Powercom SNT – Sentinel — is a series of single-phase online double-conversion UPSs designed to protect critical systems in office, IT, telecommunications and industrial environments. These UPSs are characterized by high reliability, extensive monitoring capabilities (USB, RS-232, SNMP), compact design and intuitive control via LCD display. Regular diagnostics ensure stable system operation, timely detection of defects and extend battery life.
What diagnostics include
Inspection / audit
- Visual inspection of the housing, indicators, LCD display and terminal connections.
- Assessment of operating conditions: temperature, ventilation, cleanliness of the environment.
- Checking the correctness of connection to the power supply network, load and grounding system.
Electrical tests
- Measurement of input voltage, frequency, phase symmetry and stability.
- Checking output voltage, frequency, waveform under different load levels.
- Testing the UPS response to voltage surges, short-term outages and overloads.
- Evaluation of the speed of transition to battery mode and power restoration.
Inverter / bypass / charge
- Verification of the stability of the inverter operation and the absence of harmonic distortions.
- Testing the static bypass: correct switching, absence of delays and failures.
- Analysis of the charger operation: voltage, current, battery charging modes.
- Reading event logs, accidents and warnings.
Battery (battery system)
- Inspection of the battery compartment: condition of connections, absence of corrosion, integrity of the batteries.
- Measurement of the voltage on each battery module, control of charge uniformity.
- Checking the time of autonomous operation under load.
- Evaluation of the performance of the charge and discharge control system Battery.
Cooling
- Checking fan operation: speed stability, noise level, cooling efficiency.
- Temperature control of key power elements.
- Assessing the cleanliness of ventilation ducts, the presence of dust or dirt.
Communications / monitoring
- Checking the operation of the LCD display: accuracy of readings, availability of information and logs.
- Testing USB, RS-232, SNMP interfaces: correctness of data transfer, connection to monitoring software.
- Checking integration with remote monitoring systems.
Technical report
- Documenting diagnostic results: measured parameters, detected deviations, battery condition.
- Recommendations for troubleshooting and preventive maintenance maintenance.
- Suggestions for software updates or system upgrades.
When diagnostics are needed
- Scheduled — at least once a year to ensure uninterrupted operation.
- After errors, alarms or unexpected bypasses occur.
- After replacing batteries or modules.
- Before commissioning after long-term storage or transportation.
