Adjustable High Voltage Low Voltage Surge Protection 2pieces

High voltage / Low voltage monitoring device. It can be use for Air conditioner, pumps , and can be use to protect a room apartment / small apartment, shop or an office , it can be used with contactor for big apartment / shop where you have more than 1 AC it can  be connected with a breaker. It monitors voltage to make sure that higher or lower voltage/ current that is not within your set range does not flow or supply . it has delay time of 1 - 500seconds adjus table, it depends on the stability of your supply voltage that will determine delay time before supply and you can also set your desire delay time.This device ensure that your equipment is always protected . Model Number 63ampsPhase Single PhaseUsage/Application Weight 200gVoltage Protection Range 0-450V For 63A, 0-600V For 20A/40A.Impulse Withstand Voltage 4kVApplication
Over Voltage And Under Voltage Protective Device With Auto-Reclosing Function (OUPA) is an intelligent protector integrated with overvoltage protector, under voltage protector and over-current protector. In case of over-voltage fault, under-voltage fault or over-current fault in line, this product can instantly power off to prevent electrical equipment from being burnt. The over-voltage, under-voltage  values of this product can all be set up by yourself and can be adjusted on the basis of local practical condition.Product features In case of over-voltage fault, under-voltage fault or fault in single phase line, the product can power off the line and can automatically restore connecting the line over a time delay after voltage of the line is recovered to normal condition.In case of transient over voltage in line, the product can protect your equipment.

In case of over-voltage fault, under-voltage fault or over-current fault in line, this product can instantly power off to prevent electrical equipment from being burnt. The over-voltage, under-voltage and over-current values of this product can all be set up by yourself and can be adjusted on the basis of local practical condition.Product features In case of over-voltage fault, under-voltage fault or over-current fault in single phase line, the product can power off the line and can automatically restore connecting the line over a time delay after voltage of the line is recovered to normal condition.In case of transient over voltage in line, the product can protect the equipment from false operation.In case that the line subjects to unstable voltage or sudden power-off and power-on due to loosened connection and other fault, the product will disconnect the line.When fault voltage of the line reaches the peak, the product itself will not be damaged.Voltage protection range: 0—450V for 40A 0—600V for 20A/40A.Impulse withstand voltage: 4KV (in compliance with safety standard for electrical appliance of category III).Main technical parametersRated voltage: 230V;Frequency: 50Hz/60HZRated current: 63A Under-voltage action switch-off value: 210V-145V (adjustable) (default: 170V)Over-voltage action switch-off value: 230V-300V (adjustable) (default: 270)Reconnect time (delay on time): 1s-500s (default: 30s)Cut off in 1s if over volatge, under voltage or over current.Power consumption=2WElectrical and mechanical life=100000 cycles
*SETTING*Hold setting for 3sec first parameter is over voltage set between 221- 300 using the arrow2) press setting over voltage recovery value set between 221-2993) press setting over voltage actuation time set between 0.1 - 10sec4) press setting under voltage value set between 151 - 2205) under voltage recovery value set between 151 - 2196) under Voltage protection actuation time must not be more than 0.3sec7) press setting delay time for fault recovery set between 2 - 512 sec8) press setting power ON delay time set between 2-512sec9) press setting set AU not AH for all your setting to be automatic10) press setting it display *I UL * it is to inquire the last fault that occur on your supply its either UL or UH under or over voltage 11) finally press setting to activate your modifications. It will display END
Note that the factory setting is OK to protect your equipment but if need requires to modify the factory setting then you must follow the steps to the end if not your modifications won't be activated. To go back to factory setting press the two arrows together for 3sec .
Read manual for more clarification.Thanks.



WARNING ENSURE THAT YOU DO NOT OVERLOAD THE DEVICE WHEN YOU ARE NOT USING WITH CONTACTOR. it is best used directly with individual sensitive device you want to protect, for multiple devices that takes more than 10amps each, use one for each of the item or use with contactor.
