Our industrial-grade DC/DC power converters deliver stable, reliable DC power conversion across a wide range of input voltages. Available in six input configurations (48V, 72V, 108V, 144V, 360V, and 540V) with output options of 14V, 27V, or 48V, these converters are engineered for demanding industrial, automotive, and renewable energy applications.
With power ratings from 1.0kW to 1.2kW and efficiency levels reaching up to 93%, these units minimize energy loss while maximizing system reliability.
48V model: 40–80V DC
72V model: 50–100V DC
108V model: 80–170V DC
144V model: 80–200V DC
360V model: 250–450V DC
540V model: 400–700V DC
14V output: 9–16V, up to 68A (1.0kW)
27V output: 18–32V, up to 85A (1.2kW)
48V output: 30–70V, up to 71A (1.0kW) / 44A (1.2kW) / 21A (1.0kW)
Efficiency ratings: ≥93% to ≥96% depending on model
Low power dissipation reduces cooling requirements
Integrated pre-charge resistors (30Ω or 120Ω) protect bus capacitors during startup
Bus capacitance: 7μF or 20μF per configuration
Input overvoltage & undervoltage lockout with automatic recovery
Output overvoltage protection (<16V, <33V, or <50V thresholds)
Output undervoltage protection with auto-recovery
Output overcurrent protection – shuts down above max current rating
Output reverse polarity & short circuit protection – auto-recovery after fault removal
Over-temperature protection – derating above 75°C heatsink temperature; shutdown above 95°C; auto-restart below 85°C
