engine overspeed protection Switch
Dynalco SW-200B提供可靠的發(fā)動(dòng)機(jī)超速保護(hù)。它有三個(gè)可調(diào)繼電器設(shè)定值：第一個(gè)是超速。兩個(gè)輔助設(shè)備的用途包括曲柄斷開、發(fā)電機(jī)磁場閃爍和速度監(jiān)測。設(shè)定值是現(xiàn)場可編程的，可以在不超速的情況下進(jìn)行測試。外殼是密封的。SW-200B速度開關(guān)提供三個(gè)可調(diào)繼電器設(shè)定點(diǎn)，用于發(fā)動(dòng)機(jī)超速保護(hù)、曲柄斷開、發(fā)電機(jī)磁場閃爍和速度監(jiān)測，并具有完全的現(xiàn)場編程能力。
Dynalco SW-200B provides reliable engine overspeed protection. It has three adjustable relay setpoints: number one is overspeed. Uses for the two auxiliaries include crank disconnect, generator field-flashing, and speed monitoring. Setpoints are field-programmable and can be tested without overspeeding. Housing is gasketed and sealed.SW-200B Speed Switch provides three adjustable relay set points for engine overspeed protection, crank disconnect, generator field flashing, and speed monitoring with full field-programming capability.
