At 50V AC max. switching voltage, the following
applies:
Max. switching current 1A~ at p.f. =1
Max. switching current 0.12A AC at p.f. = 0.4
At max. 30V DC switching voltage, the following
applies::
Max. switching current 0.8A (resistive loads)
For functions see Section 4.3.3 and 4.3.1.2 (status
word)
A serial connection to automation unit or a PC can be realized via
connector X300 on the PMU.The cables must be shielded and
connected to ground at both ends. (See Sec. 3.3.2). Thus,
the rectifier/regenerating unit can be controlled and operated from
the central control station or control room.
