Description
A 48VDC 20W Railway Wide Input DIP DC/DC Converter:
This 48VDC 20W Railway Wide Input DIP DC/DC Converter is rated for an output current of 417mA max with efficiency up to 88%. The input voltage is nominally 110V and covers the range of 40 – 160V with an absolute maximum of 170V. Input protection is provided by an input under voltage detector and for EMC there is an internal Pi filter. In-built OVP, OCP continuous short circuit protection are provided as standard. The output voltage accuracy is typically ±1% with line regulation of typically ±0.4% and load regulation of typically ±0.5%. Output ripple and noise is typically 50mV P-P (20MHz bandwidth).
These parts feature an industry standard 50.8 x 25.4mm DIP package with 2250VDC input to output isolation.The case is manufactured from aluminium alloy and weighs 41g. Dimensions are 50.8 x 25.4 x 12mm. The operating temperature range is -40 to +85°C and cooling is by Free air convection.
These high quality converters are designed for long operational life and have an MTBF of > 1 Million hours (MIL-HDBK-217F). They converters are specifically designed for use in railway applications, they meet UL/EN/IEC62368-1 and EN50155 approvals. Additionally these converters may be used in other commercial applications where tightly regulated outputs are required. This may include battery systems, renewable energy, data acquisition, telecom, industrial control systems and wireless networks.
