Technical Support
Make sure you have accurate equipment information you need to run.
- 20 HP Wide Belt Sander - 460 Volts
- 7.5 HP Dust Collector - 230 Volts
- 10 HP Shaper - 230 Volts
Do you have enough Utility Power?
At your main breaker panel is a good indication how much service you have, thebest more accurate is finding out what size utility transformer you have feedingyour building.
Determine Utility Power
Utility transformers vary from size, from 15 KVA,25, 50 100, 167, 300 and so on for single phase utility power. The KVA number is the true amperage you have available.
NOTE: Ask a sales representative help you for HIGHvoltage 460-480 Volt input Single PhasePower.
Saftey, State or Local Regulations?
Not only following state or local laws, it is important saftey is considered, We go beyond NEC and UL Listing, standards to make sure your safety is first, We offer UL Listed Phase Converter along with many other saftey products and systems, not all phase converters must be UL listed, but check with yourlocal and state code or electrician.
LOAD TYPES
- Easy load: The phase converter can be the same size as the motor.
- Medium load: The phase converter should be 1.5 times larger than the motor.
- Hard load: The phase converter should be double the size of the motor.
- Very hard load: The phase converter should be 2.5 times larger than the motor
- Multiple loads: This should be sized by Phoenix Phase Converter agent.
- Resistive load: The hardest type of load FLA amps x 1 = the HP of the Converter.
LOAD TYPES EXPLAINED
- Easy Load: Typically machinery that have a low inertia during start up, free spinning, but not limited to this. Such as saws, drill press, milling machines, ect.
- Medium Load: Requires a bit more energy to start, not many equipment in this load type. Such as some mixers, smaller lathes,ect.
- Hard Load: Most common load type, includes lathes, CNC machines, pumps, Press Brake, Wide Belt Sander ect.
- Very Hard Load: Also common, example would be a Air Compressor, HVAC, Fan, Hydraulic press, ect..
- Multiple Load: Has to be sized by the largest load first and then calculated by a professional, typically the total HP of all your equipment running at once will be the size of the phaseconverter, this has a lot of variants.
- Resistive Load: This type of load is your biggest demand from aphase converter, even that a phase converter max resistive load is higher then the selected unit, the rule of thumb to keep abalanced voltage is use 1 HP for every amp of resistive load.
Determine the Converter Size
Phase converter size can be sizes properly after we determined the load and the power supply. Some cases your load can be wired for only high voltage 460-480 Volts, which will require a transformer after the phase converter.if you don’t have enough power to start the size of the phase converter needed for your equipment, but you have adequate power for your running load of yur equipment, our DualZone Phase Converter can be utilized. RULE OF THUMB: the KVA number needs to be larger than the HP of the phase converter.For example if you have a 50 KVA (200amps) single phase service you cannot start a 60 HP converter, but you can use our DualZone 30/60, to get to your 60 HP of total converter. Please always have a sales representative help you size the phase converter since thereare many varibles. NOTE: you can always expand your converter by pairing two or even more converters together at any time.
Support is our Specialty
We can offer custom built converter, Did you know you can add Phase Converters together? example if you have a 30 HP converter you can add a 20 HP converter and make it a 50 HP Converter?
