DD

The DD Series offers 60 watts of output power from a 2.02 x 2.02 x 0.4 inch package. The DD series operates off 2:1 wide input voltage ranges of 18-36VDC and 36-75VDC and features 1600VDC of isolation, short-circuit and over-voltage protection, as well as six sided shielding. All models are ideally suited to telecommunications, industrial, mobile telecom and test equipment applications.

● Single Output Up to 14A ● High Efficiency up to 91% ● RoHS Directive Compliant ● Fixed Switching Frequency ● No Minimum Load Required ● Six-Sided Continuous Shield ● 2:1 Wide Input Voltage Range ● Approved for Basic Insulation ● 60 Watts Maximum Output power ● Standard 2.02” x 2.02” x 0.4” Package

Notes & safety
Notes: 1. Maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used the +Sense should be connected to the +Output and the -Sense should be connected to the -Output.
2. The On/Off control function is positive logic (negative logic optional). The pin voltage is referenced to the negative input. To order negative logic On/Off control add the suffix "R" (Ex: DD48S5-12000R).
3. BELLCORE TR-NWT-000332. Case I: 50% stress, temperature at 40°C. (Ground fixed and controlled environment.) MIL-STD-217F Notice2 @ Ta=25°C, full load (ground benign controlled environment).
4. Heat sink optional - contact factory for details.
5. The DD series requires an external filter to meet EN55022 Class A emissions.
Due to advances in technology, specifications are subject to change without notice.
