Product Description
NCX-320K/400K/500K/600KVA 3Phase, Electronic/IGBT/SCR/Thyristor, Heavy Duty Automatic AC. Voltage Stabilizer
Product Features:
NCX series Electronic/SCR/Thyristor, Heavy Duty Voltage Regulator consists of compensation circuit, voltage regulating circuit, control circuit, input sampling circuit, output sampling circuit, output control circuit, protection circuit and bypass circuit. It has a simple structure which as no motor, chain, and gear transmission system. Its mechanical fault is zero, so it is maintenance-free for a long time. The main circuit which adopts multiple compensation transformer combination ,can achieve stable voltage by contactless switch of thyristor and completely avoid the maintenance of brush wear as well as high frequency interference caused by brush contact spark. Therefore, it has long service life and more than 100, 000MTBF hours. The product is stable due to its all power supply protection function, it can reach more than 98%. Our product has 1 to 100KVA single phase, 3 to 2000KVA three phase, less than 100ms response time and ±2% to ±3% precision. Its compensation range is often ±20% and we can design ±30%, ±40% and ±50% compensation, and it has following features:
1). Adopting the advanced duplex winding compensation technology which ensure little waveform distortion.
2). Adopting one-chip computer to control the thyristor and shifting combination for timing compensation adjustment enable it to realize the fast non-contact
adjustment. Strong instantaneous overload capacity makes it available with various loads.
3). Adopting one-chip computer split-phase control, it has the functions of delay starting-up, three-phase automatic balance addition adjustment, display, alarm and protection of open-phase, overrun and malfunction etc.
Main Functions:
1). Power on mode: Voltage regulator is provided with automatic power on and manual power on for users to choose;
2). Over and under voltage protection: When the output line voltage exceed 415V or below 345V(output phase voltage below 200V or exceed 240V) several seconds delay, the machine automatic turn into " By Pass" mode at the mean time, the value of input voltage equals to the output voltage, Buzzer alarm continuously and the yellow indicator is illuminated;
3). Fault protection: When the regulator component generates failure, regulator will automatically switch to bypass or cut off the output and send out sound and light alarm. The value of input voltage equals to the output voltage. Buzzer alarm continuously and the yellow indicator is illuminated;
4). Phase loss and phase sequence protection: When the three-phase output power produces phase-lack or fault phase, regulator will automatically cut off the output voltage;
5). Short circuit protection: When the regulator has short circuit problem in the output end, the circuit breaker will automatically cut off the power input;
6). Manual bypass: The regulator can be manually turned bypass operation;
7). Alarm and silencing function: When it is in protection state, regulator can send out audible and visual alarm and has alarm and silencing switch or selection;
8). Lighting surge protection: When it is in protection state, regulator can send out audible and visual alarm and has alarm and silencing switch or selection;
9). Remote monitoring(optional): It can be quipped with remote monitoring system in order to monitor operation of voltage stabilizer.
10).Power supply filter(optional): In the voltage regulator circuit, it can be equipped with filter.
Application Scope:
It's widely used in Broadcast & Television system, Microwave telecommunication unattended station, Industrial control system, Computer system, Industrial equipment supporting, Elevator supporting etc. occasions that requires regulated power source.
