One of the most important measures taken when it comes to fire protection is, ensuring the quality of the fire protection systems and that PSUs are up to standard. Entire fire systems with all the advanced features that come with them rely on the power supply! The obvious choice is to insist on a high-quality and certified PSU built for reliability and longevity in varying temperatures.
But how do you combat varying temperatures and protect your PSU from them?
What to look out for in varying temperatures
It is crucial to ensure that PSUs can perform in hot or cold environments! As a best practice, try to keep your power supply installations in a well-protected, sheltered area. Ideally, this would be out of reach from the elements and prevent anyone from tampering with the PSU. The surrounding environment, whether an indoor room or a less insulated outdoor room, must be considered when choosing a power supply.
Ensuring your power supply is rated to withstand temperatures than the environment where it will be used is also important. Doing this ensures that your power supply can hold up to the environment it will be placed in.
We’ve put together some PSU features that we recommend you look for when considering an installation that could be susceptible to varying temperatures:
- Vented module enclosures, vented power supply enclosures, heatsink, and component thermal wicking/transfer design.
- Electronic temperature compensation: When built into PSU modules, this ensures stability.
- Battery temperature monitoring: This will help to control charging characteristics.
- Overcurrent shutdown protection will help stop the PSU from overheating in hot environments.
