The POWEC PMP 6.24 SIC is a compact, high-reliability DC/DC converter module designed for industrial automation, process control, and embedded systems where stable, isolated power is critical. Operating from a 24 VDC nominal input, it delivers a regulated 24 VDC output at 6.5 watts, making it ideal for powering sensors, small relays, signal conditioners, or isolated I/O circuits in PLC and DCS cabinets. Despite its modest power rating, the POWEC PMP 6.24 SIC incorporates robust features such as 3 kV galvanic isolation, short-circuit protection, and wide operating temperature tolerance—ensuring dependable performance in electrically noisy or thermally challenging environments.
Manufactured by POWEC (a European specialist in industrial power solutions), the POWEC PMP 6.24 SIC belongs to the PMP (Power Module for Panel) series, known for its dual-mount flexibility (PCB solder or optional DIN rail clip) and conduction-cooled design without fans or moving parts. Its primary value lies in providing clean, isolated power where ground loops, voltage transients, or EMI could otherwise disrupt sensitive electronics. In distributed control architectures—such as those from ABB, Siemens, or Rockwell—the POWEC PMP 6.24 SIC serves as a silent enabler of signal integrity and system resilience, often deployed alongside analog input modules or communication gateways that demand noise-free auxiliary power.

Main Features and Advantages
High isolation for noise-sensitive applications: The POWEC PMP 6.24 SIC provides 3 kV of galvanic isolation between input and output, effectively breaking ground loops that commonly cause measurement drift in analog sensor circuits (e.g., RTDs, pressure transmitters). This makes it indispensable in precision data acquisition systems where even millivolt-level interference can corrupt readings.
Robust protection and thermal performance: Unlike generic converters, the POWEC PMP 6.24 SIC includes comprehensive protection mechanisms—automatic recovery from short circuits, over-current limiting, and thermal shutdown. It operates reliably up to +85°C ambient without derating, thanks to its low-loss topology and metal baseplate that acts as a heat spreader. This ruggedness is why it’s specified in oil & gas, rail, and factory automation settings.
Dual-mount versatility and space efficiency: Measuring just 50.8 x 25.4 x 10.2 mm, the POWEC PMP 6.24 SIC fits into tight panel spaces. It can be directly soldered onto a custom PCB for embedded designs or mounted on a DIN rail using an optional clip (sold separately)—offering flexibility for both OEMs and system integrators. No external components are needed for basic operation, simplifying BOM and assembly.
Wide input range and stable regulation: Accepting 18–36 VDC, the POWEC PMP 6.24 SIC tolerates brownouts and voltage spikes common in industrial 24V networks (e.g., during motor startups). Its output remains tightly regulated within ±2%, ensuring consistent performance for downstream electronics. With >82% efficiency, it minimizes wasted heat—a key advantage in sealed enclosures where cooling is limited.
Long-term availability and compliance: POWEC designs its PMP series for extended lifecycle support, avoiding frequent obsolescence. The POWEC PMP 6.24 SIC meets global safety standards (UL, CE, IEC 62368-1), facilitating integration into certified control panels worldwide. For engineers maintaining legacy systems or designing new modular architectures, this combination of reliability, compliance, and compactness makes the POWEC PMP 6.24 SIC a preferred choice for auxiliary power.
Application Field
The POWEC PMP 6.24 SIC is widely used wherever clean, isolated 24V power is needed for low-power industrial electronics. In process automation, it powers isolated barrier modules for intrinsically safe (IS) loops in hazardous areas—providing the necessary separation between safe and hazardous zones while delivering stable voltage to field transmitters. Similarly, in PLC control panels, the POWEC PMP 6.24 SIC supplies isolated power to analog input cards handling 4–20 mA signals, preventing ground-induced errors that compromise control accuracy.
In machine building and robotics, the POWEC PMP 6.24 SIC energizes encoder interfaces, safety relays, or small solenoid drivers that must operate independently of the main logic power rail. Its immunity to electrical noise ensures reliable operation near VFDs or servo drives. Railway signaling systems also deploy the POWEC PMP 6.24 SIC due to its wide temperature range and compliance with EN 50155 vibration/shock requirements (when properly mounted).
For renewable energy applications—such as solar inverters or battery management systems—the POWEC PMP 6.24 SIC provides bias power for monitoring circuits that must remain electrically separated from high-voltage DC buses. Even in test and measurement equipment, it isolates sensor excitation circuits from data acquisition hardware. Across all these scenarios, the POWEC PMP 6.24 SIC delivers quiet, dependable power in a footprint small enough to embed anywhere—proving that sometimes, the most critical component is the one you never notice failing.

Installation and Maintenance
Pre-installation preparation: Before installing the POWEC PMP 6.24 SIC, verify that the input voltage stays within 18–36 VDC under all operating conditions—including startup surges and load dumps. If mounting on PCB, ensure adequate copper area around the pins for heat dissipation; for DIN rail use, secure the optional clip firmly to prevent vibration-induced loosening. Keep high-noise conductors (e.g., motor cables) away from the output wiring to preserve isolation benefits.
Maintenance recommendations: The POWEC PMP 6.24 SIC is maintenance-free due to its solid-state design and absence of electrolytic capacitors with limited lifespan. However, periodically inspect for dust buildup in enclosed panels, as excessive contamination can impede passive cooling. If output voltage drops or the module overheats, check for sustained overloads or short circuits on the output side—though protected, repeated fault events may degrade long-term reliability. Replace the POWEC PMP 6.24 SIC immediately if the case shows discoloration or physical deformation, as this indicates internal failure.
