PLC & Control Systems: Power Siemens S7-1200/1500 PLCs, distributed I/O modules, and HMI panels with confidence. The PSU100L's low ripple output ensures error-free communication and precise control logic execution.

Process Automation: Drive 24V DC sensors, transmitters, and valve actuators in chemical processing, water treatment, and pharmaceutical manufacturing. The wide temperature range supports installation in harsh process environments.

Machine Building: Integrate into packaging machinery, conveyor systems, and assembly lines. The compact footprint and DIN rail mounting simplify OEM panel designs and reduce wiring complexity.

Building Automation: Supply reliable power to HVAC controllers, access control systems, and lighting management networks. The high efficiency reduces heat generation and energy costs.

Solutions & Integration

The SITOP PSU100L seamlessly integrates with Siemens TIA Portal for centralized power monitoring when paired with SITOP Manager software. Parallel operation capability allows redundant configurations for critical applications—simply connect multiple units with diode modules for N+1 redundancy.

For applications requiring battery backup, combine with SITOP DC UPS modules to create uninterruptible 24V DC systems. The standardized SITOP platform ensures mechanical and electrical compatibility across the entire product family.

Frequently Asked Questions

Q: Can this power supply operate at 110V AC input?
A: Yes, the wide input range (85-264V AC) fully supports 110V AC operation without derating. Full 120W output is available across the entire input voltage range.

Q: What is the maximum capacitive load this unit can drive?
A: The PSU100L can charge up to 2200μF capacitive loads at startup. For larger capacitances, use inrush current limiting or staged power-up sequences.

Q: Is this suitable for outdoor installations?
A: The IP20 rating requires installation in protected enclosures. For outdoor applications, mount inside NEMA 4X or IP65-rated cabinets with adequate ventilation.

Q: How do I adjust the output voltage?
A: Use the front-accessible potentiometer to adjust output from 24V to 28V DC. This allows compensation for voltage drops in long cable runs or fine-tuning for specific equipment requirements.
