primary circuit and two control systems and each control system
serves as the backup for the other so as to guarantee the
reliability of the device; ★ Optional manual or automatic mode; ★
Load connecting method: Y0 or △ mode; ★ Temperature control
accuracy: ≤1℃; ★ Real-time temperature detecting and on-line
temperature value setting; ★ PID calculation with on-line adjustable
parameters; ★ Fault monitoring such as quick fuse breaking,
over-current, temperature overrun of wind machine and heating
devices and pulse phase-loss; ★ Optional constant - temperature
operation and constant power operation mode; ★ Zero-crossing
triggering of controllable silicon by constant interval (KTF is set
to be periodical mode); ★ Monitoring various kinds of faults and
warning by sound, light and digital display by computer; ★ Remote
data communication system is optional in KTF power controller \ to
connect computer system and so as to implement remote monitoring and
remote setting. II、ORDER INFORMATION ◎、The following parameters are
required: Model, wiring method and quantity of capacity sensor and
thermal sensor
II. Technical Indexes
|
The rated output voltage |
Three-phase 3×220V, 3×440V（the user can set it himself） |
|
Three-phase 3×380V |
|
|
Fluctuation range of the output voltage |
More or less than 10% of the rated output voltage |
|
Frequency |
50Hz or 60Hz |
|
Power of air blower |
AC220V 15-65VA |
|
Output voltage scope |
0-98% of the rated voltage |
|
Input current scope |
0-105% of the rated current |
|
Output control signal |
DC 4-20mA |
|
Applicable load |
Resistive load, inductive load, transformer primary side and gas discharge load |
|
Start and turn-off mode |
Soft start, soft turn-off, time: 2 to 3 seconds |
|
Structural mode |
Unit type below 500A, cabinet type above 500A |
|
Constant current features |
When adopting the current feedback and the control signal is invariant, though the load changes, the output current can be stable at any value within the scope of the rated current without change. |
|
Current-limiting features |
When the output working current is more than 105% of the rated current, the conduction angle will be reduced automatically. |
|
Over current protection features |
When the output working current peak is more than 105% of the rated current, the power controller cut off the output in half cycle, and conduct self-hold. If the over current indicator light is lit, there is touch output. |
|
Phase-default protection features |
When the output voltage lacks phase, the power controller will cut off the output, and conduct self-hold. If the phase-default indicator light is lit, there is touch output. |
|
Over-heating protection features |
When the air blower stops or the temperature of the radiator exceeds 80℃, cut off the output, and there is no power touch alarm output. |
|
Cooling type |
Natural cooling, forced air cooling |
|
Dielectric resistance |
Above 20MΩ（2500V megger）. |
|
Dielectric voltage withstand |
AC2500V, no flashover and breakdown phenomena in one minute. |
|
Relative humidity |
At 20℃, the relative humidity is 90%, without moisture condensation |
|
Anti-jamming capacity |
The main circuit can bear 10KV/3us impulse wave test. |
|
Working mode |
Continuous system |
|
Storage temperature |
-5～60℃ |
|
Working temperature |
-5～40℃ |
|
Altitude |
If it is less than 1000m, the rated value is invariant. If it is more than 1000m, the rated value will reduce 5% per 100m |
