The Melcher PSR & PSA series switching regulators by Bel Power are ideal converters for harsh environments, or applications where high reliability and efficiency are essential. Typical applications include railways, military, industrial, telecoms as well as more general transportation applications.
Conformal coating on all PCBs make the PSR and PSA series converters suitable for applications all over the world, from extreme cold to very high humidities, the PSR and PSA series will offer long term reliable solutions.
PSR and PSA sereis converters are suitable for EN50155 and EN50121 railway applications where input to output isolation is not required, such as lighting, wiper control and door interlocks. Further information is available on request.
PSR & PSA series positive switching regulators utilize a robust, non-isolated topology that provides high power-conversion efficiency across a wide range of operating conditions. These products feature conformally-coated PCB assemblies and are ideal power sources for a broad array of rugged and industrial environment applications.
Additional features include:
High levels of power-conversion efficiency remain virtually constant over the entire input-voltage range.
Wide output adjustment ranges, high reliability, low output ripple, no minimum load operation, and excellent dynamic response.
PSRs & PSAs can be optimized for specific applications through wide-range output voltage adjustments and a variety of readily available options and accessories.
Products with input voltages up to 144V are specially designed for secondary switched and battery-driven mobile applications.
No power derating over the entire operating temperature range; -40 to 71°C extended-temperature-range options
