Rangkaian Fuse Sekring Elektronika.

FUSE SEKRING electronic designed to operate on 230V AC with an adjustable trip current.
When the current “SEKRING LISTRIK RUMAH” through the load exceeds a level determined by the position of the wiper on
the 1k wire-wound pot, this circuit cuts off the load immediately. If S1 is open,
the range is approximately 300-650 mA, and 0.8-2A when it is closed.

Note:

* This circuit connects directly to 220-230V AC which can be lethal! Please do not attempt to build any of the circuits/projects unless you have the expertise, skill and concentration that will help you avoid an injury.

Datasheet LCD 4 Digits SP521PR


DATASHEET 4 DIGITS LCD SP521PR based digital thermometer, it is a “LAPTOP” possible to measure from -40
to +150 degree celsius. It uses S8100 or 1S1588 as thermal sensor.
The power consumption is very small and it is possible to operate about 3 months continuously
from a 9-V cell.

This is the TN (Twisted Nematic)-type liquid crystal display. It is possible to 4 digits
display but the display of the maximum figure is only “1”. It isn’t possible to work
continuously in the direct current. However, when applying the about 5-V DC voltage between
the backplane (common) and the terminal, the color of the segment which corresponds can be
temporarily changed to the black. With this, the correspondence of the terminal and
the display segment can be confirmed.
