What is this?
The DC current sensing switch uses the principle of mutual induction to sense AC, isolate DC current, and output a normally open or normally closed switch signal. Compared with traditional transformers, thermal protectors, etc., it can detect and control more accurately and timely.

What will I get?
Type: normally open/normally closed
Rated load: 0.3A@240V AC/DC
Monitoring current: 0-300A DC
Auxiliary voltage: 8-35V
Response time: Size: 108x22x60mm/4.3x2.4x0.94inch
Package contains: 1pcs x current monitoring relay

Are there any advantages of the product?
LED indication: When the current is lower than the set value, the green signal light is on; when the current is greater than the set value, the red signal light is on;
ABS material: The sensor monitoring relay shell uses ABS fireproof material, which is heat-resistant, high in impact strength and stable in performance.
High performance: the number of switch opening and closing is unlimited, the response speed is extremely fast, and the response time is
How to use it?
Normally open: When the through-current is lower than the set value (the cutoff point is adjustable), the disconnection signal is always output; when the through-current is greater than the set value, the closing signal is output.
Normally closed: When the through-current is lower than the set value (cutoff point is adjustable), the closed signal is always output; when the through-current is greater than the set value, the open signal is output.

What should I notice?
Delay function: The current sensor can be set with a power-off delay, which can be adjusted within 0~100 seconds; clockwise delay increases, counterclockwise delay decreases.
