| Notes & safety | |
| Notes: | 1. Part number with suffix “H” are heat sink mounting, parts with suffix “A2S” are chassis mounted, parts with suffix “A4S” are DIN Rail mounted, for example DCURB2405-20WHA2S is chassis mounted with heat sink. We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements. 2. The A2S and A24 models start-up and minimum input voltages are increased by 1VDC due to input reverse polarity protection circuit. 4. Maximum capacitive load offered were tested at nominal input voltage and full load. 5. Efficiency measured at nominal input and rated output load. Efficiency of A2S and A4S is decreased by 2% due to input reverse polarity protection circuit. 6. Ctrl pin voltage is referenced to input GND. 7. Under 0%-5% load conditions, ripple & noise does not exceed 5%Vo. The “parallel cable” method is used for Ripple and Noise test, contact factory for more information. 8. Switching frequency is measured at full load. Module reduces switching frequency for light load (below 50%) efficiency improvement. 9. This product is Listed to applicable standards and requirements by UL. 10. Customization is available 11. Products shall be classified according to ISO14001 and related environmental laws and regulations and should be handled by qualified units. *Due to advances in technology, specifications subject to change without notice. |
