UMG 96RM-PN
Determine the pulse value
Set the pulse length
Set the pulse length in accordance with the requirements
of the connected pulse receiver.
At a pulse length of 30 ms, for example,
the UMG 96RM generates a maximum number of
60,000 pulses (see Table "maximum number of pulses"
per hour.
Determining the maximum connected load
Example:
Current transformer
= 150/5 A
Voltage L-N
= Max. 300 V
Power per phase
= 150 A x 300 V
= 45 kW
Power at 3 phases
= 45kW x 3
Maximum connected load = 135 kW
Calculating the pulse value

When using the digital outputs as pulse
outputs, the auxiliary voltage (DC) must
have a max. residual ripple of 5%.
