Notes & safety
Notes: (1) Typical value at nominal input voltage and no load.
(2) Typical voltage at nominal input voltage and full load.
(3) The ripple and noise of output voltages 24VDC and 28VDC is measured with a 4.7µF/50V 1812 X7R MLCC;
The ripple and noise of output voltages 48VDC and 53VDC is measured with a 2.2µF/100V 1812 X7R MLCC.
The ripple and noise of all other output voltages is measured with a 1µF/25V X7R MLCC and a 22µF/25V D-type POS-CAP.
(4) Test by minimum input and constant resistive load.
(5) The CTRL pin voltage is referenced to –INPUT. To order negative logic remove on/off control add the suffix “R” to the model number (Ex: DCHB150-48S12R).
(6) Output voltage is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting a single resistor between TRIM and +SENSE pins for trim up or between TRIM and –SENSE pins for trim down. Maximum output deviation is inclusive of remote sense. To calculate the value of the resistor RU and RD for a particular output voltage see page 6.
(7) Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used the +SENSE should be connected to its corresponding +OUTPUT and likewise the –SENSE should be connected to its corresponding –OUTPUT.
(8) - Thermal test conditions for vertical direction are by natural convention (20LFM)
- The iron base-plate dimensions are 19” x 3.5” x 0.063” (the height is EIA standard 2U).
- Heat sink is optional.
(9) The DCHB150 series can only meet EN55022 Class A or Class B with external components added. Please contact factory for more information.
(10) An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. We recommend connecting two aluminum electrolytic capacitors (Nippon chemi-con KY series, 220μF /100V, ESR 48mΩ) in parallel.
(11) CASE GROUNDING: EMI can be reduced when you connect the four screw bolts to the shield plane.
(12) Input Source Impedance: These converters will meet all listed specifications without external components assuming that the source voltage has very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the converter. Since real-world voltage sources have finite impedance, performance can be improved by adding an external filter capacitor. We recommend Nippon chemi-con KY series, 100μF/100V, ESR 110mΩ.
(13) - Multiple DCHB150 series modules can be synchronized together simply by connecting the module SYNC pins together. Care should be taken to ensure the ground potential differences between the modules are minimized.
- In this configuration all of the modules will be synchronized together to the highest frequency module.
- Up to three modules can be synchronized using this technique.
- More relevant information in application notes.
(14) This series comes with several different options: negative remote on/off control, heatsinks, case pin, sync pin, pin length, terminal block, and thru-hole inserts. See the “Product Options” table on page 6 for more ordering information.
CAUTION: This power converter is not internally fuses. An input line fuse must always be used
Due to advances in technology, specifications subject to change without notice.
