Description
The 4:1 input range of the LE Triple Series makes them ideal
for a wide variety of power requirements including battery and
unregulated input applications. Each converter鈥檚 +5V is
tightly regulated and useful for driving standard logic circuits.
These 27-30 Watt converters have dual output filters. They
provide a low output noise of 50 mV P-P typical and are fully
specified and tested to the maximum specifications. Input
filtering significantly reduces the reflected ripple noise.
Unlike comparable converters, all inputs and outputs are
protected from transient overvoltage conditions. Overload
protection is provided by current sensing of the primary
switching current and an independent thermal sensor. The
27-30 Watt Triple Series, like all CALEX converters, carries
the full 5 Year CALEX Warranty.
