MAIN FEATURES:

 3 Digit LED Display

 Powerful Micro Processor based operation

Automatic CT Polarity Correction (K&L)

Automatic C/K adjustment

Gives Multiple Readings such as:

Power Factor, System Voltage, Required KVAR, Harmonic current over load, temperature inside PF Panel,

Alarm parameter and value

 Intelligent Alarm Functions:

Over-Voltage, Over Current (Harmonics)

Over-Temperature, Low PF Warning

 Individual Alarm programming & dis-enable

 Three operating modes: Auto, Man1, Man2 (Set at Auto Mode for regular operation)

Low voltage release : de-energises the output relays whenever mains failures exceeds for 20ms.

 High Voltage release : Switches off the capacitor banks in case of temporary phenomena connected with faults

or manoevres generating overvoltage with a higher frequency than mains.
