If there is an overload, DC output current is composed of the max. current of the
buffer module
and the current of the DC mains supply. To avoid overloading the DC output
circuit, external protection is required!

Setup
The unit is switched-on by connecting the DC supply to the terminal 'InputOutput'.
The unit is switched-on by connecting the DC supply to the terminal 'UInput'.
If the units are used in installations that require overloads for testing (e.g. acc. to EN60204-1 /
VDE0113 Part 1 19.4 Voltage test) the unit has to be separated from the test set-up before voltage is
applied. (Original text EN60204-1 Components that are not designed for this test voltage have to be
disconnected during the test.) Check if the connections are correct before first start-up! Establish
electrical connections only when the module is disconnected from the supply!
Operation
The Emparro Cap will be connected parallel to the load. The unit is supplied with energy from the input
voltage (Terminal Input / Output) to charge the capacitors. Charging the ultracapacitor is only possible if
the input voltage is ≥ 22,5V DC. If a high load current is required at the same time, the charging time will
increase. If the input voltage is 21,6V DC the device is in standby mode. In this status the LED 'UIN OK' is
on and the relay is energized.
Connection
Before connection: compare the data of the DC supply with the data on the type plate and check for
compliance. Connect according to the indications of the terminals (see circuit diagram and configuration).
Buffer time in sec. =
The useable energy is dependent on the discharge current.
With long buffering times an internal consumption of approx. 40 must be considered!
Calculating the buffer time as-new condition:
Energy of the capacitor in J x I
K
Output current x output voltage
