Intelligent Multi-function Current Protector Voltage Protection device stabilizers


I. Purpose

   Intelligent multi-function current protector is a comprehensive intelligent protector integrating severalfunctions including electric energy measuring, overcurrent protection, over-/under-voltage protection, resistance(malignant load) protection and leakage protection. In case over-current, over-/under-voltage, or leakage fault occurs in the circuit, the protector can instantaneously cut off the power and protect the electrical equipment fromburning-out. When all lines return to normal state, the protector can automatically restore power. The parameters of this protector, such as over-current value, over-/under-voltage value, leakage current value, resistance(malignant load) current value, actuation time and recovery time, etc., can be setting as needed. It still possessesthe function of fault memory and inquiry as well as factory data reset. The real-time voltage value and current value and electric energy value are displayed cyclically. Each time you press the button"", the voltage, current and electric energy to be displayed separately while you press the button"", all the alternatives can be display. Itis so flexible that it can be used as a voltmeter, ammeter or coulombmeter. Users can choose the appropriate type of protector according to the actual situation.

 VI.Normal service conditions and installation environment

  1. The ambient air temperature shall not exceed +40℃ to -5℃, and the 24-hour average shall not exceed +35℃.

  2. The relative humidity of the air at the installation position shall not exceed 50% when the ambient airtemperature is +40℃, Higher relative humidity can be obtained at a lower temperature, for example: When theaverage minimum temperature of the month with the highest humidity is +20℃, the average maximum relative humidity of the month will reach 90%. Appropriate measures should be taken to prevent the condensation due totemperature change.

  3. The altitude of the installation position shall not exceed 2,000m.

  4. The protector shall be installed in the medium free from explosion hazard and gas or conductive dust that areable to corrode metals and destroy the insulation.

  5. The protector shall be installed in the position where there is no rain or snow.

VII. Announcements

  1. When carrying out various operations or tests, you shall follow the relevant procedures and focus on thefollowing items to ensure proper and safe use.

  2. Wire the input and output ends properly according to the product identification.

  3. Line conductors shall meet the relevant current standard values, and the load current shall not exceed the maximum protection current values of the protector.

  4. The neutral line N shall be connected properly and securely. The zero line N of the protector shall be directlyconnected, and it has no disconnection function.

  5. Check the wiring carefully before powering on.

  6. After the product is powered on, do not touch the live parts to avoid electric shock accidents.

  7. This protector has no short-circuit protection function and it shall work with miniature circuit breaker. If the miniature circuit breaker is not used for protection, the short circuit current will not be broken when there is a short circuit fault at the input or output ends of the protector.

  8. The protector has self-resetting function. After the overcurrent protector performs protection anddisconnection, the load appliance shall be removed immediately, and the circuit line shall be checked. Otherwise, the protector will frequently switch on the load appliance, which will eventually damage the electrical applianceand the protector body.

  9. The protector has no isolation function. It shall work with the miniature circuit breaker, and break off theformer circuit breaker switch when repairing the circuit line.

  10. Notice! When the breaking time of under-voltage exceeds 0.2 seconds, the protector will not open afterthe power fault. (MCU will not work with power lossing after 0.2 seconds of power fault)
