PSLC3

Product catalog summary

Specifications:
The document outlines specifications for a series of unregulated DC power supplies, type PSLC3, with various output voltages (12VDC, 15VDC, 24VDC, 28VDC) and corresponding current ratings (6.0A, 4.5A, 3.0A, 2.5A). Each unit has a power rating of approximately 68-72 Watts and an efficiency of 86%. The dimensions are consistent across models at 100x75x110 mm, and each unit weighs approximately 1.74 kg. The power supplies are designed to be overload and short-circuit proof, suitable for tropical environments, and have a high mean time between failures (MTBF) of over 400,000 hours.

Procedures and Standards:
The power supplies comply with various international standards, including VDE, EN, UL, and CSA. They are designed with safety features such as extra low safety potential (PELV and SELV), and are protected against overload and open circuit conditions. The units are suitable for parallel connection and are not protected against polarity reversal at the output. They are designed to operate within a temperature range of -30°C to +80°C, with a derating starting from 40°C.

Recommendations:
It is recommended to maintain a respective distance of 15mm for cooling purposes. The units are self-cooling and do not require additional cooling mechanisms. They are designed for use in environments with up to 95% relative humidity and are vibration-proof according to IEC standards.

Key Data from Diagrams:
The load-current diagram illustrates the relationship between output voltage and current for different models, showing how the output voltage remains stable across varying load currents. The diagram also highlights the nominal input voltage and current requirements for optimal performance.
