PRODUCT UPDATE 29 www.power-mag.com Issue 2 2023 Power Electronics Europe Extending the portfolio of electrolytic polymer hybrid capacitors available from Panasonic Industry, the ZTU series is an AEC-Q200-qualified series, designed for reliability and rugged operation. It joins the existing ZT and ZC capacitor series. It is available with a rated voltage 25 to 35V DC / 220 560µF and an 80% increase in ripple current capability compared to the ZC series, says the company. The ZTU has been proven for 4000 hours at 125°C and 135°C for applications where high temperature tolerance and high current capability is required. Suitable applications are in DC/DC or AC/DC inverters, robotics, rectifier circuits as well as automotive applications where conditions are harsh and demanding. The company also offers a vibration-proof version in both 8.0 and 10mm diameter versions. They are able to handle shocks of up to 30G, while the standard parts have a vibration tolerance of 10G. According to Panasonic Industry Europe’s Hirofumi Maruyama: “The ZTU series is setting new standards with its ripple current and capacitance specs and reliably guarantees circuit safety at one of the highest temperature ranges currently available on the market”. The first two models in the UMA series are the 30W UMA30F and the 60W UMA60F. The UMA30F measures 50.8 x 76.2mm and 21.7mm high or 24.2mm for the UMA60F. The power supplies have a universal input range Compact power supply is suitable for medical applications Hybrid capacitor series sets new standards, says Panasonic Industry of 85 to 264V AC. They comply with international safety standards and are designed for demanding body floating (BF) applications. They comply with 2MOPP (in/out) and 1MOPP (out/FG or frame-ground) safety requirement. They are available in up to five output voltages of 5, 12, 15, 24, and 48V DC. Medical applications require robust and reliable power supplies, says Cosel. The company’s flyback topology enables the power supplies to be operated within a universal input range of 85 to 264V AC, and with a typical efficiency up to 91% at high line. There are four single output voltages available as standard for the UMA30F model: 5V/3A, 12V/2.5A, 24V/1.3A and 48V/0.65A. There are five options in the UMA60F model: 5V/6A, 12V/4.5A, 15V/3.5A, 24V/2.5A and 48V/1.25A. Output is factory adjusted to a fixed value, but in applications where output voltage adjustment is required an option with potentiometer is available. Features in the UMA series include inrush current limiting circuitry, overcurrent, and over-voltage protection. The power supplies can be operated in an environmental temperature range of -20 to 70 degrees C. A derating may apply, depending on the final equipment assembly style and cooling conditions, advises the company. The UMA series’ models are approved in accordance with ANSI/AAMI ES60601-1 and EN60601-1 3rd Edition. In the case of body floating applications where patient leakage current must be less than 100µA, with its 75µA figure, the power supplies are below that limit. The UMA series meets ANSI/AAMI ES60601-1, EN60601-1 3rd, C-UL (equivalent to CAN/CSA-C22.2 No.60601-1), UL62368-1, EN62368-1, CUL (equivalent to CAN/CSA-C22.2 No.62368-1) and complies with EN60335-1. Three options are available including adjustable output voltage (Y), terminal block (T), and for applications requiring additional safety the UMA30F and UMA60F are available with reinforced isolation in conformance with the IEC class II (E). The UMA30F weighs 80g and the UMA60F weighs 120g maximum. The UMA series has a five-year warranty and conforms to the European RoHS and Low Voltage Directives.
