Operating Temperature
The DS1200-3 series power supplies will start and operate within stated specifications at an ambient
temperature from -10 °C to 50°C under all load conditions with internal fan. DS1200-3-002 and DS1200-3-401 can
operate up to 70 °C with derated power.
Forced Air Cooling
The DS1200-3 series power supplies included internal cooling fans as part of the power supply assembly to provide forced
air-cooling to maintain and control temperature of devices and ambient temperature in the power supply to appropriate
levels. The standard direction of airflow is from the DC connector end to the AC connector end of the power supply.
The cooling fan is a variable speed fan. The fan speed is controlled by the PWM duty cycle of the fan supply voltage
depending on the main output 12V load condition per below table:
