When the load is greater than 20A, or the ambient temperature is greater than 40 ℃, please choose a large radiator or install fan-forced cooling to ensure the lifetime of the SCR power regulator and system reliability.
SCR is a large-current product. Please securely lock the main input and output terminals; otherwise, it will cause terminal heating and potential damage.
Equipped with an input buffer function to effectively prevent instant current impact and protect both the SCR and connected loads.
The panel features input and output indicator lights to clearly show the working status and fault information of the SCR at any time.
Frequently Asked Questions (FAQ)
Q:
What should I do if the working load is greater than 20A?
When the load exceeds 20A or the ambient temperature goes above 40℃, it is highly recommended to select a larger radiator or install forced fan cooling to ensure the longevity and reliability of the SCR power regulator.
Q:
Why is it critical to tighten the main input and output terminals?
Since the SCR is a high-current product, loose terminal connections can cause excessive heating at the terminal block, potentially resulting in system damage.
Q:
What protection does the input buffer function provide?
The built-in input buffer function helps effectively prevent sudden current spikes upon startup, safeguarding the regulator and connected loads from damage.
Q:
What are the compatible control input signals for this SCR regulator?
This unit supports multiple common control signals, including 1-5VDC, 4-20mA, and 0-10VDC.
Q:
What are the rated voltage and current options available?
It supports single-phase 380VAC and 220VAC (50-60Hz) rated voltages, with selectable rated currents of 40A, 75A, 120A, 150A, and 200A.
Q:
What environmental conditions are required for optimal operation?
For safe operation, keep the ambient working temperature below 50 ℃ and the surrounding relative humidity under 90% RH.
