Voltage regulators
EST 519/2
ESD 5 K 2
These two voltage regulators keep output voltage constant at a prede-
termined value, with an input voltage that constantly oscillates between
140 and 250 V AC. It is possible to connect a 22 A  x load.
EST 519/2 features an input voltage selector (60-130 V / 140-260 V)
and it has been designed in a 19” rack format to  t  xed installations.
ESD 5 K/2 for its own has handles for easy transport.
Many features are available to ensure output signal integrity: protec-
tions against overvoltage (255 V), overheat (95º) and overload (23 A).
The voltage regulators automatically turn off if a value is exceed. They
emit an acoustic signal and indicate the problem on the display. It is
possible to select output voltage (1% or 3%) with a simple switch.
Time delay circuit (between 3 and 6 sec.) avoids noises coming from
the interrupter before the normal operating mode starts. A large display
shows information like input, output and current voltage.
