1 / 6 page Wall Industries, Inc. 37 Industrial Drive Exeter, NH 03833 02/24/2010 603-778-2300 www.wallindustries.com Fax 603-778-9797 Page 1 of 6 DMW Ultra Wide Series Single and Dual Output 4:1 Ultra Wide Input Voltage Range Up to 15.3 Watts DC/DC Converters Rev C FEATURES ● 1500VDC Isolation ● 4:1 Ultra Wide Input Range ● Six-Sided Shielding ● UL 94V-0 Package Material ● Efficiency up to 86% ● UL60950-1 Safety Approval ● MTBF > 700,000 Hours ● Complies with EN55022 Class A ● Internal SMT Construction ● Positive Remote On/Off Control (Optional) DESCRIPTION The DMW series of DC/DC converters provide up to 15 watts in a 2 x 1 x 0.4 inch package. These converters operate over 4:1 wide input voltage ranges of 9-36VDC and 18-75VDC. This series also has single and dual output models available. These converters feature efficiency up to 86%, positive remote ON/OFF (optional), six-sided shielding, 1500VDC isolation, and short circuit protection. This series is ideal for data communication equipment, mobile battery driven equipment, process/machine control equipment, telecommunication equipment, computer peripheral systems, distributed power systems, mixed analog/digital subsystems, and industrial robot systems. The EN55022 Class A conducted noise compliance minimizes design time, cost, and eliminates the need for external filter components. SPECIFICATIONS: DMW Ultra Wide Series All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted. We reserve the right to change specifications based on technological advances.
