Maximum ambient temperate for full power operation at full-scale voltage is 35° C.
Constant Power Mode:
Operation at higher currents but constant power is possible from 80% of Voltage range (125% of
max. current) declining to 100% of maximum current at 100 % of voltage range for short periods
of time or at reduced ambient temperatures. (< 15 mins @ 30° C). See Figure 2-2 and Figure 2-
4.

Repetitive Peak Current
Note: Maximum Peak Current shown. Value shown reflects absolute peak current protection level. This level may not be
reached under all load conditions. Depending on load conditions, peak current may max out at lower levels due to amplifier
output impedance.
Note: A repetitive peak current limit function is provided which will generate a fault and shut off the power supply if the
peak current drawn by the load exceeds the maximum level for more than 30 seconds. During this time, the amplifier will
limit the peak current at a somewhat level above the maximum level but it is not allowable to run in this mode indefinitely.
This should provide sufficient time to ride through any startup/inrush load conditions.
