1.4.5 COOLING REQUIREMENTS
All BOS/S units use forced air cooling. The side and rear panels of the BOS/S
must be clear from objects that could impair circulation, a minimum of 4 inches
of clearance is required. Rack mounting is allowed provided air flow is
adequate.
1.4.6 OVERTEMPERATURE PROTECTION
An internal thermostat will disable the unit when the internal heatsink reaches
195°F.
1.5 FOUR QUADRANT OPERATION
The BOS/S is capable of sourcing and sinking current making it a true four quadrant
power supply. In Quadrants II and IV, the average power dissipation must be derated
as per Figure 1.4.7.1 below. Average power is the average power dissipated over 30
seconds.
