Socomec DELPHYS MP Elite+ — a highly reliable three-phase uninterruptible power supply system with an online double-conversion topology, designed to protect critical facilities in the data center, telecommunications, industry and energy sectors. This model provides maximum voltage and frequency stability, supports extended parallel operation, has an advanced cooling and communications system, adapted for difficult operating conditions. Diagnostics includes checking all major components, including the power unit, batteries, cooling, and monitoring system.
What diagnostics include
Inspection/audit
- Visual assessment of the housing, control panel, indicators, and connections.
- Fixing the system configuration: operating mode, presence of external bypass, number of battery cabinets.
- Analysis of operating conditions: temperature, humidity, dust level, compliance with IP protection requirements.
- Checking the electrical installation: correct connections of phases, neutral, and grounding.
Electrical tests
- Measurement of input voltage and frequency, checking phase symmetry.
- Output voltage control: stability, accuracy, quality signal.
- Testing switching modes between inverter, mains power and bypass with recording of response time.
- Checking the system's response to overloads and short-term power fluctuations.
Inverter / bypass test
- Evaluating the stability of the inverter under different loads.
- Checking the operation of automatic and manual bypass: switching time, absence of distortion.
- Synchronization of phases and frequencies when switching between modes.
- Reading event logs, analyzing errors and emergencies.
Battery (battery system)
- Inspection of battery cabinets for mechanical damage, corrosion, overheating.
- Measuring the voltage of individual battery modules, checking balance and capacity.
- Charger check: charging modes, current and voltage parameters.
- Standalone test (with customer consent): determining the UPS battery operation time under load.
Cooling
- Checking fan operation: speed, noise level, automatic adjustment.
- Analysis of temperature sensors in key areas: power modules, battery compartment.
- Inspection of ventilation ducts and filters for contamination.
Communications / monitoring
- Interface testing: local display, RS-485, Modbus, SNMP, dry contacts.
- Checking data transmission to SCADA, BMS or other external monitoring solutions.
- Assessing the integrity of the connection, the correctness of the display of parameters and event logs.
Technical report
- Preparation of a detailed report on the inspections, measurements and testing carried out.
- Conclusions on the condition of the inverter, batteries, cooling and monitoring system.
- Recommendations for maintenance, component replacement, software updates.
When diagnostics are needed
- Regularly — as part of scheduled maintenance, according to the manufacturer's recommendations.
- After accidents or malfunctions that affected the stability of the power supply.
- When changing the load configuration or updating the battery system.
- Before commissioning after a long downtime or conservation.
