MMC75B-1-J

The Cosel MMC75B-1-J is an AC-DC power supply unit designed for industrial and commercial applications. This open frame converter features a chassis mount type and offers three distinct output voltages: +5V, +12V, and -12V. It operates with an input voltage range of 85-132 VAC or 110-170 VDC and boasts an efficiency of 75% at full load.

The unit provides regulated outputs with line regulation up to 48mV and load regulation up to 120mV. Ripple and noise are kept within specified limits, with a maximum of 120mVp-p for the +12V and -12V outputs. The operating temperature range is from 0°C to 65°C, making it suitable for various environmental conditions. Safety features include overcurrent protection that automatically recovers when the fault condition is removed.

With dimensions of 193.0mm x 93.0mm x 42.0mm, the MMC75B-1-J is designed for integration into larger systems. It holds cURus agency approvals and complies with FCC-B conducted noise standards, indicating its suitability for ITE (Commercial) applications. The power supply also includes isolation ratings for input-case, output-case, and output-output.

Key specifications include a start-up time of 100ms maximum and a hold-up time of 15ms typical. The output voltage for the +5V rail is adjustable within a range of 5.00-5.25V. This power supply is a reliable component for applications requiring multiple DC voltage rails from a single AC input.
