New isolated DC-to-DC converters from Bel Fuse

The converters are available in two options: the PST50W series with a 50 W power isolated output and the PST75W series with a 75 W power isolated output.

Both DC-to-DC converters offer 4200 Vdc isolation and an 8:1 input range (9.5 ~ 75), and are available in open-frame and enclosed versions with options for 12, 15, 24, and 28 output voltage. Housed in a chassis mount package, the products have an extended operating temperature range of -40 up to +105°C and feature short circuit, over current, over voltage, over temperature and undervoltage lockout protections.

With reinforced insulation, the converters are EN/IEC 62368 certified and meet UL 62368 power supply standards. Featuring a built-in EMI filter and baseplate—no longer requiring customers to purchase separately—along with remote on/off control, the converters are a reliable option for EV charging, industrial, and remote telecom applications, such as cell towers. In addition, the converters meet EN 50155 and EN 45545-2 standards, making them suitable for railway designs.

In consumer electronics, industrial automation, and IoT deployments, the chassis mount DC-to-DC converters deliver essential power isolation and safeguarding functionalities for optimal performance and longevity. With a wide input range and comprehensive protection features, these converters ensure stable power delivery in diverse operational environments, meeting the stringent demands of modern applications across various sectors.
