Overview of Tyco Electronics JAHW Series Power Modules
The datasheet details the JAHW Series Power Modules, specifically the JAHWOSOF, JAHWO7SF, and JAHWIOOF models. These DC-DC converters are noted for their compact size, high efficiency, and versatility in power supply applications. The input voltage range for these modules is 36 to 75 VDC, and they provide an output of 3.3 VDC with power ratings ranging from 33 W to 66 W. The datasheet originates from June 2001 and reflects Tyco Electronics’ commitment to high-quality electronic components.
Key Features and Benefits
The modules boast a small form factor, excellent efficiency (88% typical), and a constant frequency operation. They are designed with industry-standard pinouts and a metal baseplate for robust thermal performance. The series offers protections such as overtemperature, overcurrent, and output overvoltage, all through hiccup mode. Additionally, they include remote sense and on/off functionality, and the output voltage is adjustable. These modules meet various international standards, including the ETSI 300-132-2, EN60950, and directives 73/23/EEC and 93/68/EEC, making them a compliant choice for global applications.
Applications and Options
These power modules can be utilized in distributed power architectures, computer equipment, and communications equipment. They offer options such as heat sinks for extended thermal management, different remote on/off logic configurations, and basic insulation for safe integration (-B version only).
Performance and Electrical Specifications
With respect to electrical specifications, the modules operate within a specified input voltage range and feature input specifications that include inrush transient and reflected-ripple current parameters. The operating case and storage temperature ranges are listed to ensure proper operation and longevity of the device. The modules come with a 1500 VDC isolation voltage rating. It’s crucial to note that these power modules must be used in conjunction with an input line fuse as specified by the datasheet for safety reasons, as they are not internally fused.
Certifications and Standards Compliance
Certification from ISO 9001 for manufacturing facilities ensures quality production. The power modules are also recognized under UL, CSA, and VDE standards, bearing the CE mark which underscores their adherence to European Union directives.
Manufacturer and Safety Information
The datasheet emphasizes the requirement of using an input line fuse for safety, conforming to the standards outlined in the safety considerations section. These directives ensure the safe and reliable operation of the power modules in various applications.
Tyco Electronics Corp. is identified as the manufacturer of these power modules, demonstrating a commitment to providing advanced technological solutions in the field of electronics.
