REQ-003 — PCB hotspot ≤ 50°C at full load

approved · Performance · Approved by demo

Statement

The device shall not exceed 50°C (case / PCB hotspot) at full load and 25°C ambient.

Acceptance Criteria

Thermal measurement at VOUT=24V, ILOAD=1.5A per channel (both channels active), 25°C ambient; no point on case or PCB exceeds 50°C after thermal soak (30 min minimum). Measure at L1, L2, U1, U3, L3, L4.

Attempt 1 of 30 — next try in 0s

Session paused

This tab was disconnected to free server resources. The session is still held, so it can be picked up where you left off.

Could not reconnect

The server stopped answering and the automatic attempts have run out. It may still come back — trying once more costs nothing.

Could not resume

The paused session could not be restored. Reloading starts a fresh one; anything typed into this page and not yet saved will be lost.

This session has ended

This page was connected to a server that has since restarted, so there is no session left to rejoin. Reloading picks up the new one; anything typed into this page and not yet saved will be lost.
