dynamic low voltage power factor improvement panel 

I Type: WDBP

II Application

dynamic low voltage power factor improvement panel adopts the thyristor/SCR as the switch. It can improve the power factor, has good energy saving effect, can prevent the amplification of the harmonic.

III. Advantages

• Has the function of zero-cross switch, avoid the harmonic from the non-linear parts
• Long life span, especially in the occasion where the load and power factor change fast, the life span is much longer than compensator with contactor.  
• Fast response within 10ms
• No contact switching, can be used in places with dust.
• No contact point switch, suitable for dusty places.
• With many protections, such as over voltage, over current, under voltage etc.
• Small maintanance work
• Many protections: over voltage, over current, under voltage etc.
• No inrush current, can be used in frequently switch occasion
• Equipped with reactive power compensation controller, it is automatic cycle, switch capacitor with steps, the switch time interval can be adjustable, make the reactive power consumption to be the lowest, then improve the quality of electric network, reduce the consumption of distribution system and transformer
• A suitable capacity can increase the power factor to more than 0.92
• The heat elimination slot on the bottom of the cabinet can make the device cooling immediately.
• The top cover of the cabinet body can be removed if necessary, it is convenient for installation and maintenance.
• The panel of the cabinet is spray craft, which make the product has a good touch feel
• Protection is IP 30, also can be changed from IP20 to IP 40

IV Working conditions

• 1. Indoor using, with good ventilation
• 2. Indoor installation, altitude is less than 1000m, no harmful gas and dust, no explosive dust
• 3. Long time over voltage is not more than 1.1Un, long time over current is not more than1.35Un.
• 4. Ambient temperature is less than 40 degree centigrade, when capacitor switch, the lower limit of temperature is minus 40 degree centigrade
• 5. Humidity: less than 50% when it is 40 degree centigrade
