the use of precautions:
1. No matter in any case, no-load is allowed (no-load refers to the output port without
any load).Once the power is turned on, the board will emit high-frequency noise, which
will cause the MOS tube to be completely damaged and cannot be repaired.
2. It must be noted when using a switching power supply, because a high-power
3. This circuit has strict requirements on power supply. The 12V power supply must use
more than 500W power supply, 24V is greater than 1200W, 36V is greater than 2000W,
and 48V is greater than 2600W (recommended working voltage is 48V);
4. No matter the voltage is used, as long as the operating current is lower than 50A, the
circuit will not be burned out. Therefore, a 50A fuse can be added to protect the circuit
during high-power operation.
5. The working voltage must not be lower than 12V.
6. The input power supply is recommended to be DC48V50A. Do not use AC power!!!
7. Since the machine uses the bottom air intake for air cooling, the machine uses the
object to pad the machine at least 30mm or more to avoid damage to the machine.
use the steps:
1. Make sure the air switch is off!
2. Connect the external water pipe to the cold water prepared in advance, and fasten the
heating ring to the heating ring connector with a wrench.
3. Turn on the external power supply (not push the air switch), the water pump fan and
the power meter are running. If any one of the cooling fan and the water pump does not
work, stop using the contact manufacturer. If the voltage on the power meter is lower
than 12V, check the external DC power supply. Whether it is fault
4. Push the air switch, the heating machine works, pay attention to observe the
indication of the power meter and the temperature of the main board during work.
When the working current is greater than 50A, do not continuously exceed 30 seconds.
The long-term use guarantees that the current is lower than 50A, when the motherboard
temperature is greater than 85 degrees Celsius.Please turn off the machine
5. When shutting down, follow the air switch first, and then disconnect the external DC
power supply after one minute.
