MAMAC Systems PS-200-1-A-1-L Power Supply

The MAMAC Systems PS-200-1-A-1-L is a field-proven 24Vdc output power supply designed specifically for demanding HVACR control loops and industrial automation peripherals. Engineering-grade construction features a split bobbin transformer with 3500 VRMS isolation, ensuring high-tier protection for sensitive electronic components. This model is configured for a 115Vac line voltage input and delivers a 1.5 Amp fully regulated output. The low height chassis design is essential for tight control panel installations where vertical clearance is a premium. Unlike standard open-frame units, this linear DC power supply includes an integrated, easily accessible 3AG inline fuse and fully insulated terminal strips, eliminating the need for custom field modifications or additional soldering. With a ripple voltage of less than 2.0 mV pp and internal thermal overload protection, it provides the clean, stable power necessary for precise BAS (Building Automation Systems) and DDC (Direct Digital Control) applications.

• Enhanced Safety: Features 3500 VRMS isolation and a fully insulated terminal strip to protect technicians from accidental shock.
• Panel-Ready Design: The low height chassis fits standard enclosures without the need for custom mounting brackets.
• Circuit Protection: Integrated short circuit and thermal overload protection ensures the unit shuts down safely during faults and resumes operation once cleared.
• Clean Signal: Extremely low ripple (under 2.0 mV pp) prevents signal interference in sensitive HVAC transducers and sensors.
• Installation Efficiency: Eliminates field soldering with pre-configured multi-position terminal strips for both primary and secondary connections.

Can the output voltage be adjusted in the field?
Yes, the MAMAC PS-200-1-A-1-L is technically adjustable across a 5.0 to 25.0 VDC range via an onboard trimmer, though this specific model is factory-optimized for 24Vdc applications.

What happens if the 1.5 Amp load is exceeded?
The unit features internal current limiting. If the load exceeds 130% of its rated capacity, the supply enters a dormant state to prevent hardware damage, recovering automatically once the overcurrent condition is resolved.

Does this unit require an external fuse?
No, it includes a factory-mounted inline fuse holder using standard 3AG fuses, making maintenance straightforward without additional component wiring.
