Powercom VGSL – Vanguard II — is a series of single-phase online double-conversion UPS (VFI) designed to protect critical equipment in IT infrastructure, automated control systems, telecommunications and industry. Models in this series support precise regulation of power parameters, have advanced monitoring tools (LCD display, USB, RS-232, SNMP), and are capable of operating with a wide range of voltage and frequency. Regular diagnostics allow you to maintain high reliability, timely detect deviations in the system and extend the service life of the batteries.
What diagnostics include
Inspection / audit
- Visual inspection of the integrity of the housing, display, terminals and cables.
- Assessment of operating conditions: temperature regime, ventilation, dustiness.
- Checking the correctness of the connection to the network, load and grounding.
Electrical tests
- Measurement of input voltage and frequency, checking compliance with the declared parameters.
- Analysis of output voltage, frequency stability, quality of the sinusoidal signal.
- Testing the operation of the UPS under load, including response to voltage surges.
- Check for overloads, system response to emergency conditions.
Inverter / bypass / charge
- Evaluation of inverter operation: voltage, frequency, harmonic level.
- Checking the functionality of the static bypass: correct switching, delays.
- Testing the charger: output current, charge mode, stability.
- Analysis of events and failures in the device event log.
Battery (battery system)
- Visual inspection of the battery compartment: contacts, condition of the housings, presence of corrosion.
- Measurement of voltage on each battery, identification of weak elements.
- Testing autonomous operation under load.
- Analysis of charge and discharge efficiency, control of the balance between batteries.
Cooling
- Checking fan operation: noise, speed, cooling efficiency.
- Evaluating the temperature of the inverter, charging module, power cells.
- Checking the cleanliness of air ducts, checking the condition of filters (if available).
Communications / monitoring
- Testing the operation of the LCD display: relevance of displays, access to parameters and logs.
- Checking USB, RS-232, SNMP interfaces: data reading, communication stability.
- Integration with monitoring software or SCADA systems, checking event transmission.
Technical report
- Generating a report with all measured electrical parameters and component statuses.
- Identified deviations, risks, current or potential malfunctions.
- Recommendations for eliminating defects and scheduled maintenance.
When diagnostics are required
- At least once a year for scheduled control and prevention.
- After an emergency bypass or unexpected power outage.
- After replacing the battery or a significant increase in load.
- After installing, moving or storing the equipment for a long time.
