RECOM DC-DC Converter, 1kV DC Isolation Voltage, 1 Output - RS3 Series - RS3-0509S

Add an extra layer of safety between your equipment and its power source using this DC-DC converter from RECOM. It offers an electrical barrier between its input and output that helps to protect against electric shock and stop power surges from damaging devices. The component also gives you the benefit of a stable 9V DC output to keep systems running reliably. A typical efficiency between 77 and 80% means minimal power is wasted as heat during stepping up, eliminating the need for a heat sink.

Features & Benefits

• MTBF of over 33 million hours for an extended service life

• Wide operating temperature range between -40°C and +71°C makes it suitable to use in demanding settings

• Flame-retardant housing that helps reduce the spread of fire

• Light weight of 4.7g puts minimal strain on a PCB

Applications

• Medical power supplies

• Test and instrumentation equipment

• Industrial automation

Is this DC-DC converter prone to voltage spikes?

As the unit generates minimal ripple and noise, there's little chance of it causing power spikes in your voltage output.
