Product 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)
Top & bottom shielding covers are designed for safety and fashion out looking, also easy for wiring installation
In case of 0.5 Hz sudden power losses, system output can be switched off immediately. Once the power is restored, the system will buffer the output to prevent the voltage surge for fuse burn-down
Main power is one spec. Design for 200~480VAC
Automatic power frequency detection for 50~60 Hz. 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, 0~5 VDC, 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.
Installation and ambient conditions
When the power regulator is operating, the heat will be generated automatically. Please install the system vertically and leave some empty space on two sides to avoid the temperature inside the regulator rising continuously
There must be some ventilation holes on the control box. Please follow the principle of hard air rising to install the ventilation holes or extra cooling fans
Please avoid installing the regulator in the place with high temperature or poor ventilation. Otherwise, the maximum operating capacity must be set lower than 70% of the nominal capacity
Avoid installing the regulator in the places with heavy water evaporation, acid, alkaline, or corrosive air
Ambient humidity: below 90%RH (no condensation)
Ambient temperature: -10°C~45°C
Control and applied loading
Phase angle control : continuous phase angle control, steady output, current gauge reading remains steady. But, every half wave will produce harmonic wave.
Applicable loading : fixed resistance loading, variable resistance loading, inductive loading, IR light bulb
Zero crossing control : distributed zero crossing control, minimum resolution 1 Hz, no harmonic wave, and current gauge reading oscillates
Applicable loading : fixed resistance loading
Wiring and setup notices
Single phase Two-wire three-phase Three-wire three-phase
NFB → can cut off power to prevent personnel from electric shock during maintenance.
MC → can cut off supplied loading power when the power regulator malfunctions or the temperature is higher than the pre-set value. Cutting off the power can avoid the system burn down by overheating and prevent more serious damage.
Power regulato → can adjust the output power according to the control signal. (This product is embedded with the high-speed fuse, extra fuse is not necessary.)
Standard main circuit setup: main power →molded case circuit breaker → contactors → power regulator → loading
The screw must be tightened during the wiring setup to avoid high temperature resulting from bad contact
Once the wiring setup is completed, the front panel and safety cover must be properly installed before the system is powered up to avoid the electric shock or short circuit caused by dropped conductive objects.
