Controller Sector).
PARTICULAR INFO
I、MAIN PERFORMANCE AND CHARACTERISTICS ★ Every device includes one
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
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
