GAPTEC-Electronic GmbH & Co. KG sales@gaptec-electronic.com – www.gaptec-electronic.com Page 1 of 3 20DMW_1.5 – Rev. 2016-1.1 Specifications subject to change without notice. 20DMW_1.5 Series 20W - Single/Dual Output - Ultra Wide Input - Isolated & Regulated DC-DC Converter Wide 2:1 input voltage range High efficiency up to 90% Remote On/Off Input/output isolation voltage: 1.5K Vdc Short circuit protection (SCP) RoHS compliant Operating temperature range: -40°C to +85°C Over voltage protection: clamp mode Shielded metal case with insulated baseplate 20W DIL PACKAGE Standard 1”x1” package Customer design available DC-DC Converter 20 Watt The 20DMW_S & 20DMW_D series are isolated 20W DC/DC converters. Designed with high efficiency, they allow the operating temperature ran - ge of these units to be -40°C to +85°C (with derating) in a 6 pin DIP package with industry-standard footprint. Further features include wide 2 : 1 input voltage range, remote on/off control, trimmable output, short- circuit protection and over voltage protection. These converters are well suitable for battery operated equipment, mea - surement equipment, telecom, wireless network, Industry control sys - tem, everywhere where isolated, tightly regulated voltages and compact size are required. Common specifications Short circuit protection: Hiccup, continuous, automatic recovery Cooling: Free air convection Operation temperature range: -40°C~+85°C Storage temperature range: -55°C~+125°C Maximum case temperature: 100°C MAX Soldering temperature: 265°C MAX for 10 sec. Switching frequency: 330kHz TYP Storage humidity range: 95% MAX Safety standards: EN 60950-1, IEC 60950-1 Vibration and thermal shock: MIL-STD-810E Case material: Nickel-coated copper (six-sided) Base material: Non-conductive black FR4 Potting material: Epoxy (UL94V-0) MTBF (MIL-HDBK-217F @25°C): 340,000 hours Weight: 16.5g Input specifications Item Test condition Min Typ Max Units Input surge voltage (100ms max.)
