1. SMPS & UPS Maintenance
AC-DC Conversion: Monitor and service SMPS rectifiers converting grid or DG AC input into secure -48V DC power for base transceiver stations (BTS) and telecom gear.
Battery Bank Management
Routine Checks: Measure individual cell/string voltages, specific gravity (for flooded lead-acid), and temperature sensors.
Capacity & Discharge Testing: Conduct periodic battery discharge tests to identify weak or dead cells.
Charging Control: Verify float and boost charging configurations via the SMPS controller to prevent overcharging or deep discharge.
Terminal Maintenance: Clean corroded terminals, apply petroleum jelly/anti-oxidant paste, and check torque specs on battery links.
Fault Finding & Alarm Monitoring
NOC Coordination: Respond to power alarms (mains fail, low DC voltage, rectifier failure, battery on-discharge) escalated by the Network Operations Center (NOC).
Diagnostic Tools: Use multimeters, clamp meters, and insulation testers to trace shorts, ground faults, or voltage drops.
Safety & Documentation
Logbooks: Maintain daily checklists, energy readings, breakdown logs,



and site visit reports.
Safety Protocols: Adhere strictly to electrical isolation, Lockout/Tagout (LOTO), and PPE guidelines.
Module Replacement: Handle hot-swappable SMPS rectifier modules and repair or replace faulty sub-units without dropping site power.
UPS Servicing: Maintain online UPS setups, static transfer switches, and distribution units supporting critical indoor telecom loads.
Parameter Tuning: Calibrate output voltage, current limits, and load-sharing parameters across parallel power modules.
Education: ITI or Diploma in Electrical, Electronics, or Electrical & Electronics Engineering.
Experience: 2 to 5 years of hands-on experience in telecom passive infrastructure or critical power maintenance.
Key Competencies: Deep understanding of DC power plants, battery chemistry (VRLA/Lithium-ion), single-line electrical diagrams, and fault diagnostic procedures
