Over Temperature Protection (OTP)
The OTP function allows you to select how the power supply recovers
from an over temperature shutdown using the rear panel switch SW1-8.
See
Table 3-3 for the switch settings and selections. See “Rear Panel
Connectors and Switch” on page 1–5 for more information about the
switch. The OTP shutdown circuit activates before the internal
components can exceed their safe internal operating temperatures. When
an OTP shutdown occurs, the front panel OTP LED turns on.
