Selective power limit protector JGXZ-63

1、Introduction

JGXZ-63 is a selective power limit protector, mainly used to limit the power consumption of individual electrical appliances with excessive power, and an intelligent power limit protector for exceeding the total power limit. At the same time, the product has multiple protection functions such as overvoltage, undervoltage, short circuit, leakage, temperature, frequency, and electricity measurement. The product has the advantages of modularity, intelligence, visualization, and supports the standard Modbus 485 communication protocol. All protection parameters such as overvoltage, undervoltage, power limit, leakage protection, etc. can be set according to the power demand to ensure that the protector can instantly cut off the power supply in case of overvoltage, undervoltage, short circuit, leakage and other faults in the line, protecting the electrical equipment from damage.

This series of products has a compact structure, beautiful appearance, and standard guide rail installation. It is mainly suitable for school dormitories, rental houses, and other occasions.

2、Product working principle

Example: Product default parameters: Single power is 0.2kw, limited to 3 times, total power is 2.0kw

a、 Connect 10 appliances with a power of less than 0.2kw separately, and at this time, the individual power does not exceed 0.2kw, and the total power does not exceed 2.0kw. The protector is working normally. If the single power of the connected electrical appliances does not exceed, but the total power exceeds 2.0kw due to too many connections, the protector will disconnect within the specified time, and manual reset is required at this time.

b、 When a single electrical appliance is connected with a power greater than 0.2kw, the red light P of the product flashes, indicating that an appliance with excessive power has been connected. If the load power supply is not disconnected and cut off in a timely manner within the specified time, the product will enter a countdown. When the countdown ends, the product will automatically close. If there are still over limit appliances after closing, the product will automatically disconnect. After exceeding the limit for more than 3 times, the reset button must be manually pressed to close the circuit.

c、 If the power of a single appliance does not exceed the limit, but exceeds the total power, the product must be manually reset to close after protection.

When manually pressing the reset button is required, all over limit electrical appliances need to be removed

3、Working conditions and parameters

3.1. The first normal power on will automatically close after a 1-second delay; The product will automatically disconnect within 1 second in the event of overvoltage, undervoltage, overcurrent, or leakage during the first power on;

3.2. Current protection parameters:

a. ≥ 1.0 times current, set range 1-120 seconds, default 10 seconds

b. ≥ 1.2 times the short-circuit current, 0.1 seconds to open the circuit

3.3. The ambient temperature should not exceed+40 ℃, not be lower than -5 ℃, and the average temperature over 24 hours should not exceed+35 ℃; At+40 ℃, the surrounding air humidity should not exceed 50%.

3.4. The sea level of the installation location shall not exceed 2000 meters.5. Pollution level III.6. There are no explosive hazardous media, no corrosive or insulating gases, and no conductive dust in the installation environment. There are also no areas affected by rain or snow.
