Model number and parameters:

How to choose the right regulator:

For pure resistive loads, multiply the operating current by three. Example: (2.2kW/220V) * 3 = 30, so the most suitable model will be 40A - SYDH4038VA.

For inductive loads (motors), multiply the operating current by five. Example: (5kW/220V) * 5 = 113, so the most suitable model will be 120A - SYDH12038VA.

Cooling:

To ensure that the models with a capacity of 40A, 60A, 80A, 100A, and 120A do not overheat and operate correctly, a heatsink must be used. Models from 40A and above are supplied with a heatsink.

Do not use models with a rating higher than 40A without cooling!

NOTE:

• Input and output terminals are not isolated, please be careful when using!
• If the load is more than 25A, you must install a heatsink; if it exceeds 40A, you must add a fan.
• If using a transformer, please choose the DTY series.
