Terminal block connector option for power supplies
Emerson Network Power has expanded its widely used Astec LP25 and LP40 switching power supply families with a new terminal block connector option.
The power adapters span a range of popular low voltage outputs, from 3.3 to 24 Vdc.
The DPT53, for example, produces +5, +15 and -15 Vdc outputs, capable of delivering up to 8.0, 2.4 and 0.5 A respectively, providing that the total demanded power does not exceed 50 Watts.
All Astec DPT50 series power adapters are high efficiency switch-mode designs that comply with the rigorous EN55022-B and FCC part 15 Level B EMC standards for conducted noise and meet all applicable immunity standards, including EN61000-4-2, -3, - 4, -5, -6, -8 and -11 levels 3.
The power supplies also carry a comprehensive set of safety approvals, including UL/CSA 60950-1,VDE/CB EN60950-1 and CE Mark.
The medical versions are fitted with fuses on both live and neutral inputs, have a maximum safety ground leakage current of 275 uA, and are additionally approved to UL/CSA60601 - 1, VDE EN60601-1 and CE Mark.
The power adapters have a full load ambient operating temperature range of 0degC to +40degC without de-rating, and are comprehensively protected against overvoltage and overpower conditions, with automatic recovery.
All models have a high demonstrated MTBF of 550,000 hours at full load and 25degC ambient.
The ac input uses a standard IEC AC 320 connector that accommodates line cords with virtually any appropriate plug configuration, and the dc outputs are provided via a 2-meter cable fitted with a standard 5-pin DIN connector.
A green LED indicates that ac power is present.
Astec DPT50 series external power adapters, including models with medical approvals, are available for immediate delivery.
Standard lead-time for both types is stock to 8 weeks.
Pricing starts at US$39.00 for the ITE/industrial models and US$44.00 for the medical models, in OEM quantities.
