Outdoor Power Supply Failures: Waterproofing Done Right

Rain-season batch failures trace to form-factor choice, not sealant. Match the supply to the exposure.

01Symptom

Outdoor supplies fail in batches after rain — typically the first heavy season after install.

Indoor-form supplies placed outdoors, or gasket-sealed boxes that breathe and ingest water.

Semi-potted rainproof form factors for exposed positions — our JHPS line is built for it. Fully potted for washdown zones.

Classify every position by exposure (sheltered / rain / washdown) and match the form factor at order time.

Send install photos and exposure per position — form-factor recommendations within 24 hours.
