Description
The versatile 5 Watt Dual Output converter is particularly
suitable for use in microprocessor systems where 5 Volts is
the primary power source, and where a low noise plus and
minus output voltage is required.
The shielded transformer provides low I/O capacitance
and high common mode input to output isolation.
The low guaranteed output noise of 20mV P-P maximum is
achieved by a built-in linear post regulator.
Available in standard 6 sided shielding, or the -5 model
which has 5 sided shielding and is water washable.
Each converter is completely specified, fully ATE tested,
contains overload protection, and is covered under CALEX’s
5 year warranty.
