APPLICATION
The EC7BW18-72 Series of DC-DC converters offer 20 watts of output power with output voltages of 5V, 12V, 15V, ±12V, ±15V, ±24V dc. The EC7BW18 series comes in a compact chassis or Din rail mount package along with associated filter components. It has an ultra-wide (16:1) input voltage range of 10 to 160VDC (72VDC nominal) and 3000V ac reinforced input to output isolation.
The EC7BW18-72 ECRT/EDRT series is compliant with EN50155, EN45545, EN50121-3-2 without the need for any external components, making it ideal for all railway applications. It also meets RIA12 surge A requirements on 24V and 52V systems.
Units are fully protected against input UVLO (under-voltage lockout), output over-current, output over-voltage, and over-temperature and continuous short circuit conditions.
EC7BW18-72 ECRT/EDRT series is designed primarily for railway applications and covers all standard battery voltages of 24V, 36V, 48V, 72V, 96V, 110V dc. It is also suitable for distributed power architectures, telecommunications, battery-operated equipment, and industrial applications.
