Determining the pulse value
Setting the pulse length
Set the pulse length according to the requirements
of the connected pulse receiver.
For a pulse length of 30 ms, for example, the UMG
96RM can issue a maximum number of 60,000 pulses
(see Table "Maximum Pulse Number") per hour.
Determining the maximum connected load
Example:
Current transformer = 150/5 A
L-N voltage = max. 300 V
Power per phase = 150 A x 300 V
= 45 kW
Power for 3 phases = 45 kW x 3
Maximum connected load = 135 kW

output.

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