1 For double output models both outputs loaded with I
o nom.
2 Valid for -7 versions without option E. This is the nominal value at 25 °C and applies to cold models at initial switch-on cycle. Subsequent
switch-on/off cycles increase the inrush current peak value.
3 For 1 s max.
4 AC operating frequency range is 47 to 440 Hz (440 Hz for 115 V mains). For frequencies
≥ 63 Hz refer to Safety and Installation Instructions.
Input Transient Protection
A suppressor diode and/or a VDR (depending on input voltage
range) together with the input fuse and a symmetrical input filter
form an effective protection against high input transient voltages
which typically occur in most installations, but especially in
battery-driven mobile applications.
Nominal battery voltages in use are: 12, 24, 36, 48, 60, 72, 110,
and 220 V. In most cases each nominal value is specified in a
tolerance of –30% to 25%.
In certain applications, surges according to RIA 12 are
specified in addition to those defined in IEC 60571-1. The
power supply must not switch off during these surges and
extremely wide input range is required. The ES input range
for 110 V batteries has been designed and tested to meet
this requirement.
