Intelligent High Power Automatic Voltage Regulator
Compliance with international standard : ISO9001, IEC439, BS6527, IEEE587 standard
CE Conformity : EN55022, EN50082-2, ENV50140-1

APPLICATION :

Suitable for various kind of industry equipment, TV & Radio Broadcasting stations, Medical equipment, Turnkey plant electric power system, Building-Engineering equipment, Refrigerated-A/C equipment, UPS, Military equipment, Mining equipment, Electric-Machinery equipment, Large production line, Large electrothermal equipment, Large electroplate equipment, etc.

High Accuracy Intelligently Humanized - POWEREX High Power AVR

Intelligent Logic Regulation:
The powerful PSN AVR's series available adjust the regulating speed and regulation range according to the power's variation and the load character on the spot by a precise and unique motor to gain the most heavy-duty and satisfactory power regulation required.
Innovative panel design:
PSN AVR's display panel provides user a clear viewing which also may seen on the indicators' color to realize normal or abnormal. The green LED stands for normal, the red LED with buzzer shown abnormal.
Hi-power M.O.V. device:
Installed with hi-power M.O.V. for each phase, meet international standard IEEE587.
Separate regulator design:
PSN AVR is a three phase individual regulation design.When input voltage and three phase load unbalanced, PSN still maintain with accurate and balance output.
SOVP device:
Whether it is switch on or recover from power outage, the Start Over Voltage Protection will always re-start from low voltage.
Three phase quick fuse device:
In case of output overload or short circuit, the quick fuse will blown up, the AVR might force to low output voltage, and the display panel shown and warning.
Electronic bypass design for each phase and each section:
Each phase and each section available separate with their own bypass switch, even under bypass condition which still keep the over/under voltage and phase loss warning function.
Regulation is accurate and won't oscillate:
PSN's design is good to detect and adjust three phase individually, the high accurate regulation, output voltage won't oscillation.
Self-detect function:
Each time during the unit turn on the AVR, fast detect utility and itself whether under protect setting quickly, then supply precise voltage to the equipment.
Logic Assemble Function Programming:
Adopt with multilayer and big range DIP SW. logic assemble design, include high/low voltage, phase failure, delay setting, 3 phase instant regulation FUZZY range setting and 3 phase O/P regulation accuracy setting. All settings can operate and select easier, user can pre-set the most appropriate and precise adjustment in accordance with the load requirement.
Monitor / feedback / buzzer / dry contact:
Output voltmeter monitor three phase voltage. With individual three phase feedback buzzer, mute switch and remote monitor dry contact.
Series connection & parallel design:
Internal main parts with gang and parallel design, share the current and risk. With high reliability and long MTBF (from 1000KVA).
