Designed for rolling stock applications, the new converter family PURC/PWRC from MTM POWER completes its upper power range with the series PWRC650. In order to keep the weight as low as possible, these converters are non-encapsulated, but are built into a U-bracket case. The continuous power rating is 650W, allowing a 50% power-boost to switch on critical loads and selectively switch off secondary circuits. This boost is provided for five seconds, followed by an automatic reduction to constant nominal power.
As the first converter series of MTM POWER dedicated to rolling stock demands, PWRC650 operates as a hybrid, combining digital and analogue techniques. Whereas the digital control allows high flexibility in regards to overload characteristics, parallel operation, and adjustment of output voltage and current, among others, the analogue part is mainly used to provide and ensure safety-relevant circuit functions as a protective fallback level.
Designed to operate at 72 or 110 VDC input voltage, PWRC650 offers all the advantages of a state-of-the-art railway converter, such as power-good-signal via floating contact, as well as RC-controlled standby mode for energy saving and preserving the battery’s life time. Of course, PWRC650 provides all basic parameters required to comply with all relevant standards, such as EN50155, EN50121-3-2, and EN 45545-2.
