Using imported components, high reliability. Built-in WMI filter, anti-interference performance is good. Small DC ripple and high efficiency. Design of soft start circuit, ac surge current limit. Low working temperature, long service life. In the wide voltage range, in line with the global standard. Insulation performance is good, high electric strength. With short circuit, overload, over voltage, protection function. Overload protection: 105% ~ 105% (rated load), Over voltage protection:15%~135%(rated output voltage); short-circuit protection-self-recovery
