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 modifications to add inline fuse, solder primary line voltage and secondary DC output leads, and to engineer a bracket to mount the power supply. To address the above issues, 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. All line voltage connections, including the fuse holder and the terminal strip, are fully insulated to protect against accidental electrical shock hazard. The fuse holder accepts industry standard 3AG fuses which are readily available. The PS-200 is available with either 115 VAC, 230 VAC or 24 VAC line voltage options. These features enable the PS-200 to perform with any available line voltage.

PS-200 utilizes a full wave bridge rectifier to convert the secondary AC voltage to a DC output. A single I.C. reliable voltage regulator is used to provide a stable, regulated output with built in short circuit, thermal overload, inrush and line voltage spike protection. The output of the PS-200 can be indefinitely shorted without damaging the Power Supply. Similarly, if the load exceeds the rated specification, the PS-200 output 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 very reliable, indestructible power supply designed for the controls industry.

Multiple high grade low ESR and low leakage capacitors are used to filter the DC voltage and to provide less than 2.0mV pp ripple on the output. A multi-turn trimmer is provided to adjust the output from 5.0 to 25.0 VDC. Once adjusted, the output remains constant regardless of line voltage fluctuations or output load variations. Each PS-200 is shipped with the output adjusted to a specific value as desired by the customer. Multiple position terminal strips are provided for field wiring.

In order to facilitate the installation of our PS-200 in a control panel, MAMAC Systems. has developed two unique chassis options: 1) a low height chassis designed for shallow panels; 2) a narrow width chassis for deep panels where horizontal space is a premium. Both the chassis function as a heat sink and are engineered such that all the components are recessed to provide a flat surface for flush mounting in a control panel without stand-offs or spacers.

With two packaging options, fully adjustable output, short circuit and thermal overload protection, inrush and spike protection, fuse protection on line voltage and 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.
