6 - Operating characteristics
Introduction
Ekip Touch has been developed and certified to work in specific environmental, electrical, and
mechanical conditions. All the information is available in the
Technical Catalog
(see page 4).
The following paragraphs only describe the electrical and power characteristics for correct
operation of Ekip Touch and related electronic accessories.
Electrical
characteristics
The correct operation of Ekip Touch is guaranteed with primary power and voltage in the
designated ranges and having well-defined characteristics:
Parameter
Operation limits
Primary power
0.03 .. 16 In
(NOTE)
Primary voltage
0 .. 690 V AC
Rated frequency
50 / 60 Hz ±10%
Peak factor
Compliant with IEC 60947-2
NOTE: range referred to each phase; In refers to the rated size of the Trip unit, available
in models ranging from 40 A to 250 A.
Ekip Touch can also be powered directly by the internal power sensors:
Parameter
Operation limits
Minimum three-phase power on startup
> 0.2 In
Auxiliary power
supply
Ekip Touch can be connected to an external auxiliary power source, useful for enabling some
functions such as communication on the Local Bus, recording of manual operations, some
measurements, and the data logger.
The auxiliary power supply can be supplied by modules from the
Ekip Supply
range (see page
130 for more operational details) or be powered directly through the side terminal board.
The direct connection must guarantee the following operating conditions:
Parameter
Operation limits
Voltage
24 V DC galvanically isolated
Tolerance
±10%
Maximum wave
±5%
Maximum surge current @ 24 V
10 A for 5 ms
Maximum rated power @ 24 V
4 W
Connecting cable
Insulated with ground cable (characteristics equal
to or greater than Belden 3105A/B)
IMPORTANT: if the Trip unit is connected directly the power supply must be
galvanically isolated and must guarantee the insulation characteristics referred
to in IEC 60950 (UL 1950) or their equivalent
