Product Options
Performance and Packaging Options
Magna-Power Electronics programmable DC power supplies are designed to be as versatile and expandable as possible. A variety
of options are available allowing the product to deviate from its standard specifi cations. This section provides an overview of the
available performance and packaging options and products supported.
High Isolation Output
Option Code: +ISO
Products Supported: TS Series, MS Series, MT Series
Certain applications require fl oating the output voltage to
values beyond the power supply’s standard isolation rat-
ing. Magna-Power Electronics High Isolation Output option
(+ISO) enables any TS Series, MS Series, or MT Series
model with a peak output voltage rating of 250 Vdc through
1000 Vdc to be rated for a higher voltage output isolation.
Improved isolation is achieved by a novel output stage with
improved controller isolation. In addition to being able to
fl oat the power supply to a higher output voltage, this option
also enables lower voltage units to connected series up to the
higher isolation rating.
The table below provides the output isolation rating for all
available confi gurations, where Vo is the unit’s rated maxi-
mum output voltage.

High Slew Rate Output
Option Code: +HS
Products Supported: XR Series, TS Series, MS Series, MT Series
The high slew rate option solves several limitations inherent in switching power supply design. Rapid voltage transitions
require internal electronics to supply the energy to charge and discharge output capacitors. Peak currents internal to the
power supply defi ne slew rate; utilizing less capacitance enables voltage transitions in shorter time periods. Additionally,
less capacitance reduces requirements for discharge demands during open circuit conditions.
The standard output stage Magna-Power Electronics power supplies has been designed to provide the lowest possible output
ripple voltage within the constraints of available components, size, and cost. Part of the output stage consists of a bank of
aluminum electrolytic capacitors which has the desired electrical properties to provide this function. These components
require bleed resistors to discharge any voltage when the power supply has no load and is disabled. While the presence of
these components and the resulting performance are normally industry accepted,
there are applications where lower output capacitance is extremely desirable and
higher ripple voltage is acceptable. To meet this need, a high-slew rate option is avail-
able which has an output stage consisting of low capacitance fi lm and aluminum elec-
trolytic capacitors. Applications for the high-slew rate option include battery charg-
ing, photovoltaic emulation, power waveform generation, and medium speed power
pulsing. These applications all benefi t from higher bandwidth and in many cases, can
tolerate the increased ripple voltage of this option.
