Description
The second generation COOLSET™-F2 provides several
special enhancements to satisfy the needs for low power
standby and protection features. In standby mode
frequency reduction is used to lower the power
consumption and support a stable output voltage in this
mode. The frequency reduction is limited to 21.5 kHz to
avoid audible noise. In case of failure modes like open loop,
overvoltage or overload due to short circuit the device
switches in Auto Restart Mode which is controlled by the
internal protection unit. By means of the internal precise
peak current limitation the dimension of the transformer and
the secondary diode can be lower which leads to more cost
efficiency.
