PS-200 power supply accepts a 115, 230 or 24 VAC
input and provides a 5 to 25 VDC output that is both fully
regulated and protected from short circuiting and thermal
The PS-200 incorporates an inline fuse and terminal strip
voltage and multiple-position terminal strips
for the DC output. Two unique
options are available for the PS-200, making it
one of the most versatile, reliable,
indestructible, easy to install, and stable
in the industry.
PS-200 is a reliable, stable, and fully protected DC power supply
designed to power all control peripherals. Other open-frame
linear power supplies require expensive field
modifications for adding an inline fuse, soldering a
primary line voltage
and secondary DC output leads, and engineering
a bracket to mount the power supply. To address these
time-consuming and costly modifications, MAMAC Systems
developed a power supply which eliminates all of the above expensive field modifications.
PS-200 incorporates a split bobbin transformer
with 3500 VRMS isolation between the windings to
provide reliable and consistent secondary output. The
line voltage is fuse protected, and the fuse holder
on a bracket to make it easily accessible
purposes. A conveniently located terminal
strip is provided for the line voltage termination, and
voltage connections — including the
fuse holder and the terminal strip — are
fully insulated to protect
against accidental electrical shock hazard.
In addition, the fuse holder accepts industry standard
3AG fuses which are
readily available. Furthermore, the PS-200's
options of 115 VAC, 230 VAC or 24 VAC ensure that the
power supply will perform with any
available line voltage.
PS-200 utilizes a full wave bridge rectifier to
convert secondary AC voltage to a DC output. A single
reliable voltage regulator is used to provide a
stable and regulated output with built-in short circuit,
thermal overload, inrush, and line voltage spike protection.
Significantly, the output of the PS-200 can be
indefinitely shorted without damaging the power supply,
and if the load exceeds the rated specification, the power
supply shuts down and goes into a dormant state. As soon
the overload condition is removed, the power supply
resumes functioning without any damage. In this
way, our PS-200 is a highly reliable and indestructible
power supply for the controls industry.
high-grade, low ESR, and low-leakage capacitors
filter DC voltage and provide
mV pp ripple on the output. A multi-turn
trimmer allows output adjustment from 5 to
25 VDC. Once adjusted, the output remains constant regardless

Furthermore, each PS-200 is shipped with
its output adjusted to a customer's requirements. In addition,

order to facilitate installation of
our PS-200 in a control panel, MAMAC Systems offers
two unique chassis options for the power supply--
a low-height chassis designed for shallow panels and a
deep panels where horizontal space is limited.
Both chassis function as heat sinks and are
with recessed components to provide a flush
mounting surface without stand-offs
two chassis options, fully adjustable output, short
circuit and thermal overload protection, inrush
and spike protection, fuse protection on line voltage,
and an easily accessible terminal strip for supply
and output voltages, our PS-200 is not only the most reliable,
indestructible, stable, and versatile power supply
in the industry, but also requires the least amount
of installation time in control panels.
