 volt vacuums even if there is no 208-240 volt outlet. Just use aQuick 220®system connected to ordinary 120 volt outlets. You get a more thorough cleaning in less time.
Do I need to convert my electricity from 120 volts to 208-240 volts to operate my appliance?
Not sure what product or voltage you need? Try out out product selection to help find the right product for you by answering a few simple questions.
Find the voltage(s) for the appliance shown on its “rating label”. It is on device’s body or on the power supply module that is part of a detachable power cord. The “rating label” usually has the manufacturer’s name, model number, and electrical specifications. Sometimes, it is molded into the body of the appliance.
If the label reads “208-240” or “230” or a number close to these values, followed by V or VAC or Volts, then you need a voltage converter.
“100-240” or numbers showing a large difference between the 2 values
No, you do not need a voltage converter!
If the label reads “100-240” or numbers showing a large difference between the 2 values, followed by V or VAC or Volts, AND your electricity voltage falls between the 2 numbers, you do not need a voltage converter. Your appliance was made to operate on power from many different countries. You may need to change the plug or use a plug adapter available from numerous web stores.
What kind of voltage converter is needed?
For this you need the “amperes” (A or amps) or the “watts” (W) from the appliance’s rating label. Sometimes “volt-amperes” (VA) is given. While not exactly the same as watts, one can use volt-amperes in place of watts for deciding the type of converter to choose.
Step Up Transformer
If the rating label shows less than 5 amperes or 1200 watts, a step-up transformer is usually recommended. These are available from numerous sources on the internet.
Quick 220® System (15 A)
If the rating label shows 12 amperes or 2880 watts, or less, the Quick 220® 15 ampere, A220-15D is recommended. Twelve amperes is a continuous use rating.
This system can be extended to draw 15 amperes or 3600 watts for up to 3 hours.
The Quick 220® 15 ampere system will also accept a draw up to 50 amperes momentarily for the starting of motors, electronics, and similar items.
Quick 220® System (20 A)
If the rating label shows 16 amperes or 3840 watts, or less, a Quick 220® 20 ampere, A220-20 is recommended. Sixteen amperes is a continuous use rating.
This system can be extended to draw 20 amperes or 4800 watts for up to 3 hours.
The Quick 220® 20 ampere system will also accept a draw up to 50 amperes momentarily for the starting of motors, electronics, and similar items.
As you approach the limits of the various converters above or if you do not have the 120 volt circuits available which will support them, we advise having new circuits installed.
Which 20 Ampere Quick 220® System should I choose – A220-20D or A220-20L?
These items are identical except for the 208-240 volt outlet. Choose the model Quick 220® System based on the type of plug on your device.
The “D” version accepts straight blade 208-240V plugs commonly found on air conditioners, electronics, office equipment, and EV charge cables. These are technically known as NEMA 6-15 or NEMA 6-20 plugs.Shop Quick 220® System A220-20D
The “L” version accepts twist-locking 208-240V plugs commonly found on maintenance equipment where there is pulling on the power cord. This is known as a NEMA L6-20 plug.Shop Quick 220® A220-20L
If you have a NEMA L6-30 plug AND the ampere demand of your appliance is less than 20 amperes, your appliance may be powered by the Quick 220® A220-20L using the CORD109 adapter.Shop Quick 220® A220-20L
Quick220® Electrical Power Requirements
The Quick 220® Power Supply operates with the two most common 120 volt electrical systems in the US and Canada. The Quick 220® power supply needs:
• Two 120V grounded outlets on two different electrical phases.
• Outlets wired correctly.
• No GFI’s (ground fault interrupters) controlling the outlets. (The Quick 220® System will turn off a GFI outlet.)
• The ampere draw of your 208-240V device must be within the ampere capacity of the building’s circuit breakers and the Quick 220® system.
To check if outlets are wired correctly, use an outlet tester. Our TEST001 is an example. If the tester has a push button, it will also test to see if a GFI controls the outlet.

Electric Vehicle Charging
Quick 220® Systems will charge your electric vehicle 2 to 5 times faster than 120 volt charging. The actual charging improvement is dependent upon the vehicles charge system and the 120 volt circuits available to you.
We recommend the Quick 220® System A220-15D, which will supply 240 volts at 12 amperes from residential 120 volt electrical service. The improvement to your charging rate is best determined from the chart on the Tesla web site.
• For 120 volt charging, select the charge rate for the “5-15” adapter on the Tesla chart.
• For 240 volt charging with the Quick 220® A220-15D, select the charge rate for the “6-15” adapter on the Tesla chart.
Multiply the two numbers by 10 to simulate a 10 hour charge and compare the difference.
The Quick 220® system recommendations depend on the manufacturing date of your charge cable.

North American Voltage Ranges
In the United States and Canada, the electrical power supplied to most homes is a split-phase system. That power enters your home at about 240 volts. This 240 volts is split at the main circuit breaker panel into two 120 volt halves, called phases. The 120 volt level is commonly referred to as 110, 115, 120, or 125 volts and is used for lighting and ordinary outlets. Similarly, 220, 230, 240, and 250 volts are used to describe the higher 240 volt level. This higher voltage range supplies larger appliances such as clothes dryers, large air conditioners, and electric vehicle charging. But why all the different numbers?
