Powercom MAC – Macan — is a single-phase online double-conversion UPS designed to protect small and medium-sized IT systems, office equipment and telecommunications networks. The series is characterized by its compactness, the presence of an LCD display for status indication and a wide range of monitoring interfaces (USB, RS-232, optional SNMP). The system supports operation in stable conditions, ensuring high power quality and long battery life. Regular diagnostics allow you to detect malfunctions in time and maintain system stability.
What diagnostics include
Inspection / audit
- Visual inspection of the housing, display, terminals, connections and cables.
- Checking operating conditions: temperature, ventilation, location.
- Assessing correct connection to the network and load, checking grounding.
Electrical tests
- Measuring input voltage and frequency, checking compliance with the rating.
- Checking the stability of the output voltage, waveform and frequency.
- Testing the UPS response to the load and the speed of transition to battery mode.
- Checking for overloads and short circuits.
Inverter / bypass / charge
- Checking the inverter operation: waveform, stability, voltage.
- Testing the automatic bypass: correct switching and absence of delays.
- Analysis of the charger: operating mode, battery charge current and voltage.
- Viewing logs of events, accidents and failures.
Battery (battery system)
- Inspection of the battery compartment: condition of connections, presence of corrosion or damage.
- Measuring the voltage on each battery, checking the uniformity of the charge.
- Checking the autonomy time under test load.
- Evaluating the operability of the battery charge and discharge control system.
Cooling
- Checking the operation of the fans: RPM, noise, cooling efficiency.
- Temperature control of main power elements during operation.
- Inspection of ventilation holes, degree of contamination and possible blockages.
Communications / monitoring
- Checking the LCD display: correct display of parameters and warnings.
- Testing USB and RS-232 ports, checking connection to monitoring software.
- Checking the operation of the SNMP card (if available), integration with network monitoring systems.
Technical report
- Full report with test results: voltage, current, temperature, battery condition.
- Identified deviations, potential risks and maintenance recommendations.
- Recommendations for preventive measures and replacement of components if necessary.
When diagnostics are needed
- Regularly, at least once a year, to maintain stable UPS operation.
- After errors or unexpected transitions to bypass or battery mode.
- After prolonged downtime or storage of equipment without power.
- Before increasing the load or connecting additional batteries.
