Murata Power Solutions recently announced the addition of an open frame AC/DC converter to its PQ line. The PQU1000 is an open frame 1000W AC/DC converter, designed for critical applications that require a high level of safety. The open frame power supply comes in a compact package and is designed to work in convection cooling mode up to 800W making it suitable for a low noise environment.
According to the company, the compact power supply measures 127mm x 203.2mm with a “U” channel form factor with industry-standard mounting holes. The device can achieve efficiency up to 95% and is suitable for crucial applications such as industrial and healthcare applications. The module also meets IEC62368-1 and EN60601-1 third edition standards which are essential for industrial and healthcare applications. The company also claims that the power converter is suitable for Body Floating (BF) applications and complies with 2 x MOPP (IN/OUT) and 1 x MOPP (OUT/FG) safety requirements. The product produces a low level of noise and heat due to its high efficiency, therefore, reducing the overall energy consumption of the system. The module also features the Power Management Bus (PMBus) protocol which enhances the communication with the power supply unit.
Murata says that in order to meet the demands of the medical and industrial market, the PQ series incorporates a proprietary combination of leading-edge design topology with LLC power transfer technique and digital control and communication. According to the datasheet, the module also provides safety features such as overcurrent protection, over-voltage protection, and over-temperature protection. The converter can work without a fan when supplying power up to 800W but requires an additional fan or blower.
The PQU1000 is suitable for use in indoor equipment such as 3D printers, test and measurement instruments, displays, Power over Ethernet (POE) switches, furthermore, it can be used in critical applications such as healthcare applications like a power supply for hospital beds, ventilators, and other medical instruments.
