| Notes & safety | |
| Notes: | 1. Several options are available for this series. Horizontal package is the standard. To indicate a chassis mount option, add “C” to end of model number. To indicate DIN rail mount option, add “D” to end of model number. Heatsink is also available for all models. If application has a higher requirement for heat dissipation, heatsink is recommended. To indicate heatsink, add “H” to end of model number. 2. Due to input reverse polarity protection function, minimum value and starting voltage input voltage range for chassis and DIN rail mount models is higher than 1VDC DIP package. 3. Efficiency is measured in nominal input voltage and rated output load. Due to input reverse polarity protection for chassis and DIN rail mount models, minimum efficiency greater than Min.-2 is qualified. 4. This series of products uses reduced frequency technology, the switching frequency is test value of full load. When the load is reduced to below 50%, the switching frequency decreases with decreasing load. 5. Customization available, please contact factory. 6. Products classified according to ISO14001 and related environmental laws and regulations and should be handled by qualified units. 7. This product is Listed to applicable standards and requirements by UL. *Due to advances in technology, specifications subject to change without notice. |
| Safety Approvals: | IEC60950, UL60950, EN60950 |
