Overall Dimensions: 61mm (L) × 30mm (W) × 18mm (H)Housing Material: Flame-retardant engineering plastic (UL94 V-0 grade), with insulating coating on the surfaceWeight: Approximately 70gMounting Method: PCB onboard soldering installation, supporting 35mm DIN rail auxiliary fixing (with adapter bracket required)Wiring Method: Through-hole pin interface, adapting to 1.27mm pitch padsStatus Indication: Built-in power output LED indicator (steady green for normal, blinking for fault)
Environmental Parameters
Operating Temperature: -20℃ to +70℃ (non-condensing environment)Storage Temperature: -40℃ to +85℃Relative Humidity: 5% to 95% (non-condensing)EMC Compliance: Complies with EN 55022 Class B (emission limits) and EN 55024 (immunity) standardsVibration Resistance: 10-500Hz frequency range, 0.3g acceleration (sine wave)
Product Performance
High conversion efficiency: ≥90% power conversion rate significantly reduces energy consumption and heat dissipation requirements. No additional heat sink is needed to maintain stable temperature during full-load operation, reducing the complexity of system heat dissipation design.
Strong output stability: Ripple and noise are controlled within 100mVpp. The filter circuit can effectively suppress mains fluctuation interference, providing low-noise power for precision electronic components and ensuring equipment operation accuracy.
Comprehensive protection mechanism: Four-fold electrical protection (overvoltage, undervoltage, overcurrent, short-circuit) and thermal shutdown function form all-round protection, which can respond quickly in fault states to avoid damage to the module and load equipment.
Excellent integration adaptability: Compact size (61×30×18mm) facilitates embedding into equipment with limited space. The through-hole pin design supports automated assembly line soldering, adapting to mass production scenarios.
Good environmental tolerance: -20℃ to +70℃ operating temperature range covers most industrial and commercial scenarios. Anti-electromagnetic interference design ensures stable operation in complex electromagnetic environments such as base stations and automated workshops.
