RECOM DC-DC Converter, 1kV DC Isolation Voltage, 78 to 83% Efficiency - RI Series - RI-0505S


In search of a space-saving voltage conversion solution? Look no further than this DC-DC converter from RECOM. It comes in a Compact SIP-4 package with dimensions of 11.5 (L) x 7.55 (W) x 10.2mm (H) and has a power rating of 2W. This gives it impressive power density, so it keeps high-load devices charged up while using minimal space on your PCB. An efficiency rating between 78 and 83% means the unit wastes little energy as heat, so it doesn't need a heatsink and won't lose its cool in demanding applications. Thanks to an isolation voltage of 1kV DC, powerful electrical surges are brushed off and your equipment can carry on with business as usual.

• Non-flammable housing for safety in the event of a fire

• Maximum capacitive load of 1200μF enables start-up in 1s without risk of damage to connected devices

• Wide operating temperature range of -40°C to +85°C for use in harsh environments

Applications


• Autonomous mobile robots

• Laser-guided vehicles

• Industrial automation

• Telecommunications

How long will this converter last?


This converter has a mean time between failures of 17,900,000 hours at +25°C, so you can rest assured it's with you for the long haul.
