6,Technical performance comparison

Type	3H-W Non-contactcom pensated AC stabilizer	3H compensated column AC stabilizer (servo mechanical type)	Induction type voltage stabilizer
Working principle	Adopting microcomputer to control the SCR module for quick switching, through transformer synchronous frequency, phase lock and sine wavestack compensation to keep output voltage stable.Fast response speed, no carbon brush, no contact, no machinery, no spark, three phase separation.	The output voltage of the secondary winding of the compensation transformer is stabilized by changing the movement of the carbon brush frame on the voltage regulator transformer. Carbon brush, touch point, mechanical transmission.	The relative voltage of input and output is changed by changing the phase angle of stator and rotor
Response time	Fast: the time from stable to rated voltage is no more than 40ms, which can inhibit the instantaneous input of high and low surge voltages and effectively protect precision equipment.	Slow (3~5s) Motor control (mechanical)	Slow (3~5s): it belongs to the hysteresis stable voltage, which cannot suppress the instantaneous input high and low surge voltage, and it is difficult to protect the precision equipment
Parameter setting	The buttons on the display panel can set various parameters.	cannot set	cannot set
Three phase unbalance	The conventional product is three-phase demodulation with three-phase voltage automatic balance function.	Conventional three - phase regulation, not with three - phase voltage automatic balance function.	The conventional three -phase modulation does not have three - phase voltage automatic balance function.

8,Ordering instructions
9.1 selection method. The voltage regulator is generally selected according to the following formula
S = PS ` / cosφ type: S - the actual needs of stabilizer capacity, P - load power, S ` - safety coefficient, cosφ- load power factor.
9.2 power factor and safety factor
9.2.1 pure resistivity load: power factor is 1 (such as resistance wire, electric furnace, etc.), and safety factor is 1.1argonium 1.5.
9.2.2 inductive load: the power factor is generally 0.6-0.8 (such as elevator, air conditioning and motor equipment), and the safety factor is 1.5-3.
9.2.3 capacitive load: the power factor is generally 0.6-0.8 (such as: microcomputer room, broadcast TV, etc.), and the safety factor is 1.5-2.
9.2.4 comprehensive load: power factor is generally 0.6-0.7 (for example, comprehensive load of factories, hotels and household appliances), safety factor is 1.5-2.5.
Safety factorselection principle reference: in the environment of inductive capacity load, the
starting current of load is large when selecting the type, which will cause impact on the voltage regulator. In order to ensure the safe operation of the product, the safety factor must be carefully selected when selecting the type.
