E-1048-8C. CUBIC version
Power supply LINE +
T*e DC power supply with *all Ri
battery and generator etc.
Voltage ratings UN DC 12 V / DC 24 V
Operating voltage US: DC 9...32 V
Load circuit LOAD
Load output Power MOSFET, high side switching
Max. current rating IN 25 A
T*es of loads resistive, inductive, capacitive, lamp
loads, motors (depending on duration
of inrush current)
Current rating range IN 1 A...20 A (fixed
ratings)
up to 85 °C ambient without load
reduction, 25 A up to 60 °C.
Two basic versions with factory preset
ratings:
version 1: 1 A / 2 A / 3 A / 5 A / 7.5 A / 10 A
version 2: 15 A / 20 A / 25 A
Induced current consumption
I0 of the unit (OFF condition) < 1 mA
T*ical voltage drop UON
at rated current IN (at 25 °C)
IN UON IN UON
1 A 50 mV 10 A 110 mV
2 A 55 mV 15 A 70 mV
3 A 60 mV 20 A 90 mV
5 A 80 mV 25 A 120 mV
7.5 A 90 mV
Switching point t*ically 1.3 x IN
(-40 °C...+85 °C:
1.1...1.5 x IN)
Trip time (standard curve) t*ically 200 ms with
switch-on onto
overload and/or load increase on duty
Current limitation version 1: t*ically 75 A
version 2: t*ically 350 A
Temperature disconnection power transistor > 150 °C
After trip - resettable via external control signal
(low-high) at control input IN+
- reset of supply voltage
Parallel connection of channels for loads of 25 A plus,
several units of
identical current ratings may be
connected in parallel. To ensure equal
distribution of current between units,
symmetrical design of the supply feed
is necessary (length and cross section).
Leakage current in OFF
condition version 1: max. 100 μA
version 2: max. 500 μA
Free-wheeling diode integral
for connected load version 1: max. 40 A
version 2: max. 100 A
Delay time ton / toff t*. 5 ms / t*. 1.5
ms (EMC filter in
(resistive load) control input)
The Smart Power Relay E-1048-8C.- is a remotely
controllable
electronic load disconnecting relay with three functions
in a single unit:
● electronic relay
● electronic
overcurrent protection
● status indication
The 7 pin CUBIC version is designed for use with standard
automotive
relay sockets. A choice of current ratings is available
from 1 A
through 25 A. An operating voltage range of DC 9...32 V
allows the
connection of DC 12 V and DC 24 V loads.
In order to switch and protect loads remotely, it has
until now been
necessary to connect several discreet components together
- an electro-mechanic relay, control cable and integral
contact
to close the load circuit
- an additional protective element (circuit breaker or
fuse) for cable
or equipment protection
- a device for current measurement (shunt)
Now t*e E-1048-8C combines all these
functions in a single unit,
thus minimising the number of connections
in the circuit and
thereby reducing the risk of failures.
