INTRODUCTION

2.1 General

Wise33 / Wise MP33 series AVR, a 3-phase automatic voltage regulator or stabilizer, is compatible with
both star and delta circuit connections. With 8/16 bit microprocessor controlled, Wise33 / Wise MP33 series
AVR supplies pure sine wave output with low harmonic distortion at high accuracy and efficiency. Wise33 /
Wise MP33 series AVR comes with built-in surge protector and audible alarm to alarm when the AVR has
faults. Furthermore, it has LED display and LCD screen to display operating status and electrical data.

Normal operation mode: Wise33 / Wise MP33 series AVR takes power from main electricity supply.
Then, the current flows to automatic voltage regulator (AVR) circuit to regulate the voltage level. If the
voltage is too high or too low, the AVR circuit will regulate it to the level that is safe for the loads. Then, flows
to EMI/RFI noise filter circuit and check load level at Power watcher to protect overload. If the AVR is
overloaded, it will alarm. You have to disconnect some loads. If the AVR is under these situations; output
over/under voltage, overload, input frequency fault, over temperature, and etc., it will shut itself down and
restart automatically when it returns to normal (for autotomatic restart mode only).

Maintenance bypass mode: When the Maintenance bypass switch is ON, the loads are taking power
directly from main electricity supply. To stop the AVR and disconnect it from main electricity supply for
maintenance, turn off the input breaker.

Note: There are 2 restart modes (automatic and manual restart). After the AVR shuts down and the restart

mode is manual, once it detects no more faults, it will alarm. You can restart the AVR by pressing

simultaneously once.
