RoHS

The 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 overloads. The PS-200 incorporates an inline fuse
and terminal strip for the primary line voltage and multiple-position terminal
strips for the DC output. Two unique chassis options are available for the
PS-200, making it one of the most versatile, reliable, indestructible, easy to
install, and stable power supplies in the industry.

PS-200

The 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.

Our 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 is mounted
on a bracket to make it easily accessible for
replacement purposes. A conveniently located
terminal strip is provided for the line voltage
termination, and all line 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 line voltage options of 115 VAC, 230
VAC or 24 VAC ensure that the power supply
will perform with any available line voltage.

The PS-200 utilizes a full wave bridge rectifier to
convert secondary AC voltage to a DC output.
A single I.C. 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 as the overload condition is removed, the

power supply resumes functioning without any
damage. In this way, the PS-200 is a highly
reliable and indestructible power supply for the
controls industry.

Multiple high-grade, low ESR, and low-leakage
capacitors filter DC voltage and provide less
than 2.0 mV pp ripple on the output. A multi­turn trimmer allows output adjustment from 5
to 25 VDC. Once adjusted, the output remains
constant regardless of line voltage fluctuations
or output load variations. Furthermore, each
PS-200 is shipped with its output adjusted to a
customer's requirements. In addition, multiple­position terminal strips are provided for field
wiring.

In order to facilitate installation of the 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 narrow-width chassis for deep panels
where horizontal space is limited. Both chassis
function as heat sinks and are engineered with
recessed components to provide a flush mount­ing surface without stand-offs or spacers.

With 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.
