RECOM DC-DC Converter, 1kV DC Isolation Voltage, 73 to 75% Efficiency - RS3 Series - RS3-123.3S

Seeking stable output voltages from an unregulated power source? Opt for this DC-DC converter from RECOM. It accepts inputs from 9 to 18V DC to produce a dependable, regulated output of 3.3V DC for safe use with your sensitive battery-powered components. Thanks to its Compact dimensions of 21.8 (L) x 9.2 (W) x 11.1mm (H) and its power rating of 3W, it packs a powerful Punch for its small size. An efficiency rating between 73 and 75% means this converter wastes little energy as heat, so it can keep its cool without the need for a heatsink.

• Remote on/off feature lets you control device functions at a distance

• Continuous short-circuit protection shields you and your equipment from electrical hazards

• Flame-retardant construction minimises the spread of fire

• Low maximum ripple and noise of 50mVp-p mean you GET stable output voltages with less risk of damaging spikes

Applications

• Telecommunication networks

• Medical equipment

• PCBs

• Industrial control circuits

What temperatures can I use this DC-DC converter in?

This component works in a broad operating temperature range of -40°C to +71°C, so you count on it in demanding industrial environments.
