3.3 Input
The input can be supplied with voltages in the range from 12 to 25 Volts, whereby the polarity is
irrelevant because there is a rectifier in the device.
The internal load of the input is 660 Ohm and 47µF.
If a cable is connected to the input of the device, the cable length must be less than 3.0 m.
3.4 Output
The output provides a DC voltage. For new batteries, the output voltage is up to 12.8 volts. Depending
on the load, however, this voltage also drops significantly because the batteries have a certain internal
resistance.
Depending on the load, the current at the output can reach values of up to approx. 50 A at the moment
of switching on, with the output transistor delivering no more than approx. 10 A shortly thereafter.
In general, however, alkaline batteries are not capable of delivering such high currents in the long
term. Accordingly, the current decreases at high loads.
The output of the device is short-circuit proof. The intelligent switching transistor is protected against
overcurrent, overload, overtemperature, overvoltage and electrostatic discharges.
The output can drive resistive, inductive and capacitive loads.
The standard duration of the output pulse is approx. 3.5 seconds if the device is controlled by the PFE
Profi Midi 1 Output. On request, the device can also be adapted if a shorter or longer pulse duration is
requested.
When using other firing systems, the pulse duration depends on the charging voltage and the capacity
of the firing capacitor.
The cable connected to the output of the device must be less than 3.0 m long.
TIP
3.5 Maximum number of confetti shooters with heating coil
A maximum of three confetti shooters with heating filaments can be operated in series. The parallel
connection of confetti shooters is not recommended.
TIP
3.6 Maximum load when controlling magnetic valves
The device can drive magnetic valves with a coil voltage of 12 Volts DC and a coil power of up to 32
Watts. Only one solenoid valve should be connected per device.
We recommend the use of cables with a copper strand with a conductor
cross-section of at least 1.5 mm². Keep the cables as short as possible
so that losses are kept to a minimum.
If the confetti shooters are of inferior quality and the heating coils are
subject to a too large spread, it is possible that not all shooters trigger. In
this case, only one or two shooters can be reliably triggered.
