INDUSTRIAL Grade AVR, Servo Motor Type (3 Phase 10~300KVA)

Simple & Reliable AVR You can Trust!

► +25 % / -30 % WIDE INPUT VOLTAGE RANGE

±15 % as standard. ±20 %, ±25 %, ±30 %, ±40 % or others are available on request.

► ±1% ~ ±2% PRECISE & LINEAR VOLTAGE REGULATION RATE

Output Voltage Accuracy can be stabilized within a safety working range, even in high voltage fluctuation areas.

► ADJUSTABLE OUTPUT VOLTAGE ACCURACY

±1 % ~ ±5 % Output voltage accuracy is adjustable

► BETTER THAN 98 % VA EFFICIENCY, FROM 0 TO 100 % LOAD

Very low losses and minimal heat dissipation.

► HIGHER LEVEL OF SURGE AND LIGHTNING PROTECTION

Special design to deal with high level protection for Telecommunication applications and for equipment that require a higher level of Surge, Spike & Noise Protection.

► REVOLUTIONARY VARIAC / SLIDAC AND CARBON BRUSH

Improve its inherent weakness in order to prolong the service life of AVR.
For further introduction, please refer to the Chapter of "MAIN STRUCTURE & KEY COMPONENTS"

► INDEPENDENT PHASE CONTROL (3PHASE UNITS)

Independent voltage regulation. Every phase remains ±2 % output voltage when AC power encounters 30 % phase unbalanced, non-linear loads or heavy loads.

► STRONG OVERLOAD CAPABILITY

Sustained 200 % of its rated loading capacity, no voltage goes down extremely.

► SOFT START LOAD PROTECTION

Ensure the output voltage starts up from the lowest voltage when it commences full stabilization.

► FULL PROTECTION

Input Circuit Breaker, Magnetic Contactor for abnormal protection of :

• Over Voltage Protection:
If Input voltage exceeds voltage regulation range, the AVR will cut off output voltage automatically and shield abnormal voltage enters into the AVR directly or burn circuit boards.

• Under Voltage Protection:
When Input voltage is too low, it will cause malfunctions of machinery automation; Product failure rate will increase as well.

• Phase Failure Protection:
Should one of the electric wires is disconnected abruptly while AVR is working, the AVR will cut off at once and Red light indicator is flashing. Verify if the connected equipment remains in Safety Electrical mode and prevent the load from serious damage.

• Time Delay-off & Soft Start Protection: Instantaneous power blackouts and recovery will damage electrical loads.
While AC power recovery, the AVR starts automatically from low voltage output, to ensure the security of load

► MANUAL MAINTENANCE BYPASS SWITCH

The switch is for periodically maintenance and service. Not affect machinery running in any ways.

► CONCEALED NON-FUSE CIRCUIT BREAKER

Prevent man-made damage or careless machine shutdown. Fitted with Overload protection.

► SAFETY HIDING-STYLE SWITCH SHIELD

Prevent damage or man-made wrong action during transportation which would cause no voltage output.

► COMPLIANCE WITH INTERNATIONAL STANDARDS

Electro-Magnetic Compatibility (EMC) Directive: IEC61000-4-2 / 3 / 4 / 5 / 6 / 8 / 11,
Low Voltage Directive (Safety): EN61000-6-2 / 4

► CE CONFORMITY

European Union Directives 2004/108/EC (The EMC Directive) and
2006/95/EC (The Low Voltage Directive)
