Checking scheme: test whether the input voltage is normal from the input terminal on the bottom of the product. It is recommended to replace the connecting wire in good condition. The end of the connecting wire should be clamped tightly to avoid bad contact.
Long start - up delay
In the production application, the startup delay of normal connection may be mainly caused by:
Busbar voltage is low, resulting in small starting current, product internal charging is slow
Checkout scheme: the input bus voltage can be detected with a multimeter to confirm whether the input voltage is within the rated range of the product. It can be compared with the input voltage range marked on the product label paper to check whether it is within the range of specifications. If it is used beyond the specification, it is recommended to use products with wider input voltage range of our company.
No output/output variation at startup (hiccup/jump)
