MAMAC Systems PS-200-1-A-3-N Power Supply

The MAMAC Systems PS-200-1-A-3-N is a heavy-duty 24Vdc output power supply designed for the rigorous demands of industrial control panels and HVACR automation. This unit accepts a 24Vac input voltage and provides a highly stable 1.5 Amps output current, delivering a clean, filtered, and regulated DC signal with less than 2.0 mV peak-to-peak ripple. Engineered with a specialized narrow width chassis, it optimizes rail space in deep control enclosures without requiring external stand-offs or spacers. Unlike standard open-frame linear supplies, this model features a split bobbin transformer with 3500 VRMS isolation and an integrated 3AG inline fuse, eliminating the need for expensive field modifications during installation. The adjustable DC voltage range (5 to 25 Vdc) ensures precision when powering sensitive BAS controllers, pressure transducers, and chemical sensors. With built-in thermal overload protection and indefinite short-circuit resilience, this 24Vdc power source is built for consistent performance in high-stakes environments.

• Panel Space Optimization: The narrow width chassis allows for high-density mounting in deep control cabinets where horizontal space is at a premium.
• Advanced Signal Integrity: Provides regulated DC power with minimal ripple, ensuring that sensitive analog sensors and HVAC controllers operate without signal noise.
• Circuit Safety: Features an easily accessible inline fuse and short circuit protection that resets automatically once the fault is cleared, maintaining uptime.
• Reliable Isolation: High-performance split bobbin transformer provides 3500 VRMS isolation to protect downstream peripherals from line voltage interference.

Can the output voltage be adjusted for specific device requirements?
Yes, the PS-200-1-A-3-N features a multi-turn trimmer that allows a technician to fine-tune the DC output between 5.0 and 25.0 Vdc to match the specific calibration needs of HVACR equipment.

How does this unit handle over-current or short-circuit conditions?
This regulated power supply is designed to handle indefinite short circuits. If the load exceeds the 130% current limit, the unit enters a dormant state and resumes normal operation once the overload is removed.

Is this power supply suitable for noisy electrical environments?
Absolutely. The filtered DC output and line voltage spike protection make it an ideal choice for mechanical rooms where VFDs or large motors might otherwise cause electrical interference.
