OVERVIEW

The JNF-074 board is a power supply filter. It is designed as an isolaton / noise filter for the TRAK DRIVE (tm ) boards. The JNF-074 allows up to 100 ma. at 23.5 volts of power to be drawn from any Mitsubishi Z-200 drive. The JNF-074 is slightly smaller then the JNF-076 but the terminal blocks are located such that it may be used in the place of the JNF-076 without rewiring a panel. It has a socket for the 220 volt input power connector. There are no connections to that socket.

INPUTS

TB1 L1, L2, L3, L4, F1, F2
