4 / 13 page Rev G DCHBW150 SERIES Up to 182 Watts Half-Brick DC/DC Converter Single Outputs 1/9/2018 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: sales@wallindustries.com Page 4 of 13 NOTES 1. Input source impedance: Power module will operate as specifications without external components, assuming source voltage has very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect stability of the power module. Since real-world voltage source has finite impedance, performance can be improved by adding external filter capacitor. 24VDC & 48VDC Nominal Input Voltage recommended capacitor: Nippon Chemi-con KY series, 100µF/100V 110VDC Nominal Input Voltage recommended capacitor: Ruby-con BXF series, 68µF/200V 2. (1) Multiple DCHBW150 series modules can be synchronized together simply by connecting the module SYNC pins together. Care should be taken to ensure the ground potential difference between the modules are minimized. (2) In this configuration all of the modules will be synchronized to the highest frequency module. (3) Up to three modules can be synchronized using this technique (4) More relevant information in application notes 3. 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 TRMI and –SENSE pins for trim down. To calculate value of the resistor RU and RD. For particular output voltage see page 5. 4. Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used, the +SENSE should be connected to corresponding +OUTPUT and likewise the –SENSE should be connected to its corresponding –OUTPUT. 5. CTRL pin is referenced to –INPUT. To order negative logic remote on/off control add the suffix “R” to the model number. Ex. DCHBW150-48S12R 6. (1) Thermal test conditions for vertical direction are by natural convection (20LFM). (2) The iron base-plate dimensions are 19” x 3.5” x 0.063” (the height is EIA standard 2U) (3) Heat sink is optional. See “Product Options” table on page 7 for suffix options. 7. CASE GROUNDING: Connecting four screw bolts to shield plane will help to reduce the EMI 8. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. 24VDC & 48VDC Nominal Input Voltage Models: 2pcs of aluminum electrolytic capacitor (Nippon Chemi-con KY series, 220µF/100V) 110VDC Nominal Input Models: 2pcs of aluminum electrolytic capacitor (Nippon Chemi-con KXJ series, 150µF/200V) 9. 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 for 7 more ordering information. CAUTION: This power module is not internally fused. An input line fuse must always be used. *Due to advances in technology, specifications subject to change without notice.
