single phase cur oltage protector

How the single-phase current voltage protector works

The operation of the single-phase current voltage protector in jbh is as follows: if the measured values of voltage and current exceed the set range, the device will cut off the output power according to the set time, and if the error is fixed, it will restart the output power after the set time. It connects

Ranges and adjustable values of JBH single-phase surge protector

The range and values of the JBH voltage protector are adjustable. Below is a complete table including the description of the parameters; To get to know the product and take advantage of its features.

parameter	description	Domain	Assumption	Description
t	Initial setup time	1…500 seconds	60	In order to protect the equipment from the sudden disconnection and disconnection of the city’s electricity, the initial start-up time is considered, which causes the protective relay to connect with a delay when the electricity is connected.
U1	The amount of overvoltage	230 … 300 volts	245	It determines the amount of acceptable overvoltage, which according to the standard can be up to 255 volts, but the default of this device is 245 volts.
tU1	Time to make a cut off the addition of a tag	0.1 … 30 seconds	0.1	It refers to the time when after the occurrence of overvoltage, the protector cuts off, and it is better to set it in the shortest possible time
U2	Overvoltage recovery amount	225 … 295 volts	240	It refers to the voltage that allows connection after overvoltage by reaching this protective voltage, which is set to 5 volts lower than overvoltage according to the standard.
tu2	Overvoltage connection delay time	1 … 500 seconds	60	It refers to the time when after the occurrence of overvoltage, the protector allows reconnection, which should be set above 1 minute.
U3	The amount of voltage drop	140 … 210 volts	200	It refers to the voltage that allows connection after the voltage drop occurs, reaching this protective voltage, which is set to be 5 volts higher than the voltage drop according to the standard.
tU3	Voltage drop cut-off operation time	0.1 … 30 seconds	3	It refers to the time when after the occurrence of overvoltage, the protector allows reconnection, which should be set above 1 minute.
U4	Voltage drop recovery amount	145 … 215 volts	205	It refers to the voltage that allows connection after the voltage drop occurs, reaching this protective voltage, which is set to be 5 volts higher than the voltage drop according to the standard.
tu4	Delay time in voltage drop connection	1 … 500 seconds	60	It refers to the time when after the voltage drop occurs, the protector allows reconnection, which should be set above 1 minute.
c	Overload amount	1 … 63 amperes	32	Determines the amount of acceptable overload that the user should determine according to the upstream fuse amp and downstream consumption.
t1c	Overload cutoff operation time	0.1 … 30 seconds	3	It refers to the time when the protector cuts off after the occurrence of overload, which should be set between 1 and 3 seconds considering the starting current of the equipment.
t2c	Overload connection delay time	1 … 500 seconds	60	It refers to the time that after overload occurs, the protector allows reconnection, which should be set above 1 minute.
cF	Define the number of overload reconnection times	1…20 bar/off	3	When an overload occurs, after the defined period of time, the protector connects again. When multiple overloads occur, by defining this parameter, the protector is prevented from connecting too much.
Uc	Voltage calibration	-9.5 … +9.5 percent	%	This parameter needs to be changed when the voltage display shows a higher or lower value than the actual value. By reducing or increasing the percentage, the actual voltage can be reached with high accuracy.
Cc	Current calibration	-9.5 … +9.5 percent	%	This parameter needs to be changed when the current display shows a higher or lower value than the actual value, and by reducing or increasing the percentage, the actual current can be reached with high accuracy.

Tips for installing a single-phase current voltage protector

1- It is recommended to use an expert for installation and settings

2- It is recommended to use an original miniature fuse and current leakage protector before the protector.

3- According to the above figure, the input phase should be connected to L and the input neutral to N, and in the same way, the output neutral should be connected to the null ingot and the output phase should be connected to the input of the miniature fuses.

4- To connect the wire to the device, be sure to use the appropriate wire head

5- Make sure the connections are tight because loose connections cause heat and fire.

6- It is recommended to check the correctness of the output relay once a year by Shasti Power by disconnecting and connecting it once.
