cSMARTIII

Product catalog summary

Overview: The Computer SMART III is a sophisticated power factor regulator designed to optimize energy efficiency by using either one or three current transformers. It functions as both a power analyzer and a controller for residual leakage currents, offering enhanced preventive maintenance and safety features.

Key Features:

Measurement Flexibility: Supports both single and three transformer configurations, allowing adaptation to changes in energy penalties, consumption habits, and system imbalances.
Compatibility: Suitable for installations with up to four objective cos φ and medium voltage compensation units.
Technical Specifications: Operates on a power supply voltage of 100-520 Vac with a frequency of 50-60 Hz. It offers a measurement voltage range of 35-520 Vac Ph-Ph and 20-300 Vac Ph-N.
Accuracy: Voltage and current measurements have an accuracy of 0.5% ±1 digit, while active power measurement accuracy is 0.5% ±2 digits.
Environmental Conditions: Operates within a temperature range of -10 ºC to +55 ºC and a relative humidity of 5-95% without condensation.
Safety and Standards: Complies with IEC 62053-23, IEC 61326-1, EN 61010-1, and UL 508 standards, with an insulation category of III Class II.

Applications: Ideal for installations requiring flexible compensation needs across different time periods and for replacing regulators in capacitor banks.

Connections and Dimensions: Provides detailed connection options for various configurations, including three phases plus neutral with one or three current transformers.

Power Factor regulators Smart Power Factor regulator Description Measurement with three current transformers guarantees an analogue reading of the company meter. The Computer SMART III reactive energy regulator is the only regulator on the market that offers the possibility of using 3 measurement transformers in addition to the conventional method of measuring with a single current transformer, as well as providing the functions of an integral power analyzer and controlling residual leakage currents. Computer SMART III is a regulator that ensures excellent preventive maintenance by means of programming its alarms and the options for testing the capacitor status, offering maximum supervision and safety of your compensation unit. Application The connection of 1 or 3 transformers makes computer SMART III the perfect regulator in any installation, allowing the following: —— Changing from 1 to 3 transformers in the following cases: –– Changes in reactive energy penalties –– Changes in consumption habits –– Significant imbalances in the system —— Replacing the regulator of any capacitor bank —— Perfect for installations with up to 4 objective cos φ, since it can —— adapt to any compensation need (different time periods). —— It can be used with Medium Voltage compensation units.
