HENGYI ELECTRIC GROUP CQC by China Quality Cer�fica�on Center | Chinese na�onal patent product JKGHYBA580 Intelligent Combina�on Low voltage Reac�ve Power Measuring & Control Device 1 General The JKGHYBA580 series reac�ve compensa�on measuring device is a new type low-voltage reac�ve-load compensa�on controller that integrates measurement, control and display. In comparison with the conven�onal low-voltage reac�ve-load compensa�on controller on the market, it mainly integrates the common voltmeter, ammeter, power factor meter, reac�ve power meter and ac�ve power meter into one controller. It can further display the three phase compensa�ng current and the capacitance switching state. The product uses the RS485 communica�on system and can connect at most 32 HY series combined type low-voltage electric capacitors of the company by networking. 2 Types and meanings JKG HY BA 580(I) Specifica�ons Auto-control Enterprise code Controller type Note：JKGHYBA580（I）is exclusive for intelligent combina�on harmonic restraining low voltage power capacitor compensa�on installa�on. 3 Normal working and installa�on condi�ons 3.1 Ambient temperature：-25℃ ~ +55℃ 3.2 Rela�ve humidity：40℃ ≤20%；20℃ ≤90% 3.3 Al�tude：≤2000m 3.4 Environmental condi�ons: no noxious gas and vapour; no conduc�vity or explosive dust; no violent mechnical vibra�on. 4 Main parameters and other condi�ons 4.1 Measurement error Voltage：≤±0.5%，Current：≤±0.5%， Ac�ve power：≤±1%，Reac�ve power：≤±2%，Power factor：≤±1%。 4.2 Control accuracy Power factor：≤±1%，Reac�ve power：≤Minimum capacitance ±120%。 4.3 Control capacity JKGHY580 Can control 20 sets of capacitors，JKGHY581 Can control 32 sets of capacitors。 4.4 Mains condi�ons Rated voltage：AC220V±20%；Voltage distor�on rate≤5%；Rated frequency：50Hz； 5 Features 5.1 It uses a special electrical energy measurement chip so as to make the measurement parameter become more accurate and the control efficiency become higher. 5.2 It displays more contents. The device can display the three phase voltage, three phase current, three phase power factor, bonded phase power factor, three phase ac�ve power, three phase reac�ve power and three phase compensa�ng current. It can further display the capacitor switching state. 5.3 The equipment has a friendly human-computer interface that can make it convenient for the user to inquire the parameters such as voltage, current, power factor, ac�ve/reac�ve power compensa�ng current etc. The user can change and set the parameters such as overvoltage value, over-temperature value, capacity, �me delay, transforma�on ra�o, upper and lower limits of the power factor etc. 5.4 It uses an an�-interference single-chip and the double watchdog technology. It further uses the count vo�ng and me
