Is it ok to connect four 1200W Power Supply modules to 120V?
Answer:
110V 220V
15 amps x 110 volts = 1650 watts 15 amps x 220 volts = 3300
20 amps x 110 volts = 2200 watts 20 amps x 220 volts = 4400
30 amps x 110 volts = 3300 watts 30 amps x 220 volts = 6600
120V 230V
15 amps x 120 volts = 1800 watts 15 amps x 230 volts = 3450
20 amps x 120 volts = 2400 watts 20 amps x 230 volts = 4600
30 amps x 120 volts = 3600 watts 30 amps x 230 volts = 6900
Using the above mathematical equations you can only run a single 1200W device on either 15 or 20 amp
lines regardless of whether it is 120 or 110 volts. One circuit for each 1200 watt device. The power supplies
will support up to 240V operation for other geographies.
If you have 30 amp, 110 or 120 volt lines you can run two 1200 watt devices.
WARNING
DO NOT use anything that uses the same amount of watts that your circuit can handle, for
example, if you have a 120 volt outlet on a 15 amp circuit the max for that outlet is 1800,
thus you need to stay WELL UNDER that amount. If you use exactly 1800 watts and the
breaker does not trip then the resistance of the wires and connections can heat up causing
a fire. The further from the breaker box the greater the resistance.
volts times amps = watts
watts divided by volts = amps
watts divided by amps = volts
Prior to powering up the system, we recommend that you check your breaker box for the amps for each
circuit, commercial buildings or homes are rated 120 volts (note that double breakers are double the
current, if your household voltage is 120 then double breakers are 240 volts)
IMPORTANT
Electrical equipment or appliances require a set amount of volts, you must make sure you
plug it into the right voltage.
In order to power up the system you would need sufficient circuits. Like other appliances, EB3600-P
expansion unit requires a set amount of volts.
