SNT318 SN Inlet
|
SNT318 is a 12W inlet-type model. It is an AC/DC Power Adapter that supports a wide operating temperature range. It can also be used at 18W in environments from 0 to 40°C. It is ideal for devices that require low- and high-temperature support, such as IoT-related Products. It can also be used for general-purpose equipment. It operates in low and high temperature environments ranging from -20°C to 60°C. This Products is ideal for IoT/M2M devices. We offer models compliant with the European Ecodesign Directive (ErP Lot 7), featuring an environmentally conscious design. To meet diverse customer needs, we flexibly support small-lot customization and specification changes based on standard models. We provide optimal solutions for special applications and unique requirements, so please feel free to contact us for consideration. ProductsSeries Name:SNT318 SN Inlet |

The SN 12W Series is a desktop-type AC/DC adapter (12W class) for I.C.T./AV equipment, supporting a wide operating temperature range of -20°C to +60°C. In addition to complying with I.C.T. equipment safety standards 60950-1/62368-1, it also meets Taiwan standard CNS14336 and China standard GB4943.1, as well as PSE Appendix 8. It is a wide-temperature-range desktop power adapter suitable for powering devices used in harsh temperature environments, such as IoT, AIoT/automation equipment/ASRS (automated warehouse systems).
Output current can be switched according to the operating temperature range. It operates within a wide temperature range of -20°C to +60°C at 12W output, and within a standard temperature range of 0°C to 40°C at 18W output. Available in five models from 5.0V to 24.0V, with two AC inlet connection types (SNI318/SNT318). In addition to complying with Energy Efficiency Level VI (ErP/DoE), models compliant with ErP Lot7 are also available, reflecting an environmentally conscious design. Equipped with short-circuit/overvoltage/overcurrent protection circuits as standard. Supports LPS (Limited Power Source) and is suitable for I.C.T./AV equipment used in a wide range of temperature environments.
| UNIFIVE Reasons to Choose Us: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review for mass production adoption to certification acquisition, mass production launch, and post-production follow-up. Based on standard products, we offer flexible supply according to volume requirements, from small-lot prototyping and evaluation to small- and medium-scale production and large-scale mass production. We also support semi-custom solutions and assist with power supply selection from the specification planning stage toward mass production adoption. |
Key Features
1) Wide temperature range support (-20°C to +60°C)
Supports a wide operating temperature range of -20°C to +60°C (at 12W output). Stable power supply is possible even under harsh temperature conditions where standard AC/DC Power Adapter may not perform adequately, such as outdoor equipment in cold regions or machinery in high-temperature factory environments. Output current varies depending on the operating temperature range: 12W output operates at -20°C to +60°C, while 18W output operates at 0°C to 40°C. Safety certification has been obtained for the 0 to 40°C operating model.
2) Global safety standard compliance (including CNS14336 and GB4943.1)
Complies with I.C.T. equipment safety standards 60950-1 and 62368-1, as well as Taiwan standard CNS14336 and China standard GB4943.1. Also compliant with PSE Appendix 8, acquiring a wide range of safety certifications to support expansion into Asian markets including Japan, Taiwan, and China.
3) 5 models x 2 types, desktop design
Available in 5 models: 5.0V/5.9V/9.0V/12.0V/24.0V. Offered in 2 types (SNI318/SNT318) as desktop models with AC inlet connection. By combining with country-specific AC cords, it supports power standards worldwide. Compact desktop design with dimensions of 75.0 x 29.8 x 50.6mm.
4) ErP Lot7 compliant models available
Energy Efficiency Level VI (ErP/DoE) compliant, meeting EU Commission Regulation (EU) 2019/1782 and DOE 10 CFR Part 429/430.
