MAMAC Systems PS-200-1-B-1-N Power Supply

For high-performance control environments, the MAMAC Systems PS-200-1-B-1-N is a technician-grade 24Vdc power supply engineered for standard 115Vac line voltage. Built on a narrow width chassis, this unit is the go-to choice for deep control panels where horizontal rail space is at a premium. Unlike consumer-grade alternatives, it utilizes a split bobbin transformer with 3500 VRMS isolation, ensuring a clean, filtered, and regulated DC output with less than 2.0 mV peak-to-peak ripple. This level of signal stability is critical for sensitive HVACR sensors and transducers that are prone to interference in high-EMI environments. The PS-200-1-B-1-N (identical to MAC-PS200-1B1-N) features a 3.0 Amp output current, providing ample overhead for multiple control peripherals. It includes an inline fuse for primary protection and a multi-turn trimmer for precise voltage regulation. Designed for reliability, the chassis power supply is internally protected against thermal overload and short circuits, entering a dormant state during faults and auto-resetting once the condition is cleared.

• Space-Efficient Design: The narrow width chassis allows for high-density mounting in congested electrical cabinets.
• Superior Signal Isolation: Split bobbin transformer technology protects low-voltage controllers from line-side transients and noise.
• Field-Serviceable Protection: Features an easily accessible 3AG inline fuse for rapid troubleshooting and maintenance.
• High Power Density: Delivers a consistent 3.0 Amps output current at 24Vdc, sufficient for powering medium-to-large control loops.
• Indestructible Logic: Engineered with thermal overload protection and short-circuit recovery to prevent board failure during field wiring errors.

Can I adjust the output voltage if my long-run sensor loop has a voltage drop?
Yes. This unit includes a multi-turn trimmer that allows you to adjust the 24Vdc output to compensate for line loss, ensuring your distal peripherals receive the required operating voltage.

Will this power supply fit in a shallow control box?
This specific model uses the "N" (Narrow) chassis, which is designed for depth. If you have a shallow panel, you may need the "A" (Low Height) chassis variant; please verify your clearance before installation.

How does this handle an accidental short during commissioning?
The PS-200-1-B-1-N is designed to shut down and go dormant if it detects a short circuit or an amp draw exceeding 130% of its rating. Once the short is removed, the regulator automatically resumes normal operation without requiring a manual reset of the internal circuitry.
