JKL1E SERIES INTELLIGENT AUTOMATIC COMPENSATION CONTROLLER FOR WATTLESS
POWER |
 |
1.BRIEF INTRODUCTION
The JKL1E series automatic compensation controllers for wattless power are for the special
control use for the computers in low-voltage distribution system to compensate wattless
power. The series include four models, 4-、6-、8-、10-channel which can be used as
supporting units for various low-voltage electrostatic capacitor banks respectively.With
the most advanced technologies in the world adopted in its production, |
the unit is not only compact in size,
light in weight, but enjoys a pleasant appearance and two interior and exterior covers
that are all made of intensified fire-resistance plastics. Complete functions, strong
anti-interference, always-stable operation and accurate compensation, are the four main
distinguished features of the products.
All performance indices of the products have been proved to reach or
exceed concerning ZKB44001-89 national standards by passing two major national performance
tests, one conducted by the Chinese Computer-controlled Power Distribution Equipment
Testing Center (Cert. No. 90DY089) and one by the Guangdong Provincial Electric Power
Testing Institute. Besides, the products are also awarded production license by the
National Ministry of Machinery and Electronic Industry (No. K11) and certificate of
conformity for ISO9002 international quality system. |

2.FUNCTIONS & FEATURES
- Network power factors are displayed in LED digits: lagging (0.00-0.99)，leading (0.00-0.99)
- The digital display of the preset values of Cosφ，delay
time，over-voltage can be finished by operating the three
function keys on the panel keyboard. Besides, concise man-machine talk style makes it far
more convenient for operation. All parameters are easily set and remembered and protected
even in power-off situation.
- When the network voltage exceeds the preset over-voltage value for the unit， the digital display is automatically changed from Cosφ to the real-time voltage value of the network. Meanwhile，formerly closed capacitor banks are cut off, automatically,
quickly and level by level, accompanied by output signals initiated by over-voltage
contacts.
- It can distinguish current polarity by sampling (automatically distinguish the polarity
of current) and automatically switch polarity. This function brings much convenience for
installation, debugging and operation.
- When the sampling signal circuit is open or there is no sampling current signal input，the Cosφ meter automatically
displays “O.CC”
- The output actions take the circular operating mode of the first to close, the first to
open and vice versa. There is the 1-2-2-2-2-1 code operation mode specially designed to
meet the operation requirements of the on-spot compensation devices.
- Anto/Manual switchable. When switched to Anto mode，the unit
automatically tracks the power factor and the wattless current of the network and controls
the automatically closing and opening of capacitor banks. In manual mode，the same functions are manually performed.
- There are LED indicators for leading, lagging, over-voltage as well as the input of
program
- The strong anti-interference feature of the unit can withstand the interferential pulse
of up to 2000 volt directly from the network. This function exceeds concerning national
standards.
