11. SPECIFICATIONS
IMS01T28-E4
11-3

Power feed forward (PFF) input [optional]
Input range: 0 to 10 V AC (50 Hz, 60Hz)
Power feed forward (PFF) input can be measured up to 240 V AC *
using a PFF transformer [PFT-02A].
(Measurable low limit voltage: 35 V AC)
When connecting a PFF transformer, install it near the SRZ and
connect the SRZ to the output terminals (6 and 7) of the PFF
transformer with the minimum wiring length.
* OVERVOLTAGE CATEGORY II
