Three phase SCR power controller
Three phase SCR power controller CTH series. zero cross control and Phase angle controlMain power voltage: 200-480VAC Rated current: from 36A TO 230A.Rated power 7KW,11KW,17KW,22KW,28KW,33KW,39KW,44KW.Auxiliary power source: 220VACnput signal: 4~20mA,1~5VDC,2~10VDC,0~20mA,0~5VDC,0~10VDC,Buffering time: Buffering time 2 seconds Product Features:1.The SCR unit attached with high speed fuse in order to prevent the damage of SCR due to the shortage current (di/dt).2.The unit is packaged instruction with less dimension, easy for installation and wiring.3.The causes of malfunctions can be indicated by individual LED lamp, easy for trouble shooting.4.Less non-linearity output provides accurate control of temperature.5.High quality and high technical productions with no electrical interference. Operation Environment:1.Ambient temperature : -10~45 0C, Relativ humidity : Max 90% Installation:1.The SCR unit will produce heat itself during operation, please erect it upward according to the instruction.2.The panel must be upward ventilated for hot air. We recommend mounting a ventilating fan in the control panel.3.Do not install the unit in the space with high temperature and poor ventilating, Do not operate the unit exceed 70% of rated output in case of abovementioned poor ambient conditions. Load Test:1.The SCR unit will not well functioned in case of less output load (0.6 Amp).2.Please connect the load at least 0.6 Amp. Warning1.The panel must be upward ventilated for hot (fan in the control panel)2.Make choice of purchase please cogitate power fluctuant rate and heater error or order aggrandize a grade Other features: * Independent adjustment of Max and BIAS.
* Down-opened Panel, easy for fuse replacement.
* VR of Max and SFS are installed in the front panel, easy for adjustment.
* Multi-LED display panel makes the operating condition clear.
* The auxiliary powers(AC1,AC2) are independently controlled for all models.
* Build-in buffering output adjustment(SFS VR), adjusting range 1~22 seconds.(Only for the phase control product).
* Main power is one spec. Design for 200~480VAC.
* Automatic power frequency detection for 50~60Hz. No need for selection or switch.
* Automatic detection and display for power out of phase, SCR overheating, and fuse burn-down with one set of alarm dry contact output.
* In cases of SCR overheating or fuse burn-down, the system output is stopped immediately. Once the malfunction is eliminated and power is restored, the system will buffer the output to prevent the fuse burn-down.
* 4~20mA,1~5VDC,2~10VDC,0~20Ma,0~5VDC,0~10VDC, dry contact points, etc. and all control signals are ready to use.
* Triggering circuit and the main board are designed separately to avoid the main board damage when main circuit malfunctions.
* Using European detachable control signal connector for easy replacement without re-wiring installation.
* CE CERTIFICATION.
